Give away a WCAG checker everyone uses; sell organizations continuous whole-site accessibility monitoring.

Will it work? · our read
Rode the mandate. But the scan is now free everywhere (axe, Lighthouse, AI). Silktide must be the compliance system of record, not just the checker — or better-funded Siteimprove wins.
01How the money moves
Give away a free WCAG checker devs use worldwide
Regulation (EAA, ADA) forces orgs to prove compliance
They buy annual whole-site monitoring

04The key move
Give away the scanner
The free scanner (Sitescore, 2004; later a WCAG checker devs use everywhere) went viral on TV. It became a 20-year lead machine — so when the EAA forced compliance in 2025, Silktide sat atop the funnel.
fact
The counter-intuitive move
Free tools are cheap to copy — accessiBe and AudioEye give away scanners too, and axe is open source. The viral moment was a one-time gift, not a repeatable moat.

05Where the moat is
What defends Silktide is distribution and trust, not the scan itself:
20-year accessibility brand + Silktide IndexFree checker = massive top-of-funnelWhole-site monitoring, not one-page scansPublic-sector trust: NHS, Oxford, gov
06How it diesmedium confidence
If checking becomes a free browser/AI feature, the paid scan-every-page layer commoditizes. Durable value — ongoing governance plus human audits — is Siteimprove's better-funded turf. our read
Show evidence · counter
Evidence: First EAA lawsuits filed in France (Nov 2025); a court ordered Carrefour to fix its site and app (June 2026) — enforcement is real, not hype.
Counter: But regulation keeps ratcheting — WCAG updates, fresh lawsuits, US ADA plus EU EAA — so compliance urgency recurs. And Silktide bundles content, UX, and SEO, not just accessibility, which is stickier than a checker.

Would it work for you?
Do you have a distribution wedge before the deadline hits — a free tool people already use?
Silktide's edge was 20 years of free-tool reach, not the scanner. We don't score you — you answer.
🚀Use it as a launchpada prompt for your own AI
Copy → paste into your AI → then develop it freely in the conversation.
You are a sharp, honest startup strategist. Use the proven case below as a launchpad for MY idea — help me find my own angle, not copy it. <my_profile> Domain I know: [your domain] My unfair advantage (access/audience): [your edge] Interests: [your interests] Resources & goal: [your resources] · [your goal] </my_profile> <case name="Silktide" model="saas"> What it does: A free WCAG checker on top; annual whole-site accessibility monitoring underneath. Why it won (moat): Distribution and public-sector trust built over 20 years — not the scan tech. Weakest axis (CENTS): The scan is commoditized by axe, Lighthouse, and AI. How it could die: Checking becoming a free browser/AI feature, with Siteimprove out-spending the governance layer, erodes it. </case> <task> Be a skeptical operator, not a cheerleader. No generic startup platitudes. If my angle is weak, say so plainly. First, a reality check: markets like this mostly fail. State the honest base rate (how crowded/hard is this?) and the ONE specific thing that would have to be true for ME to be the exception — grounded in my profile above. Then a compact table: - Fit — does this pattern suit my edge, or fight my gap? - Angle — my sharpest differentiation vs Silktide (concrete, not "better UX") - Distribution — exactly where my first 100 users come from (this is the hardest part — be specific, not "content marketing") - Risk — its "how it dies" (above) in MY situation Finish with one line: "The single thing to do next." Use only the facts above; if data is thin, say so — never invent numbers. Then stay with me and go deeper on whatever I ask — tech stack, rough cost & time, the smallest MVP to test, pricing, or timing. </task>

Silktide — company history: Sitescore free tool (2004), dropping web design (2010), pivot to accessibility, Silktide Index (2020).Latka — Silktide: revenue about $3M (2024), up from $1.6M (2021), about 27 staff, bootstrapped (third-party estimate).European Commission — EAA in effect 28 Jun 2025: accessibility mandatory across all 27 EU states, fines up to 4% of revenue.Silktide — free Accessibility Checker: 200+ WCAG 2.2 checks, screen-reader and disability simulators (the free top-of-funnel).Silktide — accessibility solution: whole-site automated testing; customers include NHS, University of Oxford, eBay, Michigan State.
Revenue (about $3M, 2024) is a third-party estimate from Latka, not a first-party disclosure — Silktide is a private UK company that publishes no figures, so it is marked EST / not independently confirmed. The founder, 2001 bootstrapping, free-scanner-to-platform history, customers (NHS, Oxford, eBay, Michigan State), and the regulation timeline (EU Web Accessibility Directive; EAA in force 28 Jun 2025, fines up to 4% of revenue; French lawsuits Nov 2025; Carrefour ordered June 2026) are documented on first-party or official sources. The 'give away the scanner' story is on Silktide's own history page; the read that this is (or is not) a repeatable moat is [our inference]. We never score you.
