Validate before you build - Product Idea Demand Check
cosmok · 2026-06-17 · via Show HN

The Fastest Demand Validator

Keywords in. Clear go or kill decision out.

18,400 monthly searches across 6 buyer terms

Weighted CPC $3.20

Break-even conversion 2.8%

Yes — worth building Break-even is achievable at realistic capture and conversion rates.

Search demand Volume, competition, CPC, and close variants in one report.

CAC scenarios Model acquisition cost across conversion assumptions.

Market sizing Estimate reachable visits, customers, revenue, and profit.

Shareable outputs Reports, XLSX exports, and protected sharing on Gold.

Live search volume, CPC, and competition data from Google Ads.

The decision layer

Designed for the moment before a roadmap turns expensive.

Product ideas usually fail in the gap between enthusiasm and evidence. This gives founders, marketers, and advisors a fast outside-in read on demand, pricing room, and acquisition risk.

Demand Which customer searches show real volume, intent, and competition.

CAC What click costs imply at 0.5%, 1%, 2%, 5%, and 10% conversion.

Margin Whether price or LTV leaves enough room after variable and fixed costs.

Next move A plain recommendation for whether the idea deserves deeper validation.

I had three ideas I thought were great. The report killed two in an afternoon and sharpened the third. It saved me months of building the wrong thing.

Workflow

From rough customer language to a report you can defend.

Use the words customers might search, not polished strategy language. The report helps you decide what to research next, which terms look promising, and which assumptions need pressure testing.

Enter customer searches

Add keywords manually or use guided generation to create a stronger starting set.

Add economics

Include expected price or LTV, variable cost, fixed cost, and target country.

Review demand and CAC

Compare volume, CPC, competition, conversion scenarios, and break-even thresholds.

Share the report

Export, revisit reports, and use protected sharing on Gold when the audience is external.

Use cases

Built for the decisions you're already making.

Founders validate ideas. Agencies win clients. Freelancers prove they've done the homework. Product teams prioritize with data. See how each role uses the same report.

Pricing

Three tiers for different levels of validation.

Free is for a first signal. Bronze is for comparing a few directions. Gold is for deeper research and external sharing.
