AgileRL raises £5.5m in seed funding led by Fusion Fund to expand operations.
Fusion Fund led the seed round, which will fund a new San Francisco office and team expansion.
AgileRL provides an open-source platform and managed RLOps tools to accelerate reinforcement learning for artificial intelligence models. The company is based in London and San Francisco.
AgileRL has secured £5.5m in seed funding to support its international expansion and recruitment drive. The round was led by Fusion Fund, with participation from Flying Fish, Octopus Ventures, Entrepreneur First, and Counterview Capital.
The startup provides tools that reduce the time and expense required to train reinforcement learning models. The new capital will be used to open an office in San Francisco and hire more than a dozen new staff across engineering and go-to-market roles.
From the founder
"Having built a reinforcement learning system from scratch at my last company, I saw firsthand how costly and complex it is. No company in 2026 should need a full AI research lab just to use RL. Our goal is to make reinforcement learning a standard tool in every company’s tech stack."
Param Kumar
co-founder at AgileRL
Investor perspective
"Reinforcement learning remains the gold standard of AI training, yet very few companies actually have the resources to implement it in house. As hundreds of thousands of companies continue to invest in AI, AgileRL will undoubtedly play a key role in powering this revolution."
