Founder validation
Validate a startup idea before building.
Test demand and build a real list before writing code, hiring, raising, or spending months on a product the market may not want.
What founders can test
Early founders need evidence before momentum turns into sunk cost. Litmus helps convert raw startup ideas into market-facing experiments.
- Customer segment, pain intensity, and positioning.
- Offer, pricing, packaging, and access model.
- Landing page promises and acquisition channels.
- Waitlist, demo, preorder, or paid-interest signals.
Decisions
Use evidence to choose the next move
Build
The signal is strong enough to justify product investment.
Iterate
The audience or promise is promising, but the offer needs another test.
Kill
The signal is too weak to justify more time on the current bet.
Prove demand before code.
Litmus helps founders test whether the market wants the idea before the build starts.
