Gravitee, the leading open-source API and Event Management platform, has announced a $60 million Series C funding round, marking a major milestone in its journey from a bold developer-led vision to a category-defining technology leader.
The round was led by Sixth Street Growth, with participation from existing investors Riverside Acceleration Capital and AlbionVC.
This substantial round—secured amid a challenging investment climate—underscores strong confidence in Gravitee’s innovative approach to API management. The funding will fuel continued expansion and product innovation, especially in its flagship Agentic API and Event Management Platform (AAEM), designed to support secure, observable, and orchestrated agentic systems, APIs, and event streams.

“While others have scaled back, Gravitee has surged forward—outperforming peers, winning enterprise trust, and cementing our place as the most forward-thinking API Management platform on the market,” said Rory Blundell, CEO of Gravitee.
Gravitee has been at the forefront of innovation by pioneering Event-Native API Management, embracing a hybrid future of REST and streaming APIs, and embedding governance and security at the heart of its platform. As the demand grows for more resilient and intelligent infrastructure—particularly in the era of AI—Gravitee aims to extend its robust governance and observability capabilities into AI agent management as well.
Founded by four open-source-focused developers, Gravitee has grown into a trusted partner for enterprises seeking to future-proof their digital ecosystems. Its open-source roots, commitment to transparency, and relentless customer-first approach continue to set it apart in a space traditionally dominated by legacy players.
