The real risk
A bad idea doesn’t just cost money.
It takes the things you can’t earn back.
Your best years
Two years spent proving the wrong thing is two years your competitors keep.
Your relationships
Stress follows you home. So does the question nobody wants to ask: was this ever real?
Your reputation
Friends will encourage you. Yes-man AI will praise you. Neither pays the bill when the thesis breaks.
The difference
Most AI helps you sell the story. ThesisDue tests whether the story is true.

FAQ
Fair questions. Straight answers.
Is this just ChatGPT?+
No. ThesisDue is built around CAEM-B2B, a defined diagnostic method. The AI follows the method; it does not improvise generic startup advice.
What if my idea gets a PASS?+
Then you found out before the expensive part. You’ll see which evidence failed and what would need to change. Sometimes the right next step is to fix it. Sometimes it is to walk away.
Is my idea safe and confidential?+
Share only what you are comfortable entering online. We treat your diagnostic as private, but we do not make claims here about provider retention or model training that we cannot independently verify.
How long does it take?+
Set aside about 25–40 focused minutes. Rushing gives you a prettier lie. Honest answers give you a useful verdict.
