CTO Voices x "Hello, AI speaking" (Hexa)

A tight technical evening on voice AI at Hexa, the startup studio behind eFounders. The premise: 200ms of latency is what separates a voice agent that passes for human from a bot people hang up on — and in two years voice has gone from Twitter demos to production SDRs and support agents. On stage are Pierre-Baptiste Béchu, co-founder of Aircall ($226M raised, unicorn, hundreds of millions of calls/day), and Olivier Teboul, co-founder & CTO of Gradium (Kyutai's next-gen voice model), in conversation with Hexa CTO Tanguy Goretti. Worth it for technical founders building with AI who want real numbers from operators who shipped, not a panel of talking heads.
