Sebastian Karlsson shares practical perspectives on complex B2B sales, CRM and sales methodology.
Their posts connect sales processes to the tools teams use, while stressing that AI and systems cannot replace trust and sound judgment in conversations.
They also write candidly about the parts of selling that do not end in a win.
Their work offers a grounded view of how process, technology and human selling fit together.
Karlsson makes sales principles tangible through process examples and personal experience.
In a post about Membrain’s Insight Engine, they map familiar seller challenges—from finding decision-makers to planning the next step—to CRM tools designed to support the sales process.
Elsewhere, they argue that credibility comes from genuine conversations, not simply following a script; that can mean making a follow-up call to confirm details.
Their account of a deal that went to another decision-maker adds a useful counterpoint: a strong approach does not guarantee a win.
Together, these examples show how CRM can support the way people sell without making technology, scripts or outcomes the whole story.
Karlsson’s posts connect complex B2B sales to the way people actually sell: CRM should reflect the sales method, AI can help with defined tasks but cannot create trust, and credibility matters more than following a script.

They also separate good work from guaranteed outcomes, using a lost deal to make that point.
A CRM should show how the team sells, not just track pipeline stages
Karlsson argues that broad pipeline phases do not capture a team’s sales process.
Read more
They say the process and methodology should be built into the CRM, because how a team sells can affect why it wins.
In one post, Karlsson describes pursuing a deal against four suppliers by showing how sales process and methodology could sit inside the CRM. The prospect’s team liked the approach, but a global CRM agreement held by its owners ultimately shaped the decision.
AI can help with sales tasks, but trust is not an automation problem
Karlsson presents AI as useful for specific work, while questioning whether it can create the liking and trust needed in complex B2B sales.
Read more
Their position is practical rather than anti-AI: use tools to support the process, but do not mistake task assistance for a trusted relationship.
In a post about Membrain’s Insight Engine, Karlsson lists tasks such as finding target companies and decision-makers, drafting meeting summaries from rough notes, and suggesting next steps. A separate post asks whether people expect AI to create trust in a sale.
Credibility comes from genuine conversations, not reciting a sales script
Karlsson says that following the “right” wording from a sales handbook left them sounding less genuine.
Read more
They argue that being comfortable with how you sell helps build credibility, even if an unscripted meeting means making extra calls later to confirm details.
Karlsson recalls dropping the script and being themself in sales meetings, then needing to call back to check information they had forgotten to ask for. They present that tradeoff as preferable to sounding polished but inauthentic.
Karlsson distinguishes the quality of a sales effort from its outcome.
Read more
A seller cannot control every decision, they write, but can keep delivering at a high level. The point makes room for honest discussion of losses rather than treating every lost deal as proof of poor selling.
After their team’s approach was accepted and a contract sent, Karlsson learned that the buying decision rested elsewhere, under a parent company’s existing CRM agreement. They describe the effort as a kind of win even though the deal did not close.

The post answers "what does this person build and sell?" with a concrete list rather than a job title.
A pre-launch post about Insight Engine, a feature set inside the Membrain CRM.
Karlsson sets it against what they describe as several hectic years in AI, when products generate hype for a few months and then lose momentum.
They say the team returned to customer feedback to identify what changes behaviour in complex B2B sales.
The post lists problems they say they struggled with across eight years in the CRM industry: too few leads, not knowing who to contact, finding decision-maker phone numbers, choosing which industry to prioritise, writing meeting summaries and knowing whether the call was really listened to, and deciding what to do next in the sales process.
It maps each problem to a capability: finding companies by size and industry; adding decision-makers such as CEO, CRO, sales manager, CIO and HR; pulling direct numbers, email and LinkedIn profiles in one click; drafting meeting summaries from rough notes; and guiding the seller through the next step.
The post closes with a webinar invitation and an offer to show how they use the tool themselves in ten minutes.
For brands planning a campaign
Useful for vendors looking for someone who can demonstrate a CRM or AI sales feature through specific workflows and named buyer roles, rather than offer general commentary on AI in sales. The explicit before-and-after problem list is ready-made collaboration material.
The clearest statement of the world Karlsson works in and the people around them.

It answers "who does this person work with?" without requiring readers to piece it together from individual posts.
Written in English, the post describes a trip to London with Henrik Öquist to join sales trainers and consultants at Objective Management Group University.
Karlsson notes that OMG assesses over 80,000 salespeople a year and has aggregated more than two million assessments.
They describe eight years at Membrain spent combining what those consultants do for clients, weaving their training, processes and methodologies into a CRM built for revenue growth.
The result reads as a short field report from the sales-training community rather than a product pitch.

Read it for the position itself and to judge whether it matches a campaign's view of CRM and AI.
A short post asking whether a team's CRM reflects how it sells, beyond broad pipeline phases.
Karlsson argues that AI only goes so far in complex B2B sales, that how you sell becomes why you win, and asks whether readers are letting AI create liking and trust for their product or service.
There is no product announcement or link; the post puts its opinion to readers as a challenge.
For brands planning a campaign
A sharp discussion hook for content about where AI helps in a sales process and where human behaviour and judgement determine the outcome. Suits a vendor willing to take a stance against automating trust.
Shows what kind of seller Karlsson is and what they changed.
Read more
It gives newcomers a direct account of their stated sales philosophy.
An account of trying to sell "by the book", using the correct wording from what Karlsson calls the holy sales handbook.
They say the result lacked genuineness and authenticity, and that the strength they now see as a core asset was missing.
Things started to happen, according to the post, after they dropped the script and dared to be themselves—even when that meant making extra calls afterwards to confirm details forgotten in the meeting.
The post argues that confidence in a sales conversation comes from being secure in who you are and how you sell, that being genuine makes you trustworthy, and that trustworthiness always sells best, in their opinion.
It ends by asking readers what they do to build trust in sales meetings.
For brands planning a campaign
Strong material for sales-enablement content about scripts versus genuine conversations. The candid account of personal change could also anchor a longer collaboration, provided the brand accepts the anti-script position.
Shows how Karlsson talks about failure and the politics behind CRM decisions.

It makes clear whether they can carry an honest win-loss discussion, not just tell success stories.
A field story about coming out on top against four suppliers.
The team agreed that its approach was best and solved the customer's challenges; a kickoff was planned and a contract sent.
Karlsson says they already knew the customer had a global CRM agreement through its owners, despite the system not having worked for the customer's sales approach for several years.
They went ahead to show what was possible when the sales process and methodology sit inside the CRM.
The decision, however, was not the customer's to make.
The post concludes that you can do everything right and still lose, that the outcome is beyond your control, and that you can always keep delivering at a high level.
It asks readers whether they have also won without taking the deal home.
For brands planning a campaign
A good fit for content about win-loss reviews, procurement realities and parent-company software agreements. The post also signals a willingness to publish a loss, making it useful for collaborations that value candid accounts—but a poor fit for vendors seeking only positive outcome stories.
Sebastian argues that a team’s sales approach should be visible in the CRM, not just expressed as pipeline phases.
Read more
In one post, they ask whether the CRM reflects how the company actually sells, and say that AI only goes so far in complex B2B sales because how you sell becomes why you win. In another, they describe going all in on a deal to show what is possible when sales process and methodology are woven into the heart of the CRM, even against an incumbent global system that had not worked for the prospect for years.
Sebastian often frames the point as a direct question to the audience, then grounds it in a specific deal story or product example.
For brands planning a campaign
A brand selling CRM or sales-enablement software can evaluate Sebastian for content that connects CRM configuration to real sales behavior. The strongest angle is showing how a sales process works in a CRM, rather than promoting features in the abstract.
AI as a practical assistant, not a replacement for trust
Sebastian presents AI as useful for specific sales tasks: finding companies of the right size and industry, identifying decision makers, retrieving direct numbers and emails, drafting meeting summaries from rough notes, and guiding next steps in the sales process.
Read more
They warn that AI alone goes only so far in complex B2B sales, and ask whether you want AI to create liking and trust in your sales.
Sebastian lists specific sales problems, maps each to a product function, then invites a short personal demonstration.
The detailed AI features come from a specific product launch. Ask for examples of how they apply beyond that tool.
For brands planning a campaign
For an AI-in-sales or sales-intelligence vendor, Sebastian can demonstrate practical AI workflows inside a CRM while drawing a line at relationship-building. A collaboration could pair a product walkthrough with their argument that human trust still decides complex sales.
In a personal reflection, Sebastian recalls trying to sell by the book, using the “right” wording from a sales handbook.

They say they lacked genuineness and authenticity, and that letting go of the script and being themself made things happen.
They now see credibility as one of their strengths and write that credibility sells best.
They close by asking readers what they do to create credibility in sales meetings.
For brands planning a campaign
A brand focused on sales coaching, conversation intelligence, or authenticity in sales can evaluate Sebastian for reflective content that challenges scripted selling and opens a peer discussion. This personal angle can complement product-led posts.
Learning from the sales assessment and training community
Sebastian describes traveling to London with Henrik Öquist for Objective Management Group University, joining European sales trainers and consultants.
Read more
They note that OMG assesses over 80,000 salespeople a year and has aggregated more than 2 million assessments. They also say that over eight years at Membrain, they have combined consultants’ work for their clients by weaving training, processes, and methodologies into a CRM built for revenue growth.
For brands planning a campaign
A sales training, assessment, or enablement brand can evaluate Sebastian for content that bridges assessment data and CRM practice, as well as event-adjacent or community-facing collaborations. Their framing is collaborative rather than purely promotional.
Sebastian tells the story of being one of four suppliers, agreeing on the best approach, planning a kickoff, and sending a contract—then learning the decision was not with the team because of a global CRM agreement through the owners.

They write that sometimes you do everything right and still lose, but you can always keep delivering at a high level. They end by asking whether others have won without bringing home the deal.
For brands planning a campaign
A brand in sales performance or CRM can evaluate Sebastian for content on resilience, process discipline, and the gap between effort and outcome. This angle reaches sales audiences through shared experience rather than product features.
Sebastian ties new product releases to a vision of elevating the sales profession within complex B2B sales.
Read more
They invest in the sales training community and describe weaving consultants’ methods into CRM. Across posts, they treat complex B2B sales as a discipline that deserves purpose-built approaches, not generic pipeline mechanics.
For brands planning a campaign
A brand that wants to be associated with seriousness and craft in B2B sales can evaluate Sebastian for manifesto-style or community-building content, as well as practical product posts. They can carry a message about raising the standard of the profession.
Sebastian Karlsson's posts tie them closely to Membrain, the CRM platform they say they have worked with for eight years.

They introduce the Insight Engine product launch to their audience and describe attending Objective Management Group's London university event for sales trainers and consultants—a professional association rather than a commercial arrangement. Ask for clarification about any sponsorship, affiliate, or paid partnership, which the posts do not disclose.

Employment
Karlsson writes as someone inside Membrain: they say they have spent the last eight years there weaving consultants' sales training, processes, and methodologies into a CRM built for revenue growth, and they announce an Insight Engine release using "we" and speak about "our customers" and how they use the product themselves as a seller.
Karlsson describes flying to London with Henrik Öquist to join European sales trainers and consultants at Objective Management Group University.

They cite OMG's assessment volume as context for the training and methodology work they do in CRM. The post shows attendance and reference, not a commercial relationship.
Sebastian Karlsson writes about complex B2B sales and the systems that support them, from the perspective of someone who uses a CRM while selling.

Start with the pair of posts arguing that a CRM should show how a team actually sells, not just track pipeline stages.
One recounts how an approved proposal was overruled when a parent company's global CRM agreement decided the outcome.
The material then follows two tracks.
The commercial track covers AI as a narrow assistant for finding target companies, identifying decision-makers and drafting meeting summaries, while cautioning that AI alone does not create liking or trust in a complex sale.
The reflective track covers dropping a memorised sales script, building credibility by being genuine in the meeting and separating the quality of a sales effort from whether the deal closes.
For product-anchored examples, start with the CRM and AI posts; for coaching-style content, start with the credibility and lost-deal posts.
Writes short first-person posts in Swedish about how B2B sales conversations and forecasts really go, using the same reflective, story-led format Karlsson uses to describe a deal decided elsewhere.
Read more
Both write from long selling experience and address the reader directly at the end of a post.
Lantz focuses on buyers' own research and sellers' willingness to admit a deal is dead. Unlike Karlsson, they don't connect those points to CRM configuration or a software product.
Publishes practitioner explainers for a B2B audience, walking through a complicated corporate function step by step before offering a structured way to act on it—the same teaching mode Karlsson uses for CRM and sales process.

Tull writes about sustainable procurement, supply-chain transparency and CSRD reporting, not selling or CRM. The overlap is in approach rather than topic.
Explains business-software decisions in plain language, including a rule of thumb for choosing no-code, low-code or full-code integration.

Like Karlsson, they explain what a system should do for the people who use it.
Kløvning writes about integrations, system reliability and outages, not sales methods, conversations or how a team's selling should be represented in a tool.
Sebastian Karlsson's audience case rests on topic relevance rather than scale.

The LinkedIn profile lists 6,729 followers (observed 8 October 2026).
The five posts, published between 14 October 2025 and 25 May 2026, address people doing or leading complex B2B sales: sellers working with a CRM-driven process, sales leaders weighing sales methodology, and the sales trainers and consultants they describe meeting at Objective Management Group University in London.
The content points to a narrow practitioner niche, not a broad-reach buy.
For a B2B sales-software collaboration, ask for an audience breakdown or survey covering country, job function and seniority, plus recent results for comparable topics and formats, before planning placement.

The five available posts are Sebastian Karlsson’s own writing about complex B2B sales, CRM practice and Membrain product releases; none states a sponsored-content offer, rate, audience package or outreach process for brand collaborations.
The closest thing to a commercial invitation is a product announcement that points readers to a Membrain webinar and offers a ten-minute walkthrough of the tool.
That is a software sales route, not a creator partnership route.
Before planning a paid collaboration, ask about available formats, deliverables and contact details; none are established here.
A CRM or sales-methodology vendor launching a workflow feature wants a short content collaboration — a demo-led LinkedIn post or video plus a webinar appearance — aimed at sales leaders and sellers at complex B2B companies.
Read more
Sebastian Karlsson is a strong fit.
They already produce the exact format the collaboration needs.
In the Insight Engine post, they list the seller problems they say they lived with across eight years in the CRM industry — too few leads, not knowing who to contact, finding decision-maker phone numbers, which industry to prioritise, meeting summaries, and what to do next — then map each one to a specific capability before offering a ten-minute personal walkthrough.
That problem-to-capability structure can be reused as launch material, from someone who sells the product rather than describing it from outside.
The event post supplies the second requirement: eight years at Membrain spent weaving sales trainers' processes and methodologies into a CRM built for revenue growth, plus a standing relationship with the Objective Management Group community, which gives a webinar a credible guest or audience route.
The short CRM and AI post supplies the position — how you sell becomes why you win, and AI only takes you so far in complex B2B sales — so the collaboration argues something instead of listing features.
The deal-loss post shows they can carry the awkward part of CRM content honestly: a team wins on approach, plans the kickoff, and still loses because the decision sits with a parent company's global agreement.
One practical constraint: the audience is a narrow practitioner niche.
Run this as a qualified-reach and credibility play, and judge it on demo requests or webinar attendance from people who run complex B2B sales, not on follower volume or impressions.
When to choose a specialist
An AI writing or productivity app wants a reach-priced paid LinkedIn campaign aimed at a broad, non-specialist audience, with the message that AI can now handle qualification and relationship-building for sales teams end to end, delivered through scripted copy.
Read more
The mismatch is on both message and measurement.
The CRM and AI post argues the opposite: AI takes you only so far in complex B2B sales, and Karlsson asks readers directly whether they want AI creating liking and trust for their product.
The credibility post says the change that worked was dropping the sales handbook script and speaking in their own voice, so a campaign built on scripted copy would put them against their stated position, in public and in a way readers can see.
The posts record 6,729 followers on one platform and show an audience of people doing or leading complex B2B selling, not a broad or consumer-facing audience.
Before pricing a reach-based buy, ask for audience demographics, per-post performance, a documented sponsorship format, a rate card, and an inquiry route.
This is a mismatch between the campaign and the creator, not a judgement that the work is weak — the same posts that make them wrong for a volume-driven consumer play make them right for a practitioner campaign.
A worked campaign example
Worked angle for the good-fit campaign: a three-post LinkedIn sequence plus one webinar, built around one configured sales step rather than a feature list.
Post one states the position in Karlsson's own framing — if the way your team sells is not visible in the CRM beyond pipeline phases, the pipeline is decoration, and in complex B2B sales AI alone stops short of the relationship.
Post two is the demonstration: a screen recording of roughly 90 seconds in which one named seller problem, such as not knowing which decision-maker to contact, is configured and resolved inside the CRM, closing with the offer of the ten-minute personal walkthrough they already use in product posts.
Post three is the win-loss piece: the deal where the team's approach beat four suppliers and the decision still belonged to the owners' global agreement, told with the customer's constraint named and no softened ending.
The webinar pairs Karlsson with a sales trainer from the assessment community they travel with, on weaving a sales methodology into CRM configuration, while the vendor configures the object live.
Distribution runs through the vendor's sales-leader list and their LinkedIn, cross-posted in Swedish and English because the posts use both.
Measure qualified demo requests, webinar attendance from accounts running complex B2B sales, and the quality of comment replies — not impressions.
State the trade-off up front: this will not produce large top-of-funnel volume, and the value is that the people who respond are already wrestling with the exact problem.
Choose Karl-Johan Lantz instead when the collaboration should argue that the sales conversation itself has to change.
Read more
Both posts describe buyers who arrive already informed: they have read, compared suppliers, asked an AI assistant and talked to peers who bought something similar.
The meeting is often a verification exercise rather than an exploration.
The argument is that information is no longer the rep's currency; the remaining value lies in moving someone from where they are to where they need to be.
That suits a methodology, training or sales-enablement launch carried by someone who says they spent thirty years selling this way better than it suits a feature demonstration.
The second post is written for sellers weighing whether to keep an unqualified deal in the forecast.
The trade-off is product distance.
These posts focus on buyer behaviour and the seller's own reasoning; the CRM appears only as something scanned before a meeting, not as something configured or shown.
A vendor wanting a 90-second screen recording, a configured sales step or a demo-led feature post will find less raw material here than in Sebastian's content.
The collaboration would need to supply both the product story and the technical demonstration.
Choose Peter Tull instead when the campaign is about ESG, CSRD reporting and sustainable procurement rather than selling.
Read more
The posts explain how procurement functions gain transparency across supplier tiers, why risk analysis on social topics should not follow a spending-based rule, and how value-chain data has to be collected and governed to support sustainability reporting. A vendor selling compliance or procurement software that helps companies gather supplier data would find a closer subject match than a sales-software vendor would.
The trade-off is subject fit, and here it is decisive.
This comparison is for a content collaboration on complex sales and CRM aimed at sales leaders, but these posts do not address that ground.
A sales-software brief would be a poor match regardless of how well the writing is done.
The second post also promotes the author's own paid advisory subscription packages, which a vendor would need to address directly.
Choose Stefan Kløvning instead when a campaign needs the systems side of the same problem: where customer data lives and how CRM, ERP and other tools stay in sync.
Read more
One post works through no-code, low-code and full-code integration choices, with a plain rule of thumb for choosing between them.
It starts from the everyday mess of registering the same customer in several places.
The other argues, drawing on a global cloud outage, that software built on third-party platforms needs mapped risks, backups and tested contingency plans.
The natural audience is the operations or IT person who has to make the integration work, alongside the sales leader.
The trade-off is a shift away from how salespeople sell.
These posts explain architecture and resilience in clear language, but show no selling method, rep workflow or view of the buyer's decision process.
A collaboration framed around seller behaviour or a sales-feature demo would be a stretch.
One post is in Norwegian and addressed to a Norwegian-reading audience; ask for the commercial or sponsorship format before proceeding.
Five LinkedIn posts by Sebastian Karlsson appear here — four in Swedish and one in English — covering sales methodology in the CRM, AI in complex B2B sales, credibility in sales conversations, an event reflection and a lost deal.
They are the only written posts here, and they carry no publication dates.
The profile shows 6,729 followers as of 8 October 2026.
Comparison and context came from six posts by three other creators.
Gaps worth weighing: no audience-demographics export, no per-post performance data, no documented sponsorship format, rate card or inquiry route, and no other channels or longer-form work here, so this page does not establish a full account of the work.
