What founders say
"It told me three things I didn't want to hear. All three turned out to be true. Saved me six months."

Marcus R.
First-time founder, Sydney
"My co-founder and I disagreed on the idea. FoundersChecker settled it. The pivot recommendation was spot on."
JL
Jess L.
Serial entrepreneur, London
"Every accelerator mentor sugarcoated it. This didn't. That's exactly what I needed before pitching investors."
DK
Dev K.
Pre-seed founder, Toronto
"I've run five ideas through it. Two got Proceed, two got Pivot, one got Kill it. All five assessments were fair."

Pro users save ideas, track versions, and compare iterations over time. Your ideas stay in a private vault — only you can see them.

Sample report
AI-powered invoice chasing app for freelancers
Verdict: PIVOT
💡 The idea in plain English
A SaaS tool that automatically sends payment reminder emails to clients when invoices go past due, on behalf of freelancers.
📊 Market reality
The market is real but already well-served. FreshBooks, HoneyBook, Bonsai, and Wave all include automated payment reminders as a core feature. You would be competing with bundled functionality inside products freelancers already pay for.
⚠️ Three most likely reasons this fails
1
Freelancers won't pay a separate subscription for one feature already included in their invoicing software.
2
Email deliverability issues make automated chasing unreliable — clients start ignoring the reminders.
3
No clear distribution channel. Acquiring freelancers one by one is expensive at a $15/month price point.

Common questions
Is the feedback actually honest or just negative?
It's calibrated, not contrarian. If an idea has real merit, the analysis will say so. The goal is accuracy — not pessimism for its own sake.
What happens to my idea on the free tier?
Free analyses are stored and may be used anonymously to improve the product. We don't act on individual ideas. Upgrade to Pro for complete privacy.
If Pro stores my ideas, how is that private?
We store your ideas so you can access your history — but only you can see them. We don't read them, share them, or use them to train our models. Think of it like a private notebook we hold but can't open.
Can I cancel anytime?
Yes. One click in your account settings, no questions asked, no email required.
