SummerUP – Launch your startup from 0 to 1 | One Week of Building & Selling
Sell before you build – Turn your idea into a working MVP with your first paying Customers in just one week!
Go from raw idea to a working MVP with real paying customers in a single week, then pitch it live to hundreds of founders & investors on The Delta Stage.
SummerUP flips the script on every hackathon you've done. It's built for people who can actually ship - developers, designers, and operators who'd rather validate fast and close their first customers than polish another idea-stage deck.
Come solo or bring your crew. We bring the mentors, the campus, and the playbook; you bring the ambition to walk away with traction, not just another prototype.

Recap from last year:
🥇 Havoc, our 2025 1st place team, built outbound sales agents using natural language and generated a €127.8k ARR pipeline in 7 days — including 8+ LOIs from companies like Figma, Gartner, Enpal, AWS, Shopify, and more.
🥈 Fertara, our 2025 2nd place team, validated a fertility support platform with 3 couples signed up for a €500 p.p. paid beta, 34 sign-ups, and 2 coaches onboarded — in one week.
🚚 LogBot, which closed its first paying customers & built its MVP at SummerUP, secured six-figure funding through SummerUP — and now offers AI dispatching, phone assistants, email automation, and its own AI-first TMS for the logistics sector.
This is what one week of selling before building looks like. This year, we're going bigger.
