Gravitee, a leading Agentic API and Event Management company, announced it has raised $60 million in Series C funding. The funding round was led by Sixth Street Growth, the growth investing business of Sixth Street, with participation from existing investors Riverside Acceleration Capital and AlbionVC.
Since its founding, Gravitee has raised over $125 million in funding, driving its mission to shape the future of APIs, Event Streams, and Agentic AI.
The big-picture problem Gravitee is addressing is the growing complexity and fragmentation of modern digital systems. And APIs, event streams, and now AI agents all power mission-critical workflows. However, they each come with their own tools, protocols and security challenges. The historically siloed approach creates blind spots, increases risk and slows down innovation. Gravitee unifies security and governance across APIs, real-time events, and AI agents in a single platform, helping companies future-proof their architecture, regain control and hold nothing back as they scale.
Legacy API management vendors provide traditional approaches that were not designed for real-time and multi-cloud or agentic environments. And they fail to provide unified control or deep governance across event-driven and traditional systems, leaving gaps that compromise scalability and security.
Gravitee’s Agentic API and Event Management platform, however, combines traditional API gateway functionality with event-native and AI-integrated governance capabilities. And it was designed to orchestrate, secure and observe all traffic – synchronous or asynchronous – across legacy and emerging digital environments.
Gravitee was launched in 2015 and serves hundreds of global brands, including BlueYonder, Michelin, Roche, Tide, Verint and Xylem.
New board member: Michael Bauer has joined Gravitee’s Board of Directors as part of the transaction.
KEY QUOTES:
“Modern companies are integrating AI agents, streaming data, APIs and hybrid systems faster than ever, but legacy tools can’t keep up. As a result, many companies face major risks around security, observability and control of their API and event infrastructure, which isn’t built for this new, dynamic world. Gravitee has established itself as the leader in Agentic API and Event Management. The new funding will allow us to accelerate further, enhance our products and expand into new markets.”
Rory Blundell, CEO of Gravitee
“We are excited to support Gravitee’s mission to help companies innovate and grow with unified, secure API management.”
Bo Stanley, Partner at Sixth Street and Co-Head of Sixth Street Growth
“Gravitee is redefining the standard for modern API management platforms, integrating governance and controls for event streaming and AI agents. Gravitee is well positioned to meet the complex demands of tomorrow’s digital infrastructure with its unique combination of end-to-end functionality, ease of use and pace of innovation.”
