YC Readiness

Promising, but the evidence is uneven.

The foundation is credible, but several claims still need stronger user or traction evidence.

Evidence Gap

You show early user interest, but there is not yet enough evidence of repeat usage or retention. Expect YC to probe whether users actually come back.

Not a generic checklist. Your report changes based on your stage, traction and actual answers.

What YC Is Really Testing

The questions look simple. The signals underneath them aren't.

Your application is revealing more than the answers themselves. These are six signals a reviewer is trying to understand about the company and the founders behind it.

What We Actually Review

We don't just edit answers. We pressure-test the whole application.

Every answer has to work on its own, but the application also has to hold together as one clear, credible startup story. We review both.

01
Founders
Background, founder-market fit, motivation, credibility, and ability to execute.
02
Problem & Customer
Importance, urgency, customer understanding, insight, and existing alternatives.
03
Product & Progress
Product clarity, real usage, traction, learning, progress, and speed of execution.
04
Business & Market
Business model, market opportunity, competition, differentiation, and growth potential.
05
Narrative & Credibility
Clarity, evidence, consistency, ambition, numerical accuracy, and the complete story.

We do not review each answer in isolation. We examine whether the complete application presents one clear, credible, and convincing startup story.

What You Receive 8 Practical Outputs
The most important issues are ranked so you know what to fix first and what can wait.
Specific guidance shows what each important answer needs to communicate more clearly.

Before You Start

Questions founders ask.

No. FounderHQ is an independent service and is not affiliated with, endorsed by, or connected to Y Combinator in any way. This tool is built from patterns in what YC partners have publicly said they screen for, applied to your specific startup.
Yes. No card required, no hidden cost. The score, category breakdown, and full question-by-question report are all free.
The Fundability Assessment scores your business broadly across the five pillars investors evaluate: Opportunity, Economics, Growth, Narrative, and Evidence. This tool is narrower and sharper, built specifically around what YC partners screen for: team, traction, idea quality, market ambition, and execution speed. If you're applying to YC while also raising more broadly, doing both gives you the fullest picture.
It's a self-reported diagnostic, not a prediction of acceptance and not a guarantee. It's built to reflect the categories that actually move the needle in a YC application and interview, not a generic startup quiz.
Nothing you don't choose. Your full report is already on the page and in your inbox. If you want help closing the gaps before you apply, that's what the Fundability Audit is for, but there's no obligation.
You'll get your report by email right away. We may follow up occasionally after that. Never a hard sell, and always easy to opt out.
Ready When You Are

Don't apply blind.

Know exactly which of the five areas will hold your application back before a partner reads it. Two ways to close the gap.
