Free tool for startup idea validation
If you've ever read Jason Cohen's writing on startup viability, you know it's a great framework for quickly evaluating a startup idea.
I kept coming back to it every time I started something new, so with his permission I turned it into a simple free web tool — mostly for myself, but figured others might find it useful too.
There's also a second tab where you can log conversations with potential customers and track what you're actually hearing. Keeps you honest.
Free, no signup, no trackers. Your input stays on your device.
Have fun validating!
