In December 2025 I competed in the ElevenLabs × Project Europe hackathon in Warsaw, a unique 20‑hour event combining AI innovation with a creative build sprint. The hackathon brought together roughly 130 builders from across Europe, hosted in a converted historic building for one intense product‑building weekend. :contentReference[oaicite:1]{index=1}
🛠 What the Hackathon Was About
Participants were selected as part of a continental challenge — roughly 30 top teams were flown in to build solutions using ElevenLabs voice‑AI tech and APIs in ~20 hours. :contentReference[oaicite:2]{index=2}
The vibe was more like a tech festival than a typical hackathon, with food trucks, wellness zones, and pro‑builder support everywhere. :contentReference[oaicite:3]{index=3}
🚀 Our Project
We focused on an AI‑enhanced voice‑powered assistant tailored for creative workflows:
- Uses ElevenLabs voice models for expressive output
- Real‑time audio data pipelines
- Integrated NLP idea exploration features
Getting this early AI work demoed under time pressure taught us a lot about practical teams vs theory.
🏆 Results & Reflection
Our team placed in the Top 10 among the participants (a massive achievement given the high‑level developer pool), and the event itself expanded my view of where voice AI and user experiences can go.
This event wasn’t just a hackathon — it was a community and learning ecosystem showing how AI innovation travels fast when builders connect. :contentReference[oaicite:4]{index=4}
