Pitch Deck Prover
An AI built a pitch deck that claimed a '$4.2B TAM' with no source, described the problem as 'everyone struggles with this,' showed '15K downloads' as traction with 3% D30 retention, and asked for 'funding to accelerate growth'. no amount, no use of funds, no milestones. The deck got rejected in 8 minutes. This capability forces problem validation with evidence, sourced market sizing, defined unit economics, retention-based traction, and a specific fundraising ask.

Before you connect
Questions about Product Discovery Prover.
The practical details behind the request, access and result.
How does Product Discovery Prover help my team avoid building the wrong features?
It acts as a hard gate that requires you to provide evidence of problem scale and purchase intent before engineering can start. This prevents you from spending months building features that nobody actually wants.
Can Product Discovery Prover help me define my target audience?
Yes. It forces you to move past vague demographics like 'small businesses' and define users by their specific behaviors, current capabilities, and workflow friction.
What is the difference between interest and purchase intent in Product Discovery Prover?
Interest is a compliment like 'that sounds cool.' Purchase intent is concrete data like pre-orders, letters of intent, or people already spending money on a workaround.
How does Product Discovery Prover help with MVP scoping?
It forces you to define the minimum experiment needed to test a core hypothesis. If your MVP takes more than 4 weeks to build, the Connector will flag it as bloated.
Can I use Product Discovery Prover to analyze my competitors?
Yes. It requires you to actually test competitor products for real tasks and document their strengths, gaps, and the switching costs for your potential customers.
What happens if Product Discovery Prover rejects my product idea?
It identifies a specific blind spot in your thinking, such as a lack of evidence, a vague segment, or a lack of purchase intent. You can then fix that specific issue before you start building.
Why does the capability reject demographic segments?
Because demographics are useless for product design. 'Millennials' is a marketing category, not a workflow. We demand behavioral segments because they isolate users actively experiencing the exact pain point you intend to solve.
What qualifies as valid purchase intent?
Money or legally binding ink. Polite compliments and 'I would use this' are false signals that kill startups. We require active commitment: credit cards on file, signed B2B Letters of Intent (LOIs), or cash deposits.
How should an MVP be scoped?
As a single-variable experiment. Drop the settings panels, user profiles, and polished UI. The MVP must isolate and test the core value hypothesis. Use manual back-end workarounds to deliver the outcome without building the platform.
