CheckFa.st

Most startup ideas die not because they're bad, but because founders spend months validating them the hard way — interviews, surveys, and gut feelings. CheckFa.st cuts that down to minutes. It evaluates your product idea's market demand and financial viability using real Google Search data, giving you an instant, data-backed analysis without the guesswork.

You get the metrics that actually matter: Total Addressable Market (TAM), Customer Acquisition Cost (CAC), Lifetime Value (LTV), and a full Profit & Loss statement — all generated from live search data in the time it takes to make a coffee. If you're serious about building something people actually want, CheckFa.st helps you find out before you've burned weeks on the wrong idea.
