Compliance QA workspace for ad agencies, not single brands

What to build

A multi-brand compliance workspace for marketing agencies and freelance compliance consultants that crawls client Shopify/Replo storefronts plus review widgets (Judge.me, Yotpo) to flag FDA/FTC disease-claim and Meta ad-policy violations, and auto-drafts compliant structure/function-claim rewrites for each flagged page.

A single-brand SaaS version of this compliance auditor failed because individual DTC supplement founders weren't a durable buyer, but the same crawler and claim-detection logic can be repackaged as a per-brand-priced workspace for agencies and consultants who already manage compliance across many small health and wellness clients.

Demand

Agencies and freelance consultants running ad accounts for multiple small supplement, wellness, and skincare brands face recurring FDA/FTC/Meta compliance risk across every client site at once, and need a tool that scales per-brand rather than a subscription built for one founder.

Stack

• Playwright for page/DOM crawling
• OpenAI API for claim classification and rewrite generation
• Shopify Admin API
• Judge.me API
• Yotpo API
• Supabase (multi-tenant workspace + auth)
• Stripe (per-brand/per-audit billing)

Solo + AI difficulty

The crawler and rewrite-generation pieces are straightforward for one person with AI (Playwright + an LLM prompt library of FDA structure/function vs. disease-claim examples), reachable in 2-4 weeks; the hard part is building reliable Shopify/Replo theme-section parsing and Judge.me/Yotpo review-widget scraping that doesn't produce false positives, plus the multi-tenant agency workspace (client switching, per-brand reports, roles) which adds another 2-3 weeks before it's sellable.

Entry threshold

Buildable solo with a Python scraper, BeautifulSoup, and a structured-output LLM call; the technical lift is small, but the real barrier is distribution into ad agencies and earning enough trust to get audit access to client stores.

Counter-signals & risks

• Review widgets like Judge.me and Yotpo surface user-generated content, and FTC/FDA enforcement against brands for customer-submitted disease claims in reviews is legally nuanced and less-tested, so auto-flagging review content may overstate real compliance risk.

• Agencies managing many small health brands often run on thin margins and are price-sensitive, which could make per-brand or per-audit pricing harder to scale than assumed, especially with frequent client-roster churn.

• This is a single founder's unverified narrative with no independent validation of agency-side demand or of the tool's actual claim-detection accuracy.
