Vercel's COO Jeanne DeWitt Grosser took a 10-person SDR team down to 1. The whole thing costs $5,000 a year. In her session at SaaStr AI 2026, Jeanne breaks down exactly how Vercel automated core go-to-market functions with AI agents in production. Not a demo. The real version, with the costs, the build process, and the mistakes included. What you'll learn: How the lead qualification agent replaced 10 people for under $5K/year (a 32x ROI) The support agent now handling 93% of total case load, and the content agent doing 96% of major content updates The "tripod" build model: GTM engineer + data scientist + best subject-matter expert How they shadowed their best SDR, encoded every tab she opened, and shipped an agent that performs like a 90th-percentile rep 100% of the time The three things that matter: headless composable architecture, a real data foundation, and the flipped build-vs-buy calculus Vertex, their in-house support agent: $150K/year and 3 engineers vs competitors running 150 engineers Why most teams hit cost and infrastructure walls at scale, and the mistakes to avoid CHAPTERS 0:00 Standing up GTM engineering in June 2025 1:05 93% of support, 96% of content, automated 1:33 The lead agent: 10 people to 1 2:25 The tripod build model 3:11 2025 was assistance. 2026 is agents. 4:19 Why old cloud infrastructure breaks at scale 6:35 The three things that actually matter 8:00 Deal One: the meeting intelligence agent 9:16 The Playbook Platform 11:11 D0 and the data foundation 12:54 The build-vs-buy calculus has flipped 14:12 How they built the lead agent 15:32 Vertex and the real cost breakdown 16:39 Running it all on Fluid compute 17:44 Why GTM is turning into consulting 18:47 The recap: three takeaways SaaStr AI is coming back.
