Sam Coope was the first engineer to join us at Jack & Jill.
He built the world’s first fully neural voice agent at PolyAI in 2018. He has eleven papers and five patents in conversational AI. Remarkable.
This weekend, he’s co-hosting our hackathon with Brickwise.
It begins with a rooftop reception on Friday 24th evening. The perfect chance to network, swap ideas, and find a cofounder if you’re applying solo.
The hackathon then runs the full following day in central London - fuelled by unlimited food and drinks. Sam will deliver a live Q&A on building production AI agents.
This is an opportunity to build for one weekend, and walk away as a founder.
First place earns a guaranteed YC interview with Tom Blomfield and a partner meeting with Capital T.
