Tenth Man

Most AI tools optimize for agreement. Tenth Man optimizes for dissent. Three agents - Strategist, Skeptic, Synthesizer - run structured adversarial analysis on your decision. The Skeptic attacks assumptions. The Synthesizer makes a call. Confidence is capped by what's unresolved, not by how good the answer sounds. No chat. No "it depends." A real decision brief. I built Tenth Man because I kept watching smart founders make bad decisions due to a lack of opposition. Every advisor in the room agreed. Every AI tool they consulted found a way to validate the plan. And there was no structural mechanism to force anyone to assume the crowd was wrong. The Tenth Man doctrine comes from military intelligence: if nine people agree, the tenth must disagree. The assumption is that consensus, by itself, is a blind spot. So I built a three-agent, three-model system where dissent is mandatory.
