​Build with voice. Move fast. Push what’s possible.

​Over one weekend in London, we’re bringing together exceptional builders to explore the future of human–AI interaction — powered by ElevenLabs’ world-leading voice technology.

​Hosted by Antler, the global VC backing founders from day zero, and in partnership with ElevenLabs, this hackathon is for those ready to go all-in: from blank page to working prototype in 48 hours.

​👤 Who we’re looking for

​We’re backing individuals with the talent and drive to go further, faster:

• ​Engineers, product thinkers, designers, creatives — all builders welcome

• ​Aspiring founders exploring voice, audio, and applied AI

• ​High-agency operators ready to collaborate, experiment, and move fast

​No team? No idea yet? No problem. We’ll form teams on Day 1.

​Apply by midnight Thursday 4 September. Places are limited and highly selective — we’re curating a group of exceptional, committed builders.

​What you’ll get

• ​Access to ElevenLabs’ powerful voice APIs, credits, and tools

• ​Mentorship from the ElevenLabs and Antler teams, plus more partner experts to be announced

• ​Workspace, fuel, and pizza + drinks hosted by Antler each evening

• ​A chance to demo to top operators, investors, and product minds in AI

​Prizes

• ​£1,000 cash prize for the most innovative build

• ​ElevenLabs credits for the most unhinged creation

• ​Bragging rights for the project most likely to hit #1 on Product Hunt

  • ​Winning teams are fast-tracked into interviews for Antler’s Autumn 2025 residency, kicking off 7 October — the place for founders to go further, faster.
