AboutHappyRobot

HappyRobot is the AI-native operating system for the real economy—a system that closes the circuit between intelligence and action. By combining real-time truth, specialized AI workers, and an orchestrating intelligence, we help enterprises run complex, mission‑critical operations with true autonomy.

Our AI OS compounds knowledge, optimizes at every level, and evolves over time. We’re starting with supply chain and industrial‑scale operations, where resilience, speed, and continuous improvement matter most—freeing humans to focus on strategy, creativity, and other high‑value tasks.

HappyRobot has raised $62M to date, including our most recent $44M Series B in September 2025. Our investors include Y Combinator (YC), Andreessen Horowitz (a16z), and Base10—partners who believe in our mission to redefine how enterprises operate. We’re channeling this investment into building a world‑class team : people with relentless drive, sharp problem‑solving skills, and the passion to push limits in a fast‑paced, high‑intensity environment.
