1. Technology overview
Gravitee is an open-source-rooted API management company founded in 2015 by developers, with headquarters in Denver, Colorado and offices in London and Lille. It addresses the problem of governing APIs, event streams and AI agents across many gateways and teams.
The platform combines an API gateway, observability, governance and a developer portal for REST, SOAP, GraphQL, gRPC, WebSocket and webhooks. It adds an event gateway for Kafka and similar brokers, an AI gateway for agents, and federated management of third-party gateways such as AWS, Apigee and MuleSoft. Named customers include Michelin, Swiss Post and Roche.
