In their own words, as submitted to SaaSHub.

Killgate is an anti-hype decision tool for founders. Before you spend months building, it stress-tests your idea, shows what it still needs to prove, and lays out the evidence so you can decide to build, change course, or walk away. Made for solo first-time founders, consultants, and small teams.
