WunderGraph develops Cosmo, an open-source GraphQL federation designed to address API sprawl by unifying GraphQL, REST, SOAP and databases. The company sells hosting, premium support and professional services, including help with database integration, analytics, authentication and observability. Cosmo was debuted in late 2023 as an open-source alternative to Apollo’s proprietary federation offering. WunderGraph plans to grow its roughly 20-strong workforce and double down on tools that improve collaboration and governance for distributed teams at large enterprises. The firm previously built an SDK and raised a $3M seed round in 2023 to pursue a “GitHub for APIs” vision. The company emphasizes open source licensing to attract large customers seeking transparency, flexibility and control. WunderGraph provides an open-source framework that automates much of the work involved in building APIs and generating Backends-for-Frontends from a single data pane. The platform creates a unified API across services and databases so developers can produce tailored backends for websites, apps, and other data consumers with a single command. Led by CEO Jens Neuse, the company maintains offices in Miami, FL and Frankfurt, Germany. WunderGraph is used by developers at companies such as Tripadvisor and Mr.Yum and has partnerships with technology providers including Oracle, Fauna, and Auth0. The company closed a $3M Seed funding round and intends to use the proceeds to grow its team and expand its global user base.
