Preuve AI is a startup validation platform built on compound AI architecture. 10 specialized agents simultaneously scan 40+ live sources to analyze market size, competitors, community signals, and go-to-market strategy. Unlike single-model tools, Preuve cross-validates across multiple LLMs and uses RAG to ground every insight in sourced data. It delivers a 13-section report covering viability scoring, competitor mapping with pricing, financial projections, and improvement suggestions. Key outputs: TAM/SAM/SOM with citations, up to 15 competitors with funding and pricing data, community signals from Reddit/HN/Product Hunt, risk assessment, and AI pivot recommendations. Every claim links to its source. Free scan available. Founder Report $29 one-time. Radar subscriptions from $9/mo for ongoing monitoring.
