Why outsource the verdict

Building got cheap. Choosing what to build did not.

A chatbot will tell you your idea is promising. We check every claim against a source, put numbers on the market and the economics, and a person signs off on the verdict, including when it is “don’t build”.

Questions

Isn’t this what ChatGPT does for $20?

A chatbot gives you an answer. We give you a decision you can defend: research in separate steps against live web results, a source check that removes anything not actually retrieved, numbers with their formulas, and an analyst who signs off on the verdict.

Will you tell me not to build it?

If the evidence says so, yes. The verdict is build, test first, or don’t build. Saving you months on the wrong product is the point.

What kinds of ideas do you take?

Software, AI tools, marketplaces and apps are our core. We also take hardware, health, fintech and physical products; for those we tell you upfront when a specialist review is needed.

I’m an investor or run an accelerator. Does this work for us?

Yes. Choose your role in the form and the report is written for an evaluator, with more weight on defensibility, AI risk and the team. For a whole cohort, choose “Talk to us”.

Who sees my idea?

The lead analyst, and an AI model through a paid API that reads your answers and documents to draft the research. Notes you mark confidential never go to the AI step. Your files are deleted 30 days after delivery.

How do I pay?

After you submit, you see payment details and your private project page. Research starts as soon as payment is confirmed.

Ten minutes of questions. 3 days to a verdict.

Tell us about the idea and what worries you most. We answer that worry directly on page one.
