Gravitee tackles the fragmentation of digital systems where APIs, event streams, and AI agents operate with disparate tools and protocols. This siloed approach creates security risks and slows innovation. Gravitee’s platform unifies security and governance, enabling seamless orchestration of synchronous and asynchronous traffic across legacy and modern environments. “Modern companies are integrating AI agents, streaming data, APIs, and hybrid systems faster than ever, but legacy tools can’t keep up,” said CEO Rory Blundell.
Unlike legacy API management vendors, Gravitee’s platform is designed for real-time, multi-cloud, and agentic environments. It combines traditional API gateway functionality with event-native and AI-integrated governance, addressing scalability and security gaps. Posts on X highlight its ability to manage both synchronous and asynchronous APIs, a key differentiator noted by @saas_penguin. The platform’s open-source roots and enterprise-grade features have driven adoption by hundreds of global brands, with annual recurring revenue reaching $22 million in 2024.
The $60M funding will accelerate product development and market expansion, with plans to grow Gravitee’s team from 130 to 200 employees by year-end. Michael Bauer, Managing Director at Sixth Street Growth, joins the Board of Directors, praising Gravitee’s “end-to-end functionality, ease of use, and pace of innovation.” Bo Stanley, Partner at Sixth Street, emphasized support for Gravitee’s mission to drive secure API management. The involvement of existing investors Riverside Acceleration Capital and AlbionVC underscores confidence in Gravitee’s vision.

Its platform supports mission-critical workflows for clients like BlueYonder and Roche, enabling innovation without compromising security. “Gravitee is redefining the standard for modern API management platforms,” said Bauer, highlighting its role in future-proofing digital infrastructure. The funding announcement sparked positive sentiment on X, with @AlbionVC noting Gravitee’s leadership in Agentic AI and API management.
