Startup Sprint: Prove you're fundable

Build It. Test It. Prove It.

Smells like a hackathon. Runs like a pressure test, on you, not just your idea.

Proving Ground runs a three-day Sprint where judges push past the pitch. No script survives real questions about what you tried, what broke, and what you changed.

Past teams have gone on to raise from 500 Global and Blitzscaling Ventures, and been accepted into Berkeley SkyDeck and Confluent's accelerator, independently, without Proving Ground's involvement in those decisions.

What this is

A hackathon judges what you built by the end. We watch during the process and look past the end to what may come next.

The team is almost everything. How you make decisions under pressure, how you handle a setback, how you treat each other when something breaks. You'll document that as you go. What we ask you to show and how we question it are built around behavior, not performance.

How it works

Over three days, founders build under real constraint. No script, no rehearsed demo. Judges probe what you tried, what broke, and what you changed, and compare where you started to where you ended.

Two Tracks

Discovery Track. Pre-market, no active customer contact yet. For the startup curious, including enterprise folks seriously exploring a leap.

Pre-seed Track. In-market, already talking to customers. Ship something real, show what's changed, pressure-test your next move.

After the Sprint

Select teams get invited into the Street Test: 30 days back in the real world, no artificial deadline, no audience. This is where we see if momentum was real or borrowed from the room. It's the part a hackathon can't offer, because a hackathon ends when the weekend does.
