GTM Teardown
Paste a startup's website. In about a minute you get a one-page go-to-market audit: who it's for, how the positioning lands, three outbound angles, and the first 90 days I'd run there.
Your first teardown is free, no email needed. Two more are free with a verified email. Everything in the teardown cites the page it came from. If something isn't on the site, it says so instead of guessing.
