Ethyca Fides is a privacy engineering platform using an open-core model that embeds privacy compliance directly into technical infrastructure through Privacy-as-Code. Founded in 2018 by Cillian Kieran and Miguel Burger-Calderon, Ethyca takes an engineering-first approach that integrates with CI/CD pipelines, enabling developers to programmatically manage Data Subject Access Requests (DSAR), consent, and data mapping. The open-source core (Apache 2.0 license) provides self-hosted deployment, while Fides Enterprise offers cloud-hosted deployment with enhanced features, forward-deployed engineering teams, and enterprise support for organizations like New York Times, Mozilla, and Ramp.

The platform uses a machine-readable privacy taxonomy (the Fides language) to unify legal and engineering teams around shared definitions for consent, purpose, and lawful basis. Fides automates end-to-end DSAR fulfillment across hybrid cloud and on-premises environments, provides continuous data discovery and classification with ML-powered detection, orchestrates consent management, and enforces privacy policies in real-time across APIs and AI pipelines. The enterprise tier includes advanced SaaS connector integrations (700+ apps), cloud hosting, dedicated support, and deployment services.

Trusted by leading enterprises across technology, media, and financial services, Ethyca has raised $37.5M from Aspenwood Ventures, AVP, IA Ventures, and prominent angels including Des Traynor (Intercom), Guillermo Rauch (Vercel), Scott Belsky (Adobe), and Kevin Hartz (Eventbrite). The platform is recognized as the world's most widely adopted open-source privacy engineering solution, with 100% year-over-year revenue growth and enterprise customers switching from legacy providers like OneTrust and TrustArc.
