General Partner at Y Combinator focused on AI and technical founders. He previously co-founded Reverie Labs, a machine-learning drug discovery company acquired by Ginkgo Bioworks in 2024, and was a deep learning researcher with a BA/MS in Computer Science from Harvard.
World Models Aim to Replace Robotic Trial and Error
Ankit Gupta and François Chaubard argue that AI needs world models—systems that predict how an environment will change after an action—to escape the poor sample efficiency of trial-and-error learning. They contend that passive video could provide broad knowledge of physical change, then be paired with smaller action-labeled datasets to train robots in simulated rollouts. But Chaubard says the approach still faces hard limits in large action spaces, rare safety-critical events, real-time planning, and adaptation when physical conditions differ from the model’s predictions.
Giga Says Product Velocity Beat a 400-Person Rival at DoorDash
Giga co-founder Varun Vummadi argues that enterprise AI companies win less by selling a vision than by proving, in paid deployments, that their product can move a customer’s operating metrics. In a Startup School India interview with YC general partner Ankit Gupta, Vummadi traces how Giga abandoned its original edtech idea, followed customer demand into support automation, and used a small engineering team to win accounts including DoorDash. His broader case is that AI startups should charge early, iterate against real business KPIs, and treat product performance as their strongest sales tool.
