Adversarial AI · Built to break your idea

The AI Co-Founder
That Tries to Kill Your Startup
Before the Market Does.

Most startups die quietly, eighteen months and $400k in. Ours die loudly, in private, on day one. An adversarial AI that argues against your idea with the full weight of the market — so you only build what survives.

Attacking
Fatal
Nobody actually has this problem.
Your TAM is built on a survey of 12 friends. Real buyers don't search for this. There is no budget line item.
Critical
Your moat is a feature, not a company.
Notion ships this in a weekend. Your six-month roadmap is their Q3 changelog.
High
Unit economics collapse at scale.
CAC at $340, LTV at $190. You're paying customers to leave you. No amount of growth fixes this.
Survival probability after fixes

The Devil's Advocate

Yes-men build dead startups.
The Devil keeps you alive.

Every other tool is built to make you feel good. The Devil is built to make you right. It pulls comp data, scans category dynamics, runs your numbers, and builds the strongest possible case that your startup is doomed.

Then — only then — it tells you what to change so it isn't.

Attack

"You're describing a feature Notion will ship for free in twelve months. Distribution moat? Zero. Switching cost? Zero. Why does this exist?"

Counter

Narrow to a vertical where Notion is too horizontal — legal ops at 50-500 person firms. Build the workflow, not the doc. Defensibility becomes integrations + compliance, not UI.

Co-founder OS

One question, answered with evidence.
