Guillermo Rauch on Agent-Led Growth and the Software Factory
Guillermo Rauch, founder of Vercel and creator of Socket.IO and Next.js, spoke with a16z’s Gabriel Vasquez about the rise of AI agents and what he calls an “inexhaustible IQ machine.” Rauch described how companies can build a “software factory” that continuously learns and ships improvements, how Vercel consolidated internal automation into a single company-wide agent called V, and how agents already drive product discovery and purchases (what he terms “agent-led growth”). He emphasized that defensibility will come from the systems and verification loops built around models rather than from the models themselves.
Discusses the operational and commercial impact of AI agents and agent-led product discovery which can influence product monetization and automation strategies across tech companies and platforms.

Vercel CEO: Separate Models from Agents, Push Open Protocols
Vercel CEO Guillermo Rauch discussed the company’s role in evolving AI agents and the need to separate models from agents to preserve modular software engineering. Vercel reports about 6 million daily deployments (roughly half from coding agents) and more than 1 trillion tokens flowing through its AI gateway each day. Rauch described internal tools — a natural-language instructions framework called Eve and a Vercel Sandbox for applying data and policy controls — designed to make agents safe and auditable in production. He said customers are moving from single-lab lock‑in toward plug-and-play stacks (model, harness, data platform, sandbox, gateway) using providers like OpenAI, Anthropic and a range of open models. Rauch warned platform advances from major labs can compete with infrastructure providers and reiterated Vercel’s aim to enable open protocols and act as foundational infrastructure for agent-driven applications.
Guillermo Rauch's Key Insights for AI Startup Success
Guillermo Rauch, founder and CEO of Vercel and creator of Next.js, discussed product and team lessons for founders building in the AI era during a fireside chat with a16z partner Gabriel Vasquez. Rauch framed open source as a filter and “speedrun” to product–market fit: if free and easy-to-consume code does not gain users, the idea may be wrong. He emphasized ruthless focus—finding the single layer where a startup can be truly excellent—arguing that trying to build everything dilutes value. In an era where AI makes many implementations easy, Rauch counseled discerning which problems deserve investment, hiring rising talent who ship and communicate clearly, and retaining hands-on conviction by personally using and evaluating tools. He recommended broad experimentation followed by a strict bar for what is taken to market.
Vercel's Andrew Qu: Agents as a New Software Class
Andrew Qu, Chief of Software at Vercel, explains in an interview why AI agents represent a new form of software, how Vercel built internal agents and turned the lessons into the eve agent framework, and why Vercel is making its platform agent-friendly. Qu describes technical primitives (skills, filesystem agents, resumability, sandboxes, subagents), use cases for business automation inside Vercel (contract redlining, marketing retrospectives, query writing), and the idea of serving machine-readable content (Markdown) to agents. He also highlights ongoing challenges—secure code execution, long-running jobs, and collaborative or "multiplayer" agent development—and says Vercel intends to integrate observability and partner integrations while keeping developer onboarding simple.
