PlebTest

PlebTest gives your market a voice—without you having to pick up the phone.

The Problem: Founders skip customer validation because talking to strangers is painful. They build blind, discover too late nobody wants it, and waste months on the wrong idea. 42% of startups fail from no market need.

How PlebTest Solves This:

1. Describe your idea (problem, solution, hypotheses)
2. Define your ideal customer profile (ICP)
3. AI generates diverse personas based on your ICP
4. Personas challenge your assumptions through simulated conversations
5. Get a clear verdict: Kill, Pivot, or Build

What Makes It Work:

• Anti-sycophancy by design: AI is built to challenge, not flatter
• Collective intelligence: Multiple personas find holes no single conversation could
• Pivot intelligence: Doesn't just kill bad ideas—shows you how to twist them into winners
• Speed: Get honest market feedback in minutes, not months

Who It's For:

• Technical solo founders who would rather code than cold-call
• Side-hustle builders with full-time jobs who can't schedule calls
• Domain experts starting their first business with crippling imposter syndrome

Founders skip customer validation because talking to strangers is painful. They build blind, discover too late nobody wants it, and waste months on the wrong idea. 42% of startups fail from no market need. Founders avoid cold calls due to phone anxiety, introversion, or time constraints. ChatGPT and other AI tools give sycophantic feedback that confirms bad ideas. The cost: 3-6 months wasted building the wrong thing, runway burned on features nobody wants, and winning ideas sit unbuilt while chasing losers.

PlebTest gives your market a voice without you having to pick up the phone. Users describe their idea (problem, solution, hypotheses), define their ideal customer profile (ICP), and AI generates diverse personas based on that ICP—varying demographics, psychographics, and personality traits. These personas challenge assumptions through simulated conversations and deliver a clear verdict: Kill, Pivot, or Build. The anti-sycophancy engine is built to challenge, not flatter. Collective intelligence from multiple personas finds holes no single conversation could. Pivot intelligence doesn't just kill bad ideas—it shows how to twist them into winners.
