What they are known for

Michael Bervell is a TestParty co-founder whose LinkedIn work explains website accessibility through the practical problems ecommerce stores face.

  • Their posts focus on how source-code issues can affect shoppers using assistive technology and how the same issues may obstruct AI shopping agents.
  • They turn that subject into concrete examples: a scan of 19,581 storefronts, a discussion of compliance economics on the Honest Ecommerce podcast, and a detailed prompt for a TestParty explainer video.

Bervell connects accessibility claims to specific parts of a store and explains why those details matter.

  • In the storefront scan post, an unlabeled cart icon is not just one defect: if it sits in a shared theme, it can recur across a catalog.
  • The post also contrasts homepages with product and collection pages, where the reported failure count rises, and connects accessible controls to both screen-reader use and AI agents attempting to shop.
  • That combination makes the issue easier to picture than a general warning about compliance.
  • They also share the reasoning and materials behind the message: a podcast summary addresses the economics of demand letters and the limits of overlays, while the video post includes a complete creative prompt with four visual approaches.
  • The work offers specific ecommerce examples, arguments about root-level fixes, and reusable explanations.
  • For campaign claims, ask for the underlying data behind the reported figures.

Ideas and priorities

Across these posts, Michael Bervell treats website accessibility as a structural problem, not a cosmetic patch: fix repeated failures in the underlying theme, weigh compliance choices in practical terms, and consider how accessible site controls also affect AI shopping agents.

Fix the theme, not just the page

Bervell argues that accessibility failures often stem from shared theme components, so one faulty control can recur across an entire catalog.

Read more

That makes the theme a better place to look for fixes than treating each page as a separate problem.

In a scan covering 19,581 storefronts, Bervell says the median store broke six rules, each repeated about 5.5 times.

  • They explain that an unlabeled cart icon in a header can produce broken links throughout the catalog.
  • They also report more failures on collection and product pages than on homepages.

A cosmetic overlay is not the same as fixing the underlying code

Bervell contrasts overlay widgets with changes to a site's source code.

Read more

An apparent compliance measure may not resolve the underlying barriers and could itself be cited in a demand letter. They frame accessibility as a question of both technology and the economics of responding to legal claims.

In a recap of an Honest Ecommerce conversation, Bervell says most settlements cost $10,000–$25,000, roughly what it can cost to prove compliance. They describe demand letters naming widget providers as evidence of non-compliance, including one that listed twelve widgets, and say source-code fixes hold up better.

Read original

Accessible controls matter to AI shopping agents, too

Bervell connects accessibility for people using assistive technology with AI agents' ability to navigate a store.

Read more

They argue that both depend on the information exposed by a site's accessibility tree.

Bervell explains that a button without an accessible name can be invisible to a screen reader and to an agent trying to add a product to a cart; an unlabeled quantity field can also prevent the agent from completing checkout. They note that agentic traffic is small at present.

Start with their work

Storefront accessibility scan of 19,581 ecommerce sites

This is Bervell’s most concrete published evidence: a large scan with specific numbers.

Read more

It answers a newcomer’s first question: how widespread are ecommerce accessibility problems, and where do they occur in a store?

Bervell reports scanning 19,581 ecommerce storefronts and finding 140 clean, or 0.75% — one store in 134.

  • The rest carried 1.77 million broken elements: buttons with no name, links with no text, quantity fields with no label, and controls nested inside other controls.
  • Three findings stand out.
  • First, the problem is the theme, not the content: the median store breaks six rules and repeats each roughly 5.5 times, so one unlabeled cart icon in a header component ships across an entire catalog.
  • Second, the homepage is a store’s best page — failure counts grew about 3.9 times deeper into collection and product pages, where purchases happen.
  • Third, nobody is perfect: 27% of stores scored 90 or better, none scored 100, and the best score in the whole set was 97.
  • Bervell also argues that AI shopping agents read the same accessibility tree as a screen reader, making an unnamed button invisible both to a blind shopper and to an agent trying to add an item to a cart.
  • The cleanest stores named are Graza, OLIPOP, UNTUCKit, Liquid Death, FIGS and OLAPLEX.

For brands planning a campaign

A co-marketing webinar can open with these scan numbers and the theme-not-content framing, shifting the conversation from a vague legal worry to a specific, fixable place in a Shopify theme. The agent-readability argument gives the session a forward-looking second half beyond ADA demand letters.

$1,000 for a two-line introduction

This post shows how TestParty gets customers and how Bervell thinks about networks and trust — useful context for a partnership conversation.

Read more

Bervell offers a $1,000 Amazon gift card, with no cap, to anyone whose two-line introduction to an ecommerce brand turns into a TestParty customer.

  • The post pairs the offer with a personal story: Bervell was an intern at Harlem Capital in 2020, stayed in touch through alumni events, congratulations notes and no-agenda coffees, and four years later Harlem Capital co-led a $4M round in TestParty — the first former intern the firm had backed.
  • They cite Mark Granovetter’s 1973 paper "The Strength of Weak Ties" and its finding that over 80% of jobs found through personal contacts came from people seen only occasionally.
  • The brand-side pitch is that ADA demand letters reached 6,000+ brands in a year and 96% of top websites still fail accessibility standards.
  • TestParty is described in one line as using AI to find and fix accessibility issues in a website’s source code, with 30 million+ issues fixed and brands including Eddie Bauer, Magic Spoon and Levain Bakery.

For brands planning a campaign

Bervell works through incentive mechanics and warm introductions rather than paid media. A webinar partnership is most likely to land if it presents two audiences vouching for each other — the agency’s Shopify clients and TestParty’s DTC contacts — rather than a one-way placement.

Honest Ecommerce episode with Jason Tan

This is Bervell in conversation rather than in a written post, showing how they frame compliance economics and the overlay-widget debate for an ecommerce audience.

Read more

Summarizing the Honest Ecommerce podcast appearance with co-founder Jason Tan, Bervell lays out three points.

  • About 5,000 demand letters were filed publicly the previous year, with an estimate of 10,000 to 15,000 once private settlements are counted; most settle for $10,000 to $25,000, roughly what it costs to prove compliance, so brands pay even when they believe they are right.
  • Overlays, they argue, have become a target rather than a shield: demand letters have named widget providers by brand as evidence of non-compliance, and one listed twelve different widgets.
  • Source-code fixes hold up better — under 5% of TestParty’s active customers had received a demand letter.
  • Bervell notes that the industry extends beyond technology into policy and strategy, and links the full episode in the post.

For brands planning a campaign

These three points make ready-made webinar segments, while the overlay position directly counters agencies already selling overlay tools to clients. The named podcast offers a format template and a host to reference.

$4.4B in GMV flowing through TestParty customer sites

A quick read on scale: how much commerce runs through stores TestParty already serves, and which brands are on the list.

Read more

Bervell states that more than $4.4 billion in GMV moves through TestParty customer sites annually across 1.1 billion or more accessible sessions, which they put at roughly 1.2% of Shopify’s GMV.

  • Brands named include Claire’s, OLIPOP, Hulken, OluKai, Magic Spoon and SUKOSHI, alongside "hundreds more."
  • The post is framed as Q3 data.
  • Ask for the calculation method before relying on the figures.

For brands planning a campaign

For an agency working on Shopify, this is the most directly relevant proof point in the set — it puts the platform and the customer base in the same sentence. It can anchor a "what's at stake" segment, with the caveat that the underlying calculation is not published.

The two-minute TestParty explainer prompt, published in full

This shows Bervell’s working method: they publish the actual prompt and tool list rather than teasing a finished video.

Read more

Bervell describes creating a two-minute "Editorial Motion Graphics" explainer for TestParty in about an hour during lunch for $20, and posts the full prompt.

  • It lays out the substance — TestParty as an AI accessibility compliance platform that fixes WCAG 2.2 AA violations in source code rather than applying an overlay widget, built for Shopify and DTC brands, with 200+ customers, backed by $4M from Harlem Capital and Urban Innovation Fund plus NSF SBIR Phase I and Phase II — and four visual directions: a blind shopper in a kitchen failing with a screen reader, a crash zoom into source code rewriting itself clean, a cracked storefront window under a decorative film as the overlay-versus-root-fix metaphor, and a confetti drone flythrough for brand energy.
  • The prompt specifies camera motion, subject, lighting and film stock for each, recommends Seedance 2.0, Kling 3.0, Veo 3.1, Wan 2.7 or Sora 2, and closes by asking what other video use cases people have seen.

For brands planning a campaign

Bervell shares reusable production assets, not just opinions. A webinar could offer a shared prompt or creative pack as a giveaway, and the four visual directions provide a ready-made creative brief for the agency’s client pitches.

Ecommerce accessibility data from a 19,581-store scan

Bervell published results from a scan of 19,581 ecommerce storefronts for accessibility problems: 140 were clean (0.75%, or one store in 134), and the rest had 1.77 million broken elements.

Read more

The headline finding: failures come from themes, not content.

  • The median store breaks six rules and repeats each one about 5.5 times, so a single unlabeled cart icon can ship as dozens of broken links across a catalog.
  • Product and collection pages were 3.9 times worse than homepages.
  • No store scored 100; the top score was 97, and 27% scored 90 or better.
  • Stores named among the cleanest include Graza, OLIPOP, UNTUCKit, Liquid Death, FIGS, and OLAPLEX.

A large-sample scan reported through aggregate counts by rule and page type, with specific stores named as positive examples.

For brands planning a campaign

Offers a webinar a data-led hook an agency can reuse: a benchmark for the client's own theme, a page-type finding pointing to product pages, and named peer brands for comparison. The scan result is available to request for free, supporting a co-marketing opt-in offer.

Examples: Source 1

Compliance risk framed as a settlement-versus-fix calculation

On the Honest Ecommerce podcast with co-founder Jason Tan, Bervell put accessibility risk in financial terms: about 5,000 demand letters were filed publicly last year, with an estimated 10,000–15,000 including private settlements.

Read more

Most settle for $10,000–$25,000 — roughly the cost of proving compliance in the first place. They argue overlays have become a liability rather than a shield, citing one demand letter that named twelve widget providers as evidence of non-compliance, and say under 5% of active customers have received a demand letter.

Podcast conversation; the figures are presented as estimates based on TestParty's view of the market.

For brands planning a campaign

This is the proposed webinar's compliance-risk half, already framed as an argument an agency audience can follow: pay to settle or pay to fix. The critique of overlays offers a clear contrast for positioning source-code remediation.

Examples: Source 1

AI shopping agents and the accessibility tree

Bervell argues that AI shopping agents read a store as assistive technology does — through the accessibility tree of names, roles, and values.

Read more

A button with no accessible name is invisible both to a blind shopper and to an agent trying to add a SKU to a cart.

  • An unlabeled quantity field leaves an agent unable to complete checkout, while nested interactive controls can send it to the wrong element and prompt it to abandon.
  • They note agentic traffic is small today and frame the theme decision around whether a brand will be in the consideration set later.

A parallel drawn from the scan findings, not a separate measurement of agent behavior.

For brands planning a campaign

A forward-looking segment connects compliance work to agentic commerce, broadening the webinar's appeal beyond legal risk for DTC brands weighing where to spend.

Examples: Source 1

Warm introductions as a growth channel

Bervell recounts staying in touch after a Harlem Capital internship and later closing a $4M round co-led by the firm, which they describe as the first time it backed a former intern.

Read more

They cite Mark Granovetter's weak-ties research, which found that over 80% of jobs secured through personal contacts came from people seen only occasionally.

  • The post turns that into a standing offer: $1,000 for a two-line introduction to an ecommerce brand that becomes a TestParty customer, with no forms and no cap.
  • It also describes TestParty as AI that finds and fixes accessibility issues in website source code, with 30 million-plus issues fixed for brands including Eddie Bauer, Magic Spoon, and Levain Bakery.

A personal narrative leading into a commercial offer, supported by a cited social-science paper.

For brands planning a campaign

Shows a simple incentive model an agency partner could adapt for webinar promotion. The story-led, direct offer also gives a sense of how Bervell might carry a live session.

Examples: Source 1

AI video production, demonstrated with a published prompt

Bervell described producing a two-minute faceless explainer for TestParty, from prompt to finished video in about an hour for $20, using an editorial motion-graphics style.

Read more

They published the full prompt, including four visual directions: a screen-reader user failing on a store page, source code rewriting itself, a cracked storefront window compared with a taped-over fix, and a celebratory office scene. The post recommends Seedance 2.0, Kling 3.0, Veo 3.1, Wan 2.7, or Sora 2 and asks what other video use cases readers have seen.

For brands planning a campaign

A topic beyond compliance that shows how Bervell tests and explains AI creative workflows. It could provide co-marketing assets or a lighter companion strand if the accessibility angle needs one.

Examples: Source 1

Company positioning: customers, funding, and reach

Across the posts, TestParty is described as an AI accessibility compliance platform for Shopify and DTC ecommerce that fixes WCAG 2.2 AA violations in source code rather than through an overlay widget.

Read more

The company has 200+ customers and funding from Harlem Capital and Urban Innovation Fund, plus NSF SBIR Phase I and Phase II.

  • A quarter-end post states that more than $4.4 billion in GMV flows through customer sites annually across 1.1+ billion accessible sessions, about 1.2% of Shopify's GMV.
  • Named brands include Claire's, OLIPOP, Hulken, OluKai, Magic Spoon, and SUKOSHI.

Irum does hands-on accessibility work and frames it for site owners much as Bervell does: audits, WCAG 2.2 AA remediation, keyboard navigation, forms, links, buttons, and contrast fixes, presented alongside the commercial risk of ignoring accessibility.

Read more

Both turn compliance language into a service website owners can buy.

Irum works across WordPress and small-business, law-firm, and professional sites, pairing accessibility with SEO and AI automation services. Bervell works at ecommerce scale around Shopify storefronts, publishes aggregate scan data rather than client-level project descriptions, and argues from the economics of legal claims against a platform that fixes source code.

Ayinde Rudolph, Ed.D.

Rudolph treats WCAG 2.2 AA as a starting design choice rather than an afterthought, much as Bervell argues accessibility belongs in the theme and source code, not in a later patch.

Read more

Both write about accessibility decisions as engineering commitments, with public detail on baselines, contrast ratios, focus indicators, screen-reader order, and crisis-handling rules.

Rudolph applies this standard to an AI product for education and mental-health support, writing about duty of care, privacy in crisis situations, and notification rules for minors. Bervell applies it to ecommerce storefronts, measures failures across thousands of shops, and centers the legal and conversion costs for DTC brands.

Gatenby reads Shopify platform changes for their accessibility and compliance consequences, naming the European Accessibility Act and warning that an AI-assisted redesign can strip alt text, keyboard access, and structured data.

Gatenby works agency-side on design, brand, and storefront projects — including menswear and heritage retail — and evaluates tools from a client-delivery point of view. Bervell sells the remediation platform itself, publishes scan statistics across tens of thousands of stores, and speaks mainly to legal risk and agent readability.

The available audience number is a LinkedIn follower count of 13,952, observed on 11 October 2026.

  • Across five full posts published between 3 August and 1 October 2026, Michael Bervell writes directly to store owners and ecommerce operators (“if you own a storefront”), reports an ADA-risk scan across 19,581 storefronts, and names Graza, OLIPOP, UNTUCKit, Liquid Death, FIGS, OLAPLEX, Claire’s, and Magic Spoon among customers or clean-scan examples.
  • A 27 August 2026 appearance on the Honest Ecommerce podcast with Chase Clymer places the topic in an ecommerce-operator and agency conversation.
  • A paid-introduction offer aimed at Shopify brands also suggests that network is reachable through the posts.
  • Before committing, ask the creator or TestParty for recent post-level results on comparable compliance and DTC ecommerce posts (impressions, unique viewers, comments), an industry-and-role or seniority breakdown from a platform export or audience survey, and registration-to-attendance numbers from past webinars.

Partnership options

Michael Bervell's partnerships run through TestParty, the website accessibility company they co-founded, rather than through a personal creator sponsorship program.

Read more

The five LinkedIn posts contain no media kit, rate card, or stated sponsorship policy, so brands should start with TestParty rather than a creator booking process.

  • The posts show the shape of existing collaborations: Bervell and co-founder Jason Tan appeared together as guests on the Honest Ecommerce podcast; TestParty publishes original ecommerce accessibility research and markets with it directly; and TestParty runs an open referral incentive paying $1,000 for a two-line introduction that turns into a customer.
  • A co-marketing webinar on ADA compliance and source-code fixes could take the form of a joint session built around TestParty's own scan data, with both founders available.
  • Ask TestParty directly for commercial terms and the right partnership contact.

Podcast and webinar guest appearances

Buyer requirement

Plan for a two-person appearance: the Honest Ecommerce episode featured Bervell with co-founder Jason Tan, so a webinar or podcast slot will likely involve both.

  • Come with a defined topic, audience, and date rather than a general invitation.
  • Treat a co-hosted webinar as something the brand proposes; no event or webinar format is advertised publicly.

Co-marketing built on TestParty's accessibility research

Buyer requirement

Work from TestParty's published findings rather than asking for new research.

  • The scan of 19,581 ecommerce storefronts, the count of 1.77 million broken elements, and the claim that more than $4.4 billion in GMV flows through TestParty customer sites are already public and are the numbers the company markets with.
  • A partner should bring its own audience and distribution to add reach, since the data itself is not an exclusive asset.

Referral incentive for introductions

Buyer requirement

Understand the disclosed incentive before discussing terms.

  • TestParty offers a $1,000 Amazon gift card for an introduction that becomes a paying customer, with no stated cap and no forms.
  • The offer targets individuals who can make an introduction, not corporate partners, and no equivalent brand-partner rate or commission is published.
  • Ask TestParty what commercial terms a co-marketing arrangement carries.

Fast in-house video and content production

Buyer requirement

Bring the substance—product details, audiences, and the points the piece must make—and expect a produced video back quickly.

  • Bervell described creating a two-minute TestParty explainer prompt-to-video in about an hour for roughly $20 using AI video tools, and published the prompt.
  • A partner supplying the campaign message can plan around that turnaround, but should confirm output quality and review terms first.
Sources for this section

Campaign fit

A campaign to shortlist

Strong fit: a Shopify-focused ecommerce agency wants a co-marketing webinar on ADA compliance risk and source-code accessibility fixes for direct-to-consumer brands.

Read more

Bervell’s posts address ecommerce operators directly and offer concrete material for the session: a reported scan of 19,581 storefronts, examples of recurring theme-level failures, and a comparison of overlays with source-code fixes.

  • Their summary of an Honest Ecommerce appearance also frames demand-letter exposure in business terms.
  • Posts about partnerships support proposing a joint webinar, potentially with co-founder Jason Tan.
  • The agency should bring its own audience and distribution, confirm who will appear and which claims can be substantiated, and ask TestParty about commercial terms and how many followers work at Shopify or DTC brands; the available audience figure is only a LinkedIn account count.

When to choose a specialist

Weak fit: a consumer apparel brand wants a paid lifestyle endorsement aimed at fashion shoppers, with guaranteed reach among a defined age or geographic group.

Read more

The posts focus on TestParty, ecommerce accessibility, fundraising relationships, and AI-assisted video production—not fashion or consumer lifestyle.

  • The available follower count does not establish audience demographics, and the posts provide no engagement results, sponsorship policy, rate card, or indication of a personal endorsement program.
  • A brand seeking a placement with a defined age or geographic audience should choose a creator whose audience and past work match that need, or ask Bervell for audience demographics, performance information, and sponsorship terms before proceeding.
A worked campaign example

For the agency webinar, use the title “Where Shopify accessibility problems hide: themes, product pages, and the limits of overlays.”

  • Open with their reported scan finding that only 140 of 19,581 stores were clean, then show how an unlabeled cart control in a shared theme can recur across many pages.
  • Move to their reported finding that failures rose on collection and product pages, and ask the agency to bring one anonymized client example for a practical walkthrough.
  • Close by separating accessibility fixes from claims about legal outcomes: their podcast summary discusses demand letters and overlays, so present those as their account, not legal advice or independently verified results.
  • Offer attendees a follow-up checklist or scan discussion, subject to TestParty confirming what it can provide.
  • The agency supplies promotion and registrations; Bervell and TestParty supply the technical perspective and confirm speakers, data, and commercial terms before the invitation goes live.

Who else to consider

Claire Gatenby

Pick Gatenby when the webinar audience is Shopify merchants and the agency wants a practitioner who edits themes and comments publicly on Shopify product changes.

Read more

Gatenby's post on the Shopify Canvas demo works through a concrete release: Canvas lays out a store in one workspace; a theme edited in Canvas stops receiving theme updates; and Sidekick checks that code works and looks right, but not whether it is accessible.

  • Gatenby ties that to the European Accessibility Act, which has applied since June 2025 to many stores selling to EU customers, and to whether AI shopping tools can still read a store's content.
  • A second post about taking on a Harrogate menswear client shows how Gatenby frames a merchant relationship around why customers buy.
  • For a store-owner audience, that is closer to their daily decisions than a compliance scan.

The tradeoff is reach and evidence type.

  • Gatenby writes about individual storefront projects and product commentary.
  • The posts here contain no scan across thousands of stores, demand-letter or settlement figures, or product that fixes accessibility in source code.
  • For a campaign explaining the scale of the compliance problem across merchants or what a remediation product actually does, Bervell's posts carry that material; Gatenby's do not.

Examples: Source 1 · Source 2

Sobia Irum

Choose Irum when the deliverable is a hands-on accessibility audit and remediation plan for WordPress-based sites, including law firms and professional services.

Irum's post lists the services in detail: website accessibility audits, WCAG-focused improvements, WordPress accessibility remediation, keyboard navigation fixes, form, link, button and heading structure fixes, contrast and readability work, and manual testing.

  • The post frames accessibility as a business problem as much as a legal one.
  • A second post describes building a Fluent Forms to Clio Grow intake integration for law firms, pointing to a legal-sector client base.
  • A webinar for a legal or professional-services audience that ends with an actual site review suits this evidence better than a merchant-scale compliance scan.

The tradeoff is that the work involves service delivery for individual clients, not ecommerce research or a software product.

  • The posts here contain no storefront scan data, figures on demand letters or settlements, or coverage of Shopify themes or DTC brands.
  • An agency selling Shopify work to merchants would need to supply the ecommerce framing itself.

Rudolph's posts describe Jean OS launching with WCAG 2.2 AA as a foundational design choice, detailing contrast and focus indicators, minimum target sizes, screen reader and Braille reading order, cognitive and dyslexia-friendly design, and reduced-motion and voice-control support.

  • A second post sets out a pledged crisis response: staying present with someone in distress, logging only a category and timestamp, and never routing an adult's distress signal to an employer.
  • For a session aimed at teams building assistive or educational AI, that mix of baseline specification and duty-of-care policy is the closer comparison.

The tradeoff is the buyer and setting.

  • Rudolph's material is about AI product design and responsible-AI policy in education and health, not ecommerce compliance.
  • It has no storefront or theme examples, demand-letter economics, or merchant-facing remediation offer, so a DTC-oriented webinar would need to translate the framework rather than reuse it directly.

Research methodology

  • This page draws on five full LinkedIn posts published by Michael Bervell.
  • The posts cover TestParty's work: a reported scan of 19,581 ecommerce storefronts, a summary of a guest appearance on the Honest Ecommerce podcast, funding and customer figures, a referral offer, and a prompt for an AI-generated TestParty explainer video.
  • Every example and figure on the page comes from those posts or from the comparison posts included in the similar-creators section, and figures Bervell reports are attributed rather than presented as independently verified.
  • The posts carry no publication dates, and they do not include the underlying scan data, the full podcast episode, or information about any books, shows, or earlier career work, so the page does not claim them.
  • Similar-creator notes draw on two posts each for three other creators; those are not full reviews of their work, and no audience measurement was used to build the topic tags.
  • Notes on individual sections describe the source types and scope behind each one.
