Investors and accelerators want evidence of demand, not anecdotes from ten friends. WouldTheyBuy gives you a research-backed buying-intent signal built on the methodology from Semantic Similarity Rating (arXiv:2510.08338, Maier et al., 2024). In 60 seconds you get a purchase-intent score on a 5-point scale with demographic-level breakdowns showing exactly which segments want your product most. Use it for startup idea validation, to prove market demand to investors, or to strengthen your YC application with real evidence. Compare positioning, pricing, and audience angles side by side and put a concrete data point in your pitch deck before you ask for money.

Frequently asked questions
Can I put WouldTheyBuy results in my pitch deck?+
Yes. Every result gets a shareable link, and the purchase-intent score and demographic breakdowns are designed to be presentation-ready. Drop them into your deck to show investors real demand evidence.
How is this different from customer discovery interviews?+
Interviews are qualitative and take weeks. WouldTheyBuy gives you a quantitative purchase-intent signal in 60 seconds using peer-reviewed methodology (arXiv:2510.08338). Use it alongside interviews — not instead of them.
Can I use this for my YC application?+
Yes. A research-backed purchase-intent score is a stronger signal than 'I talked to 10 friends.' Run a test and include the results as evidence of demand.
Is WouldTheyBuy free?+
Yes, completely free. No signup, no credit card, no limits. Test as many ideas as you need.
What data do I need to get started?+
Just a one-sentence description of your product idea and a target price. No business plan, no customer list, no prior research.
