About WunderGraph 

  • WunderGraph is a German and US-based software company founded in 2020 by Dustin Deus, Jens Neuse, Björn Schwenzer, and Stefan Avram. The company specializes in API integration and automation. 

  • It provides a unified platform that makes it easier to connect different data sources, keep them safe, and manage them all in one place. This helps speed up and clean up how apps get and use data.

Thanks to its Cosmo Router tools, the company focuses on enhancing developer productivity and accelerating application development through automated API composition and deployment.

We’re excited to partner with the WunderGraph team as they set a new standard for the industry," says Tommi Uhari, Partner at Karma Ventures.

  • WunderGraph also offers hosting, premium support, and services, including database integration, analytics, authentication, and observability.
