How it works

From a stranger's complaint to a build plan

Eureka DB turns scattered public frustration into validated, scored opportunities, then hands you the exact kit to build the winner. Here is the pipeline.

  1. 01

    Real people, real complaints

    We scan Reddit threads, app reviews, and forums for the same complaint showing up again and again. Real people asking why something doesn't exist yet, with the source saved and attributed.

  2. 02

    Patterns become opportunities

    When the same complaint shows up across dozens of posts, that's a signal. We cluster them into a single validated opportunity with a clear, specific audience you can go find.

  3. 03

    Someone's already paying for it

    Every idea comes with comparable businesses already earning, each with a confidence rating, so you know whether it's proven territory or a frontier bet before you write any code.

  4. 04

    Here's exactly how to build it

    The execution kit hands you the Claude Code prompt, the services to set up, the build order, and a plan for your first few customers.

Signals, clusters, evidence, execution

Each idea moves through the same four stages. The work compounds toward execution, where the value lives.

  1. 01Signals

    Raw, sourced complaints. A quote, a source, a permalink.

  2. 02Clusters

    Signals grouped into one opportunity with a real audience.

  3. 03Evidence

    Auditable proof: excerpts, comparable MRR, demand signals.

  4. 04Execution

    The exact kit to build and ship it. This is where the value lives.

Where the evidence comes from

We pull pain and willingness-to-pay signals from public, ToS-aware sources, then validate against comparable businesses that already make money.

Three questions, answered before you commit

Is the problem real?

We pull the actual complaints from real communities, then cluster and count them. It is evidence you can point to, not a gut feeling.

Will people pay for it?

We find businesses already solving nearby problems and label how strong the revenue proof is: High for a proven market, Adjacent for a likely crossover, Weak for a frontier bet. You will know what kind of bet you are making.

Can you actually build and ship it?

Most idea lists stop at the idea. Each one here comes with an execution kit: the Claude Code prompt, the stack, the services to set up, the build order, and a plan for your first few customers.

Data ethics

Compliant by design

We treat public sources with care. The same three principles govern every signal we store.

  1. Official APIs first

    We use official, rate-limited APIs and public pages. We do not scrape private or protected content, and we honor source terms.

  2. Attributed and minimal

    We store short, fair-use excerpts with a link back to the source. Author handles are hashed. No personal data is collected.

  3. Deletion-aware

    When upstream content is removed, our deletion-sync removes the excerpt and any identifying fields. We do not retain deleted content.

The idea is the easy part. Knowing it's worth building is the hard part.

Eureka DB does the validation work most founders skip: evidence the problem is real, proof that people pay for it, and a clear plan to build. Two ideas are open to read in full, no account needed.
