Customer Discovery Prover: Stop Guessing Your Product-Market Fit
This Connector changes that by turning your AI into a skeptical YC partner. Instead of letting the agent agree with your every assumption, it forces the agent to look for specific evidence. It demands named interviews, quoted pains, and actual commitment signals. You stop guessing and start building on a foundation of proven facts.

Where the request belongs
Work Customer Discovery Prover can move forward.
This is for the founder who is tired of guessing what the market wants and the product manager who needs to defend a roadmap with hard evidence rather than feelings.
Startup Founder
Validates ICP and WTP before spending a dime on engineering.
Product Manager
Ensures new features solve documented pains for specific, non-conflated segments.
VC Analyst
Audits a startup's customer discovery to see if they actually have a proven market.

Each Connector adds new actions and data without changing how you work.
Browse ConnectorsYC Startup Prover
Most startups die building solutions nobody asked for. A founder pitched for 20 minutes about their proprietary algorithm. never mentioned a single user, a single pain point, a single dollar of willingness to pay. That pitch would be rejected in 30 seconds at Y Combinator. This capability forces five PG-level axes: problem discovery, unscalable beginnings, metric discipline, user obsession, and core value focus.
Product Discovery Prover
Block engineering waste. This gatekeeper demands hard data, behavioral segments, and proven willingness-to-pay before a single line of code is written.
Techstars Mentor Prover
A founder pitched for 45 minutes without mentioning a single customer conversation, a single mentor challenge, or a single dollar of revenue. Zero feedback sought. Zero market validation. Zero network. That is not acceleration. that is solo building in a vacuum. This capability forces five Techstars-level axes: mentor leverage, feedback discipline, customer discovery, revenue readiness, and network strategy.
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.
Founder Vision Prover
A pitch deck said '1% of a $10B market' and 'run Facebook ads.' That is not a startup. that is a PowerPoint. This capability forces it to prove behavioral pain, calculate bottom-up TAM, show cohort retention, build a $0 CAC moat, and model unit economics that recycle capital in under 12 months.

Before you connect
Questions about Customer Discovery Prover.
The practical details behind the request, access and result.
How does Customer Discovery Prover stop me from making bad assumptions?
It forces your AI client to cite specific evidence from your interviews. If the agent can't provide a quote or a specific role, the capability flags the discovery as 'Assumed' or 'Invented.'
What is 'The Mom Test' and how does this Connector use it?
The Mom Test is a methodology for getting honest feedback by asking about past behavior instead of future promises. This Connector ensures your AI doesn't ask leading questions like 'Would you pay for this?'
Can I use Customer Discovery Prover to validate my ICP?
Yes. It specifically checks if your Ideal Customer Profile is grounded in real data or if it's just a list of demographics like age and interests.
Will this capability help me get more funding?
It helps you prepare for funding by ensuring your discovery survives investor scrutiny. It moves you from 'we think people want this' to 'we have evidence that this specific segment will pay.'
Does this Connector work for both B2B and B2C startups?
It works for any business model. It's particularly effective for B2B because it helps separate complex buyer segments that often get conflated as 'enterprise' or 'SMB.'
What happens if my discovery is rejected by the capability?
The capability provides a verdict matrix. It tells you exactly which pivot failed, whether it was biased validation, conflated segments, or lack of commitment signals, so you know exactly what to fix.
Does it conduct interviews?
No. It validates that your discovery process is grounded in real data. interview evidence, unbiased methodology, separated segments, and commitment-based WTP signals. It does not replace conversations with customers. It forces you to prove you had them.
What is The Mom Test?
A framework by Rob Fitzpatrick for conducting customer interviews that produce truthful data. The core rule: never ask leading questions about the future ('Would you use this?'). Instead, ask about past behavior ('When did you last encounter X? What did you do?'). People lie about future behavior. past behavior is a reliable signal.
Can pre-product startups use this?
Yes. it is designed for pre-product discovery. WTP signals for pre-product include: signed LOIs, paid design partnerships, deposits against future delivery, time commitments (agreed to a weekly feedback session), and reputation commitments (willing to be named as a design partner). You do not need a product to test willingness-to-pay.
