As agents increasingly take action in real-world contexts, durable execution is higher stakes than ever. That’s why a16z is thrilled to lead @temporalio’s Series D. Temporal is the code execution layer for critical workflows. Leading AI labs and AI-native companies, like OpenAI, Replit, Lovable, and Abridge, all rely on Temporal. Temporal abstracts away that complexity by handling retries, state management, orchestration, recovery, and replay automatically, allowing developers to focus on business logic instead of the difficult plumbing of huge distributed systems. For long-running agents operating over extended horizons, the durability that Temporal provides is the difference between a compelling demo and a production system. There are no two people better-suited to solve this problem than Temporal’s cofounders, Samar Abbas and Maxim Fateev, who have spent their careers at the frontier of distributed systems. We believe Temporal is defining that layer, and we’re thrilled to partner with Samar, Maxim, and the entire team as they build the execution backbone for software that acts.
