Premortem
Premortem is an AI red-teaming tool that evaluates startup ideas across market, tech, competition, and unit economics.
Premortem is an AI red-teaming platform designed to stress-test startup ideas. Users paste a startup idea to initiate analysis from multiple perspectives. Six specialized AI agents simultaneously analyze and critique the idea across domains like market viability, technology, competition, and unit economics. A seventh synthesizer agent compiles these critiques into a structured written memo. The process delivers the completed memo in under 90 seconds, helping founders find flaws before committing resources.
