What changed
HYPOTHESIS: ARCore/ARKit depth + geospatial anchoring now measure real-world features at claimed sub-meter accuracy without custom positioning infrastructure (FACT per Android XR Geospatial API post), and sub-$300 AR glasses (XREAL) lower the display bar. INFERENCE: this puts hands-free spatial measurement in reach of a solo builder and a non-technical end user.
Why now
FACT (Guardian): a wave of ADA physical-access lawsuits is actively frustrating US cafe/shop owners. INFERENCE: fear plus a newly-cheap measurement capability creates a discretionary window for a pre-emptive audit tool.
Converging signals
Three signals meet: ADA-lawsuit pain (complaint), sub-meter ARCore geospatial measurement (android), and a $300 AR display (wearable). This is a pain × cheap-capability quick-win shape, NOT a forced-filer mandate — no one is compelled to buy this.
Customer pain
FACT: owners are being sued over physical-access defects they didn't know they had. They face demand letters, statutory damages (CA Unruh Act = $4,000/violation), and expensive reactive remediation. HYPOTHESIS: they'd pay to know their risk before the letter.
Who pays
Small brick-and-mortar owners in high-litigation states (CA, NY, FL) buying a $99–299 self-audit; secondarily ADA remediation contractors and CASp inspectors who might license a triage tool to pre-qualify site visits.
Solved today
Free ADA.gov checklists and tape-measure self-surveys; paid CASp (Certified Access Specialist) inspections in CA; remediation contractors; ADA-audit consultancies. The self-help path is free but tedious and non-authoritative.
Why current solutions are bad
Free checklists require manual measuring and don't produce a defensible record; CASp inspections cost hundreds-to-thousands and require scheduling. GAP: nothing gives a fast, cheap, photo+measurement first-pass triage.
Proposed product
Phone-first app (glasses optional): codified ADA dimensional checklist, user pans each feature, app snaps photo + AR measurement + geotag, flags likely pass/fail, exports a branded PDF triage report with a clear 'screening tool, not a legal certification' disclaimer.
MVP version
iOS ARKit build covering the 6–8 highest-frequency litigation items (36" clear width, 1:12 ramp slope, 34" counter height, door thresholds/clearance, parking, restroom clearances). Ship the KILL TEST first: measure 20 known features vs tape/CASp and publish the false-negative rate.
30-day build
Run the accuracy validation study (10 compliant / 10 non-compliant features, app vs certified inspector). If borderline false-negative rate is material, pivot to 'flag for professional review' framing rather than pass/fail. Codify checklist with an ADA-access attorney's review.
60-day build
Build the guided walk-through UX + branded PDF export. Recruit 5–10 beta owners in CA via local business associations. Line up 1–2 CASp inspectors as licensing/white-label pilots.
90-day revenue plan
Charge $99–199 per audit or $29/mo monitoring; sell direct via small-business Facebook groups, chambers of commerce, and CASp/contractor white-label. Target first revenue from the contractor-licensing channel, which is more reachable than fragmented owners.
Distribution path
Hard: scared owners are fragmented and low-trust. Best wedge is B2B2C — license to CASp inspectors and remediation contractors who already have the buyers and the credibility the app lacks. Direct-to-owner via associations is secondary.
Pricing hypothesis
$99–299 one-time self-audit; $29–49/mo for re-scan/monitoring; per-seat/white-label license to inspectors and contractors.
Technical difficulty
HIGH and load-bearing: consumer AR depth accuracy on inch-level ADA tolerances and small slope deltas is the make-or-break. A material false-negative rate makes the product worse than useless AND legally dangerous.
Legal / regulatory risk
SIGNIFICANT: telling an owner they are 'compliant' when they are not invites reliance-based liability and undercuts the value prop. 'Courtroom-grade' is undeliverable by consumer AR — must be positioned as a screening/triage aid, not a legal certification. CASp certification (CA) is a licensed credential the tool cannot replicate.
Platform dependency
Low — no government portal, no app-store deplatform risk beyond normal iOS/Android review. Depends on ARKit/ARCore APIs.
Founder fit
MODERATE (5): real pain, public-records/compliance flavor, and AI-assisted build all fit, but this is NOT his proven government-portal forced-filer shape, and the AR/spatial-accuracy engineering is outside his core edge and carries the highest technical risk of the pattern.
Breakout potential
Moderate: if accuracy clears the bar, replicate across 50 states and expand to fire-code/OSHA/insurance pre-inspection walk-throughs (founder's fire-service background is a real adjacency here).
Final recommendation
REVISIT / CONDITIONAL. Do not build 'courtroom-grade' — that claim is undeliverable and legally risky. Only proceed if the 30-day accuracy validation passes; if so, ship as a professional-facing triage/white-label tool for CASp inspectors and remediation contractors (reframe away from direct-to-owner compliance assurance). If accuracy fails, kill it.
Next action
Run the KILL TEST first: build a throwaway ARKit measurement harness, measure 20 features of known ADA status against a tape measure and (ideally) a CASp inspector, and compute the borderline false-negative rate before writing any product code.
