START Warsaw x Poland Tech Week Hackathon

This October, we’re bringing the START Warsaw hackathon back as part of Poland Tech Week 2026. Builders, founders, designers and engineers will work on challenges from companies with real problems to solve. The goal is simple: build a working prototype and show what it can do. Come with a team of 3–4 or apply solo and meet your teammates here. You’ll spend most of the time building, testing and preparing a demo. Bring a laptop, a charger, and something you want to prove. Our first two case partners are Reactive AI and Bending Spoons. Reactive AI is rethinking how AI models work, building a new architecture with memory at its core so AI can learn from interactions instead of starting fresh every time. Their track challenges teams to push the boundaries of AI benchmarking and rethink how we measure what AI can actually do. Bending Spoons , the technology company behind products such as WeTransfer and Evernote, has just opened an office in Warsaw. They’re joining with a challenge of their own for teams to tackle. The full briefs for both partners will follow. Like last time, OpenAI will be joining us as a technology partner, more details coming soon. ElevenLabs joins as a tool…
