FounderPal tells you if people want your idea. We tell you if you can make money from it — built for founders who build, not marketers.
Is my idea any good?
Honest business viability analysis for technical founders.
No fluff. No email. No login.
“If you can't tell me your cost per user per month, your input/output token ratio, and your blended model cost, you're flying blind.”

How it works
Real analysis, not cheerleading
Powered by Claude Sonnet 4.6. The prompt is designed to be brutally honest — it scores viability, sizes the market, and calls out risks. No encouragement bias.
AI cost modelling
Toggle AI mode and we calculate real token costs — input/output ratios, cost per query, and monthly burn at 100, 1k, and 10k users. The maths most founders skip.
