The Al Lab Founder Who Sees The Future First | Karan Goel, Founder & CEO of Cartesia

Karan is the co-founder and CEO of Cartesia, an AI model lab building the next generation of real-time voice intelligence.In this episode, Karan explains what all goes into building an AI Lab company; from massive datasets to pre-training to post-training to inference engines, plus a heavy dose of relentless evaluation, and obsession with every layer of the stack. We also discuss why existing AI benchmarks are not very helpful, why latency is voice AI’s biggest enemy, and why maintaining context across long conversations is one of the hardest unsolved problems.Apart from the cutting edge tech, this conversation explores Karan’s journey from researcher to founder, building Cartesia with a five-person founding team, raising capital, and realizing why first-time founders waste years focusing on things that ultimately don’t matter.If you want a glimpse into the future of AI, watch this episode.00:00 Trailer01:35 From DPS to Stanford to Cartesia02:35 From Counter-Strike to AI04:28 Another Research Paper Wasn’t Enough06:48 The Story Behind “Cartesia”07:17 Building a Company With Five Technical Founders09:55 From Research Project to Startup13:54 Cartesia’s Audacious Vision for 203515:07 What It Takes to Build an AI Model Company18:55 Why Faster AI Doesn’t Have to Be Worse24:12 AI Still Has a Memory Problem27:14 Why Context Builds Trust27:50 Will AI Replace Entire Account Teams?29:16 Hold Music Is Now a Salesman30:30 Designing AI That Feels Personal31:31 Building With Cartesia34:48 Voice AI’s Enemy #1: Latency38:50 Why AI Labs See the Future First41:32 Finding Product Market Fit45:34 Great Products Don’t Need Much Marketing48:12 Very Few Things Matter52:26 How Big Can Voice AI Get55:53 Fundraising And Mission58:15 What Cartesia Is Ultimately Building-------------India’s talent has built the world’s tech—now it’s time to lead it.This mission goes beyond startups.
