{Tech: Europe} x Cala Hackathon | The Summer Lock-In

A 60-person, single-day AI hackathon for people who would rather ship than switch off in late August. Co-hosted by {Tech: Europe} and Cala, the day opens with participant matchmaking so you can find teammates before building starts, runs twelve hours with mentor support, and closes with live demos and an award ceremony at 20:45. Entering the competition is optional — opt in by 19:00. Every technology partner provides free credits, with OpenAI, Pioneer by Fastino Labs, Fal, Entire, Latitude and Aikido confirmed, covering multimodal models, generative media, agent reliability and security tooling. Lunch and dinner are included. Attendance is by approval and the venue is shared once you are accepted.
