AI will happily generate a thousand startup ideas. It can't tell you which one people will actually pay for. The Eureka Database is a library of ideas mined from real complaints on Reddit, reviews, and forums. Every idea comes with the receipts: who wants it, who's already profitable, and a working demo. Connect over MCP and your AI agent pulls the full build spec for any saved idea: the problem, the stack, the schema, even the design taste, no prompt engineering needed.
Hey Product Hunt! Jeremy here, founder of The Eureka Database.
Over a billion people visit Reddit every month, across 100,000+ active communities. A huge share of what they post is people describing problems they'd pay to fix, asking for tools that don't exist, and sharing the workarounds they've hacked together. It's the biggest pile of unfiltered demand on the internet, and almost nobody mines it.
For years my process for picking what to build was embarrassing. A shower thought, a hit of excitement, a weekend of building, then a launch to nobody. I was good at building and bad at knowing whether anyone actually wanted the thing. AI only made it worse. I could ship a polished product in a weekend, which mostly meant I could waste weekends faster.
So I built The Eureka Database.
It reads through that Reddit firehose, pulls the complaints that keep repeating, and researches each one into a real idea, with the original threads, competitors already making money, a market estimate, and a working demo.
Then it hands the whole thing to Claude Code through our MCP server. The idea, the spec, and design references from repos like Magic UI load straight into your editor, and a shared workspace keeps the build from scattering across ten tabs. It does the prompt engineering for you.
There's co-founder matching if you don't want to build alone, and an investor list for later.
Lifetime access is one payment, so please use code "PH50" for 50% off for the launch! Expires July 19th, 11:59pm EDT.
Happy to answer anything in the comments, and I'd love to hear where it misses.
— Jeremy, The Eureka Database

Who hunted The Eureka Database?
The Eureka Database was hunted by Jeremy Galang. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
