About
Gravitee is an open-source API management and governance platform founded in 2015 in Lille, France, built on the mission of giving engineering teams a flexible, open foundation for managing the full lifecycle of APIs, events, and AI agent interactions. The company's core technology is a developer-friendly API gateway and management platform available under an open-source license, enabling organizations to adopt and customize the platform without vendor lock-in — a critical differentiator in a market historically dominated by expensive proprietary solutions.\n\nGravitee's platform has expanded well beyond traditional REST API management to cover asynchronous APIs, Kafka governance, and emerging agentic AI oversight use cases. Its product suite includes an API gateway, developer portal, access management, and API analytics, all deployable on-premises or in the cloud. The company serves organizations ranging from fast-growing startups to large enterprises in financial services, telecommunications, and healthcare, where API sprawl and governance complexity are acute problems. Its open-source roots and active community give it distribution advantages in developer-led buying motions.\n\nGravitee raised a $60 million Series C in May 2025, bringing total funding to more than $125 million and validating investor confidence in its expanded platform vision. As organizations adopt AI agents that communicate through APIs and events, Gravitee's roadmap to govern agentic interactions positions it at the intersection of API management and AI infrastructure — an emerging category with significant enterprise spending implications. Its combination of open-source credibility, broad protocol support, and growing AI governance capabilities makes it a compelling platform for enterprises navigating the complexity of modern distributed architectures.
