Main ideas
Disconnected marketing tools slow teams down · Customer listening sets the product roadmap · Early-stage founders should do the work, automate, and delay hiring
Ed Hallen is known for co-founding Klaviyo, which builds marketing and customer relationship software for consumer brands.
Their posts explain how the company developed products around customer needs, from customer data and email marketing to messaging channels and B2C CRM.
Hallen also writes about startup growth, including why founders should understand jobs firsthand and focus on finding customers before defaulting to fundraising.
Follow their work for a founder’s account of building a software business and concrete views on connected marketing tools and startup choices.
Hallen connects product direction to operating experience.
In one post, they trace Klaviyo’s growth from customer database and email marketing into attribution, SMS, reviews, and CRM, framing the progression as a response to customer needs.
In another, they make “omnichannel” tangible, naming tools for coordinating campaigns across email, SMS, WhatsApp, and push, and for measuring more than the final customer touch.
Their startup writing offers a different perspective: founders should do jobs themselves to learn what they require, automate where possible, and delay hiring until necessary.
The mix gives readers a view of how Hallen describes Klaviyo’s product choices and practical arguments about building a company.
Ed Hallen's public posts focus on how marketing software should work and how startups should be built.

Their recurring argument is that disconnected tools and premature hiring slow companies down; the fix is coordinated customer data, close listening to customers and hands-on work.
They also argue that companies between unicorns and very small local businesses can be strong, lower-risk businesses.
Their posts offer product and operator notes from Klaviyo and reflections on entrepreneurship.
Disconnected marketing tools slow teams down
Hallen argues that marketing teams often run 6 to 18 tools for day-to-day programs, and that these tools do not work well together.
Read more
The result, they say, is slower teams that spend more and deliver less. Coordinated systems, not more stitching together of separate tools, are the fix.
Hallen compares the problem to planning a road trip before smartphones, when directions, weather and music each came from a separate tool with nothing connecting them. At Klaviyo's London conference, they listed announced features designed to address it: one omnichannel campaign builder across email, SMS, WhatsApp and push; Channel Affinity AI for choosing message, moment and medium per customer; linear multi-touch and omnichannel attribution; and multi-language support, RCS and wider SMS coverage.
Hallen says Klaviyo has built by listening to customers from day one.
Read more
Each major expansion responds to what customers wanted, with the goal of giving brands one place to manage customer relationships across the whole journey, not just marketing.
Hallen traces the sequence from a customer database in 2012 to email marketing in 2013, then attribution and optimization, SMS, Reviews, CDP, thousands of partners and hundreds of integrations, leading to Klaviyo B2C CRM. They describe the CRM as a single place for customers to manage relationships across the entire journey.
The product story moves from database and email tools toward a broader B2C CRM, applying the same customer-listening rationale at each stage.
Early-stage founders should do the work, automate, and delay hiring
Hallen argues that founders should do as many jobs as possible for as long as possible to understand what each involves and which skills matter.
Read more
Then they should automate what they can. Hiring should wait until there is genuinely no alternative.
Hallen's post about a conversation with Aaron Schwartz on Klaviyo's early days sets out three rules: founders do the jobs themselves, automate each job where possible, and do not hire until absolutely necessary. They repeat the hiring rule for emphasis.
Hallen frames this as advice for the early days of a startup, not a general rule for a scaled organization.
The Mighty Middle is a lower-risk route to building a valuable company
Hallen highlights a Harvard Business Review article co-authored with Benjamin Hallen about the space between unicorns and mom-and-pop startups.
Read more
The argument: these businesses can offer lower risk, higher reward and higher founder value capture, and entrepreneurship education should show more examples of founders building outside the traditional venture path.
Hallen connects the argument to Klaviyo's own start with Andrew Bialecki.
They say that when they started Klaviyo, many questions were about the pitch or fundraising, but they stayed focused on finding customers with a problem they could solve.
They wished for more examples of founders who built great businesses without following the traditional path.
International expansion is backed by early customer proof
Hallen treats early customers in a market, along with a local office and local events, as evidence of real commitment to that market.
Read more
The Sydney conference post ties regional expansion to personalization, marketing and entrepreneurship rather than making a generic global claim.
Hallen notes that four of Klaviyo's earliest customers were Australian brands, including two school uniform companies. They also say Klaviyo opened its first Sydney office three years before the post and credit the local team and speakers for making the K:SYD conference happen.
This is the clearest post for the question "what has this person built, and how do they describe it?"
Read more
A newcomer gets a short chronological account of the product line and the reasoning behind it.
Announcing Klaviyo B2C CRM, Hallen credits co-founder Andrew Bialecki and traces the build step by step: a customer database in 2012, email marketing reworked in 2013, then attribution and optimization, SMS, Reviews, CDP, thousands of partners and hundreds of integrations.
The framing is that each step followed customer requests.
The goal: a single place for a brand to manage customer relationships across the whole journey, not just marketing.
The claim that it is "the only CRM built for B2C brands" is the argument, not decoration.
For brands planning a campaign
For a brand assessing Klaviyo or a potential partnership, this is the platform positioning in its most compressed form: customer data ownership and consolidation. It offers a workable hook for a campaign about integration or platform strategy aimed at ecommerce teams.
Answers "what does omnichannel actually mean in this person's work, and where are they taking it?"
Read more
The post names specific features rather than staying at slogan level.
Hallen compares marketing today to road trips before smartphones, when directions, weather and music each came from a separate tool with nothing connecting them.
The same fragmentation, they say, shows up in marketing teams running six to eighteen tools that do not work well together.
The result: slower teams that spend more and deliver less.
Hallen lists the announced features: an Omnichannel Campaign Builder spanning email, SMS, WhatsApp and push; Channel Affinity AI for choosing message, moment and medium per customer; linear multi-touch and omnichannel attribution that credits assists rather than only the final touch; and multi-language support, RCS and wider SMS coverage.
For brands planning a campaign
The named capabilities are concrete enough to anchor a technical or partner-facing campaign: attribution, channel selection and messaging reach are checkable claims. Useful when a brief involves comparing messaging or analytics vendors rather than creator content.
Answers "how far does this person's work extend beyond the US, and how do they talk about customers?"
Read more
It is the most concrete account of regional history in the posts here.
After Klaviyo's first Sydney conference, Hallen notes that four of the company's earliest customers were Australian brands, two of them school uniform companies, and that the first Sydney office opened three years earlier.
The post credits the local team and speakers, and links to further insights shared at the event around personalization, marketing and entrepreneurship.
The tone is an event recap, not analysis.
For brands planning a campaign
Evidence of an active APAC presence and willingness to appear at regional events, relevant to a brief involving an Australia or APAC audience. Customer detail is thin, so ask for customer proof before using this in a campaign built around customer outcomes.
Answers "what does this person argue about entrepreneurship beyond marketing software?"
Read more
It is the clearest example of Hallen making a general business argument rather than a product announcement.
Hallen announces a Harvard Business Review online article written with Benjamin Hallen about the "Mighty Middle" of startups: the space between unicorns and mom-and-pop businesses, which they describe as a lower-risk, higher-reward path that can leave founders with more value.
Hallen connects the idea to Klaviyo's own start with Andrew Bialecki.
They recall that most early questions were about the pitch or fundraising while the two stayed heads down looking for customers with a problem they could solve, and say more examples of founders building outside the traditional path would have helped.
For brands planning a campaign
Positions Hallen as a founder-education voice with reach beyond ecommerce tooling, suited to founder-focused audiences, business media or entrepreneurship programming. The post describes the article rather than presenting it, so ask to review the article before relying on its argument.
Answers "how did this company actually operate in its early days?"
Read more
This is the most transferable, hands-on example in the set for anyone weighing practical credibility over product messaging.
In a post sharing a conversation with Aaron Schwartz about Klaviyo's early days, Hallen sets out three rules they believe in strongly: founders should do as many jobs themselves as they can, for as long as possible, to understand what each job involves and which skills matter; then automate what can be automated for each job; and hire only when there is genuinely no alternative. They repeat the last rule for emphasis.
For brands planning a campaign
A strong fit for operator and founder audiences where the appeal is judgment rather than product.
It also gives a campaign a concrete point of view for content or an event session.
Ask to review the linked interview before quoting the three rules.
Consolidating omnichannel marketing and tool sprawl
In a London EMEA conference post, Hallen says marketers use 6–18 tools for day-to-day programs that do not integrate, slowing teams and raising costs.
Read more
They present Klaviyo’s response as one omnichannel campaign builder for email, SMS, WhatsApp and push; Channel Affinity AI for message, moment and medium; linear multi-touch and omnichannel attribution; and expanded language, RCS and SMS coverage. Their argument: brands should replace stitched-together tools with a more coordinated system.
A road-trip analogy frames the problem: separate tools for directions, weather and music that are not connected, followed by product announcements as the fix.
For brands planning a campaign
Brands evaluating a marketing technology partner can assess Hallen’s public position on omnichannel orchestration, attribution and channel consolidation. The topic prompts questions about how a partner frames integration, customer experience and measurable cross-channel outcomes.
Hallen traces Klaviyo’s product expansion from a 2012 customer database to email marketing in 2013, then attribution, optimization, SMS, reviews, CDP, partners and integrations, culminating in Klaviyo B2C CRM.
Read more
They cite listening to customers and giving them one place to manage customer relationships across the journey—not only marketing—as the driver.
A chronological account of milestones, from database to B2C CRM.
For brands planning a campaign
Useful for assessing how a founder narrates product evolution and customer data ownership. B2B SaaS partner evaluations can examine whether Hallen’s public story connects customer problems to platform expansion and CRM consolidation.
International expansion through local customer proof
In a Sydney conference post, Hallen notes that four of Klaviyo’s earliest customers were Australian brands, including two school uniform companies, and that Klaviyo opened its first Sydney office three years before the post.
Read more
They connect the conference to personalization, marketing and entrepreneurship, and to giving marketers control of their brands’ direction.
A local origin story paired with a current conference as evidence of market commitment.
For brands planning a campaign
Brands considering APAC or local-market expansion can assess Hallen’s approach of pairing customer history with in-market events and offices. The topic speaks to partner credibility in a specific region, not just global product claims.
Founder-led early operations and hiring discipline
In a conversation with Aaron Schwartz, Hallen describes an early-Klaviyo approach: founders should do as many jobs as possible for as long as possible to understand what each requires, automate where possible, and hire only when truly necessary.
Read more
The advice applies to early startup days.
Three early-stage principles: do the jobs, automate, delay hiring.
The advice is explicitly about the early days of a startup; it is not a general claim about later-stage organizational design.
For brands planning a campaign
Relevant for founder-audience content or a partner brief on early-stage operating discipline. Brands can assess Hallen’s practical stance on staying close to customers and the work rather than scaling headcount early.
The “Mighty Middle” and non-traditional entrepreneurship
Hallen highlights a Harvard Business Review article co-authored with Benjamin Hallen about the “Mighty Middle” of startups—opportunities between unicorns and mom-and-pop businesses that can offer lower risk and higher founder value capture.

They connect the idea to Klaviyo’s early focus on finding customers with a solvable problem rather than chasing pitch or fundraising questions, and call for more examples of founders building outside the traditional path.

The full article is not included here; the post states the co-authorship and summarizes the argument, but does not provide detailed findings.
For brands planning a campaign
B2B SaaS or entrepreneurship-focused brands can assess Hallen’s public interest in durable, mid-scale company building and founder education. The topic supports content about alternative growth paths, customer-first validation and founder value capture.
Hallen’s posts document Klaviyo as the business they co-founded with Andrew Bialecki, and cover building and launching Klaviyo’s marketing software and events.

Their posts introduce Klaviyo products, conferences, and customer work, including B2C CRM, omnichannel campaign tools, and the K:LDN and K:SYD events.
Ed Hallen writes product and operating notes from Klaviyo, focused on how marketing software should work and how to run a startup in its early years.

The London conference post gives the fullest version of the omnichannel argument: marketing teams juggling six to eighteen disconnected tools move slower and spend more, and Hallen proposes one system to plan campaigns across email, SMS, WhatsApp and push, with attribution that credits every touch.
The B2C CRM post traces the product's history through customer requests, from a 2012 database to email, SMS, reviews and a CRM.
The Mighty Middle post makes the case for companies between unicorns and small local businesses, alongside Hallen's account of building Klaviyo by finding customers with a solvable problem rather than chasing pitch questions.
The Sydney and early-hiring posts are shorter and more situational.

Torres walks through Composer's natural-language querying, its connection to Klaviyo data, Customer Agent's language coverage and an integration that lets another tool act on a business's Klaviyo account. Hallen lays out the omnichannel campaign builder, channel selection and attribution features announced at Klaviyo's London conference.
Torres writes as a recent joiner, going release by release with attention to AI and data tools such as natural-language SQL, AI agents, a Composer mobile app and a Meta partnership. Hallen more often steps back to argue for a strategy—around tool sprawl, customer listening as a roadmap, or early-stage hiring—and includes company-history and entrepreneurship posts rather than feature rundowns.
Both built the same company and return to the same theme: customers should own their data and relationships rather than rent them from third parties.

Bialecki argues that Apple's privacy changes reward first-party, owned relationships and ties ownership to company culture around Klaviyo's listing. Hallen makes the same case in product terms, describing a single place to manage the customer journey, and writes about building Klaviyo together.
Bialecki's posts cover company-defining moments—the NYSE listing, Apple's privacy shift and a culture built on ownership—and carry that tone. Hallen's are more often working notes: how tool consolidation should work, why customer requests shape the roadmap, and how founders should hire in the early days.
Both work where ecommerce marketing meets the systems that run it, and both write concretely about Klaviyo-connected flows.

Marciniak describes in-store purchases syncing into Klaviyo to enable omnichannel email and SMS, and tracking offline sales back to paid media. Hallen argues for one coordinated system across email, SMS, WhatsApp and push instead of stitched-together tools.
Marciniak writes as the agency doing the building: Shopify Plus rebuilds, a thirteen-store POS rollout and a WordPress-to-Shopify migration with reported ROAS figures.
The evidence is a finished client project.
Hallen writes from the platform side, focusing on product direction and company principles rather than client results or ROAS numbers.
Buyers should ask for client outcome data if they need it.

A B2B software or marketing technology company wants an established operator voice for founders and marketing operations leaders: a content or event partnership on consolidating omnichannel marketing tools, attribution, and customer data instead of stitching together six to eighteen disconnected systems.
Read more
Reasons
Ed Hallen explains omnichannel marketing in concrete terms. In the K:LDN post, they compare marketing teams to road trips before smartphones: directions, weather, and music each came from a separate tool, with nothing connecting them. They say marketers often run six to eighteen tools that do not work well together, slowing teams and increasing spend. The announced features are specific: an Omnichannel Campaign Builder across email, SMS, WhatsApp, and push; Channel Affinity AI for choosing message, moment, and medium; linear multi-touch and omnichannel attribution that credits assists, not just the final touch; and multi-language support, RCS, and wider SMS coverage. A martech partner can test these details.
Ed Hallen can tell a platform story that moves from customer problems to product expansion. The B2C CRM post traces a 2012 customer database, 2013 email marketing, then attribution, optimization, SMS, Reviews, CDP, thousands of partners, and hundreds of integrations, ending with Klaviyo B2C CRM. The stated driver is listening to customers and giving them one place to manage relationships across the whole journey. For a B2B SaaS brief, this shows how they connect integration, data ownership, and platform strategy.
The posts also cover early-stage operating discipline. Ed Hallen sets out three rules: founders do as many jobs as they can for as long as possible, automate what can be automated, and hire only when there is no alternative. The advice is specifically about the early startup years, giving founders and operators a practical point of view rather than a product pitch.
A Harvard Business Review article post adds a broader argument about entrepreneurship. Ed Hallen announces a co-authored article with Benjamin Hallen about the “Mighty Middle” of startups, between unicorns and mom-and-pop businesses, described as lower risk and higher founder value capture. The post links the idea to Klaviyo’s early focus on finding customers with a solvable problem instead of chasing pitch or fundraising questions. They summarise the argument as follows; ask for the full article to assess it directly.
The Sydney conference post offers regional customer proof and shows a willingness to appear at in-market events. Ed Hallen notes that four of Klaviyo’s earliest customers were Australian brands, two of them school uniform companies, and that the first Sydney office opened three years before the post. For a brief involving APAC or local-market credibility, this is concrete evidence of presence.
Unresolved gaps
The posts do not describe sponsorship or paid partnership formats. Ask for current rates, usage rights, paid content requirements, and an inquiry route.
The posts do not include audience demographics, job roles, company types, geography, or buyer seniority. The 8,694 LinkedIn followers are platform-reported; ask for audience data to confirm whether they include the marketing technology buyers sought.
Only five LinkedIn posts were read in full. Ask for the linked Aaron Schwartz interview, the full Harvard Business Review article, and examples from any other channel or format.
Verdict
Strong fit for expert-led content or an event aimed at audiences seeking expertise in omnichannel marketing, product strategy, and early-stage operating discipline. The public work shows specific, checkable expertise in these areas. Before booking, ask for commercial terms: the posts do not publish a media kit, rate card, usage rights, or inquiry route.
When to choose a specialist
A consumer skincare brand wants a paid Instagram Reels and TikTok series featuring product unboxing and lifestyle visuals, with a documented rate card and verified audience demographics for a direct-to-consumer campaign.
Read more
Reasons
The five posts are LinkedIn text posts about Klaviyo product launches, London and Sydney conferences, a B2C CRM narrative, early-stage hiring advice, and a co-authored Harvard Business Review article. None features product reviews, unboxing, beauty, skincare, fashion, or lifestyle content.
The posts do not describe sponsorship or paid partnership formats. Ask for rates, deliverables, usage rights, exclusivity terms, and a media kit.
The posts contain no visual or short-form video content: no Reels, TikTok, photos, or video work to assess for a skincare campaign.
The only audience signal is 8,694 LinkedIn followers. For a consumer brand decision, ask for demographics, age, geography, occupation, and purchase behaviour data; a professional LinkedIn following does not establish a skincare or direct-to-consumer audience.
The channel context conflicts with the brief: the reviewed work focuses on B2B software and founders and operators, while the brief calls for consumer social content and paid lifestyle promotion.
Verdict
Poor fit based on the posts reviewed. The work is LinkedIn text about B2B software, conferences, and startup operations. There is no consumer lifestyle, beauty, unboxing, or visual social content, and no audience data to confirm a match with skincare buyers. Ask for examples of relevant creative and audience data before reconsidering.
A worked campaign example
Angle
Run a three-part “from six tools to one system” series with Ed Hallen as the operator voice. The hook comes from the K:LDN post: marketing teams running six to eighteen tools that do not work well together, slowing teams and increasing costs. Keep the series focused on practical buyer questions, not a Klaviyo product pitch.
Brief
B2B software company or marketing technology brand: a founder-and-operator content partnership on omnichannel tool consolidation and customer data ownership.
Episode one
Title: “Why your marketing stack is slower than your road trip.” Use the directions, weather, and music comparison. Ask viewers to list every tool used in a single campaign, then mark which ones share data automatically. Output: a stack inventory template with columns for tool, owner, data in, data out, and manual step.
Episode three
Title: “Build, buy, or stitch: the operating questions.” Use the B2C CRM chronology, from a customer database in 2012 to one place for customer relationships. Ask what data ownership, integration ownership, and customer-listening processes a brand needs before adding another tool. Output: a one-page brief with five questions to ask any marketing technology partner.
Episode two
Title: “What omnichannel actually requires.” Use the named K:LDN capabilities: one campaign builder for email, SMS, WhatsApp, and push; channel affinity for message, moment, and medium; linear multi-touch and omnichannel attribution that credit assists; and multi-language, RCS, and SMS coverage. Ask the marketing operations guest which capabilities their current stack cannot support. Output: an attribution and channel-coverage checklist.
Format
Record one 30-minute conversation between Ed Hallen and a marketing operations leader, then cut it into three short written or video episodes. Give each episode one decision tool: a stack inventory, an attribution check, and an integration-ownership checklist. A companion one-page evaluation brief can be gated or ungated, depending on the campaign goal.
Lead follow up
End each episode with a concrete next step: download the checklist, book a stack review, or request the partner evaluation brief. If the campaign requires paid promotion, first collect a media kit, rate card, usage rights, exclusivity terms, and audience demographics; the posts do not provide them.
Why it works
The angle draws on Ed Hallen’s strongest posts: clear problem framing, named product capabilities, a chronological platform story, and early-stage operator judgment. It gives readers a reason to trust the expertise before any commercial ask, and turns the missing sponsorship terms into a collection task rather than an invented offer.
For a B2B martech content or event campaign, choose Elias Torres when the audience needs a current product leader walking through shipped capabilities and agentic marketing, rather than a long-arc founder story.
Read more
The posts show a first-month product update after joining Klaviyo, covering natural-language querying of warehouse data through Composer, MCP, scheduled chats, brand kits, audit and autofix, a global Customer Agent supporting more than 100 languages with automatic locale detection through Shopify Markets, voice handling for customer calls, and a Composer iOS app.
A second post describes moving fast to make Klaviyo a launch partner with Meta for Muse for Small Business, connecting Muse to Klaviyo data for winback campaigns, and the stated principle of putting Klaviyo intelligence where marketers already work.
This fits a buyer seeking recent product specifics and a partner-integration example.
Ed Hallen's posts cover startup operating discipline and the platform's long evolution, rather than the recent, product-heavy posts from Elias Torres.
Elias Torres's posts don't cover early-stage founder roles, hiring discipline or the multi-year platform chronology Hallen's posts provide.
A campaign seeking a veteran co-founder to explain company-building over years would get less from these sources.
Ask for audience and commercial terms; Elias Torres's posts don't provide them.
For a B2B martech content or event campaign, choose Andrew Bialecki when the audience needs a co-founder- or CEO-level strategic voice on privacy, first-party data, ownership and company mission.
Read more
The posts include a detailed argument that Apple's privacy changes validate owned, first-party customer relationships over third-party data and anonymous advertising.
A later post frames Klaviyo's culture around ownership, a customer-first mentality and empowering creators to own their destiny, while marking an IPO-stage milestone at the NYSE.
This fits a campaign about why brands should own customer relationships and data rather than rent audiences, or a leadership-and-mission segment that needs a milestone moment.
The tradeoff is less current, hands-on omnichannel product detail.
Andrew Bialecki's posts date from 2021 and 2023 and don't include the recent campaign-builder, attribution, SMS or WhatsApp, or AI feature specifics found in Ed Hallen's recent posts.
A buyer seeking tactical stack-consolidation questions, current product names or recent event proof would find less here.
Ask for audience and commercial terms; Andrew Bialecki's posts don't provide them.
For a B2B martech content or event campaign, choose Andre Marciniak when the audience needs an implementation and ecommerce-infrastructure proof point rather than a platform executive.

The posts show a Shopify Plus rebuild and a 13-store Shopify POS rollout for Fantastic Framing, with unified inventory, reporting and operations, offline sales attributed back to Meta ads, omnichannel journeys tracked online and in-store, and in-store purchases synced into Klaviyo for email and SMS flows.
A second post gives a WordPress-to-Shopify-Plus migration case with a claimed 6.87 ROAS on a Monday without new creatives or budget, tying the improvement to native checkout, faster load speeds, cleaner product detail pages, tighter user experience and better data flowing back to ad platforms.
This fits a campaign seeking concrete retail or ecommerce migration proof and data plumbing between store, ads and Klaviyo.
The tradeoff is a project- and agency-based perspective, not a founder-operator or platform-strategy voice.
Andre Marciniak's posts take a case-study approach and don't cover company-building, omnichannel tool consolidation at a leadership level or platform roadmap thinking.
A campaign seeking a named platform executive to explain why marketing teams run six to eighteen disconnected tools needs a different source.
Ask for audience and commercial terms; Andre Marciniak's posts don't provide them.
