RedStripe is a MAP-monitoring platform for brands and manufacturers that answers one expensive question in real time: which retailer broke our minimum advertised price first? When a single retailer drops below MAP, the rest follow the floor down within hours - and the brand pays twice: once in eroded price integrity, and again in the price-protection rebates it owes retailers to compensate for the very price drops it failed to catch. RedStripe watches every SKU across every authorized retailer and major marketplace, flags the first-mover breach the moment it happens, and turns "we found out in next month's report" into "we got an alert in minutes." That timing difference is the whole product - and it maps directly to dollars retained.

The second pillar is third-party marketplace control. RedStripe continuously tracks third-party seller activity on Amazon, Walmart and other marketplaces - buy-box ownership, unauthorized sellers, pricing below MAP, cart-quantity games - and maintains a full seller directory (business name, address, registration/VAT, contact details) that doubles as a ready-made cease-and-desist contact list. This is built on real, substantial data: the platform migrates and normalizes a legacy dataset of ~900,000 marketplace offers and ~17,000 sellers across 14 locales/currencies, so it's solving the problem at production scale, not on a toy fixture.

It's a complete, live SaaS, not a prototype. Built end-to-end with Claude — TypeScript on Fastify, PostgreSQL 16 with Drizzle, BullMQ scrape scheduling with tiered provider fallback, a rules-based alert engine delivering to email and Telegram, and multi-tenant isolation - it already runs behind TLS at demo.redstripe.io, with authentication, the legacy data migration, and the new marketing site shipped. Claude did the heavy lifting across the stack: schema design that normalizes a sprawling per-retailer SQL Server database into one clean model, a verify-then-upgrade password migration path, and the scraper/alert architecture, all under a phase-gated plan with real verification at every step.

The market validation is concrete: demos are lined up with Garmin and Jabra - exactly the kind of premium consumer-electronics brands whose MAP discipline and rebate exposure make this a board-level concern. RedStripe addresses a known, quantified pain those brands already feel and already spend real money on, which is why the pipeline exists before the product is even fully GA. The pitch isn't "here's a clever tool" - it's "here's the leak in your pricing program, here's the first retailer who opened it, and here's what it just cost you."
