Overview

What Startup Idea Validator does.

Most founders spend weeks validating an idea by asking friends and reading generic advice, and still build the wrong thing. This skill collapses validation into one prompt: paste a one-line idea from any industry or market and get back a complete, decision-ready validation report the same day.

The report comes as six cards: a weighted market score (1-10) with an explicit rubric and verdict bands (build / de-risk / pivot / kill), a 3-tier competitor scan covering direct and indirect competitors plus the status quo with a positioning sentence that beats them, three ranked monetization models with the math to your first $1k/month, a disciplined MVP scope listing 5 features to build and 10 NOT to build yet, a channel-specific launch strategy with a day 1 / week 1 / month 1 sequence, and 5 paste-ready viral hooks to test demand before you write a line of code.

It also includes the parts founders always skip: a risk register with explicit kill criteria, and a 7-day validation sprint you can run for under $100. Works with Claude (Sonnet 4.5+) and ChatGPT (GPT-5+).

Who it's for

Aspiring founders sitting on an idea, indie hackers choosing their next build, side-hustlers testing demand before quitting their job, and agencies or consultants vetting client ventures before committing resources.

In depth

Why a Claude skill beats a prompt template.

A copy-paste prompt runs one static pass and stops. A skill is a bundled program — instructions, examples, and a workflow Claude runs as a unit: it asks for the right input, applies the same pattern every time, and returns the structured outputs above.

FAQ

Common questions.

What do I need to provide as input?

One line describing the idea is enough — for example 'a meal-planning app for shift workers'. Any extra context you add about target market, pricing thoughts or your own skills sharpens the scoring and the launch plan, but nothing beyond the one-liner is required.

What does the market score actually measure?

It is a weighted 1-10 score with an explicit rubric covering factors like market size, urgency of the problem, willingness to pay and competitive pressure. The score maps to verdict bands — build, de-risk, pivot or kill — so you get a recommendation, not just a number.

Will it just tell me my idea is great?

No. The report includes a risk register with explicit kill criteria, and the verdict bands include pivot and kill outcomes. The MVP scope is deliberately disciplined: it lists 10 things NOT to build yet alongside the 5 to build.

Does it work outside tech startups?

Yes. The idea is a runtime input, so it works for any industry and any market — physical products, local services, B2B software, content businesses. The competitor scan and monetization models adapt to the type of business you describe.

What is the 7-day validation sprint?

A concrete day-by-day plan to test real demand for under $100 before you build anything — using the viral hooks from the report to measure interest, with the kill criteria telling you when to stop or double down.
