Apollo has raised $130M in funding, valuing the company at over $1.5B, to pioneer open-source graph technology for app developers. The graph is a new layer of the stack that solves the problem of data plumbing code connecting apps to backend microservices, allowing client developers to write a single GraphQL query to fetch all the data they need. With 86% of JavaScript developers ranking GraphQL as the top technology they want to learn and over 17M monthly open-source downloads, Apollo has become a trusted solution for developers. The company plans to use the funding to create more open-source software, expand its offerings such as Apollo Federation, scale its team, and collaborate with the community on new projects. With a mission to help app developers help the world, Apollo is committed to advancing the graph technology and making it accessible to everyone.
