Gravitee, a platform that helps companies manage APIs, raises $60M

Gravitee, a platform designed to help companies manage their APIs and other digital traffic pipelines, has raised $60 million in a Series C funding round led by Sixth Street Growth with participation from Riverside Acceleration Capital and Albion VC.

The new capital, which brings Gravitee’s total raised to just over $125 million, will be used to fund the development of new product features and Gravitee’s expansion into new markets, said CEO Rory Blundell.

Modern data systems are complex. APIs, for example — the set of rules that allow different apps to communicate and exchange data — often come with their own tools and protocols. Blundell makes the case that companies risk creating blind spots and slowing down innovation without a control plane to tie disparate systems together.

“[C]ompanies are integrating AI agents, streaming data, APIs, and hybrid systems faster than ever,” Blundell said in a statement. “As a result, many companies face major risks around security, observability, and control of their API and event infrastructure.”

Blundell founded Gravitee in 2015 alongside developers Azize Elamrani, David Brassely, Nicolas Géraud, and Titouan Compiegne. What started as an open source project quickly evolved into a business. Today, Gravitee offers paid services to fund development of its freely available software.

The Gravitee platform can be deployed on-premises, self-hosted, or used as a part of Gravitee’s software-as-a-service plan. Features across all releases include a tool for designing APIs and deploying them ahead of mock testing as well as a dashboard from which users can visualize the components of their API deployments.

Gravitee competes with Blobr, which offers software for exposing and monetizing enterprise APIs. Another top rival is StepZen, a company developing graph tech to help connect and visualize various APIs.

Blundell claims that Gravitee is differentiated by its support for both asynchronous APIs (i.e. APIs that return data at a later time) and synchronous APIs (APIs that return data immediately). Some vendors don’t offer this.

Gravitee has hundreds of customers today, according to Blundell, including Blue Yonder, Michelin, Roche, and Tide. Annual recurring revenue reached $22 million in fiscal year 2024.

Gravitee employs around 130 customers and plans to end the year with roughly 200.
