About
WunderGraph builds open-source GraphQL Federation infrastructure for platform teams. The company's flagship product, WunderGraph Cosmo, provides full lifecycle API management for federated GraphQL systems with schema registry, composition checks, analytics, metrics, tracing, and routing capabilities. Founded in 2020, WunderGraph has established itself as a drop-in replacement to Apollo GraphOS, offering the only open-source solution that combines enterprise-grade governance with developer-friendly tooling. The company raised $7.5 million in Series A funding led by eBay Ventures in March 2025, enabling rapid expansion of its globally distributed team across 10 countries and 18 nationalities. WunderGraph serves enterprise customers including eBay, SoundCloud, Acoustic, and Luxury Presence, delivering solutions that unify API infrastructure across GraphQL, REST, gRPC, and Kafka protocols with a focus on performance, security, and compliance standards like SOC 2.
