Startups often fail because of timing, not ideas. Startups.RIP is a wiki of 1,700+ YC startups that shut down or got acquired. Our AI research agent writes a detailed post-mortem (what they built, why they failed, what's changed since) and a rebuild playbook with implementation-ready technical specs you can drop straight into your AI coding agent. Every failed startup is a validated market with unfinished business. Shortcut the idea maze. Start with what almost worked.
Hey Product Hunt, I'm Oscar, the maker of Startup.RIP 👋
The best startup ideas aren't always new. They're remixes that entered a market at the right time.
Lyrebird (S17) built AI voice cloning in 2017 and folded. Years later, ElevenLabs hit $11B valuation on the same idea. Multiple YC companies tried prediction markets before regulatory changes enabled Kalshi to go mainstream. It pays to learn from startup history.
Startups.RIP is a database of 1,700+ YC startups that died or got acquired. Our AI deeply researches post-mortem for each one — what they built, why they failed, what's changed — and generates a rebuild playbook with implementation-ready specs you can drop into Claude Code, Codex, or your coding AI of choice.
As covered by Forbes: dozens of YC fintech startups that took teams of engineers years to build can now be shipped in an afternoon using AI.
The first 32 reports are free. Pro ($20/mo) unlocks everything. We're giving 25% off the Pro subscription to our first 100 supporters (use the code PHLAUNCH). We also offer a 50% BUILDER discount for anyone who builds and ships a project inspired by an idea they found on Startups.RIP.
The product is still rough around the edges, so any feedback is much appreciated. Drop a comment; I read everything.
