SaaS Destroyer Hackathon

Companies pay thousands a year for software that’s really just a dashboard, a form and a database. We believe a small, cracked team with AI can rebuild it in a day.

Join us in Cambridge, MA for a one-day hackathon to prove it. Pick any paid software product with public pricing, rebuild the part that matters in eight hours, and work out what it costs to run.

No decks. No term sheets. You keep everything you build.

Saturday, November 14, 2026 9 AM – 8 PM · Harvard St. Commons, Cambridge MA · Free · Solo or teams up to 4

How it works

  1. Pick your target. Any paid software product with pricing you can look up.
  2. Start from an empty repo. Open source, models and coding agents are all fine. Code you wrote before today isn't.
  3. Show your numbers. Their yearly price, your yearly cost, and the gap between them.

Scoring

score = 50% money saved + 50% product quality

FAQ

Who can enter?

Anyone who builds — students, dropouts, engineers, designers, people with day jobs. Entry is free. Come alone and we will help you find a team at 9 AM.

Do I keep what I build?

All of it. No equity, no fees, no claim on your work. We are not an investor and this is not a demo day.

Can I prepare beforehand?

Research your target as much as you like. Code starts at 10 AM in an empty repo and stops at 6 PM, and we look at commit history.

What do I bring?

A laptop, a charger and your own accounts. Food, coffee and sponsor credits are covered.

Can we sponsor it?

Yes. We are looking for model and compute credits, prize money and food. Write to team@saasdestroyer.com.
