Marcus Reyes

Marcus Reyes is VP of Operations at Clearbit, where he oversees the systems, tooling, and workflows that keep a fast-growing data company running. He has spent the last 18 months leading Clearbit's internal AI agent program — a ground-up effort to identify which operational workflows could be handed to AI agents and which ones required humans to stay in the loop.

The results have been measurable: a 40% reduction in manual ops workload across three core teams, achieved not through a single sweeping implementation but through a series of targeted agent deployments, each one tested against failure before the next one began. Two of the agents they built are now being productized for Clearbit's own customers.

At BuildWithAI Summit, Marcus presents a ground-level case study of the entire process — the identification framework, the deployment sequence, the two agents that failed before the three that stuck, and the metrics his team uses to decide when an agent is actually ready to run without supervision.
