Cosmonic Raises $8.5 Million in Seed Round

by Kay Aloha Villamor in October 26th, 2022

Cosmonic, an Arlington, VA-based WebAssembly (Wasm) pioneer, closed $8.5 million in a seed funding round led by Vertex Ventures.

Joining Vertex's General Partner In Sik Rhee in this early round is Meta advisor (and Facebook's ex-VP infrastructure engineering) Jeffrey Rothschild; WebLogic and funding syndicate founder Bob Pasker; Jeff Burkland (founder of financial consultancy Burkland Associates); Tom Killalea, chairman of the MongoDB board of directors, and VC firm General Advance.

The round is also supported by Cosmonic co-founder and CEO Liam Randall's Relentless VC. The terms of the deal were not disclosed.

The funds will be used to accelerate the development of Cosmonic's Platform-as-a-Service (PaaS), a lightweight suite of Wasm-powered tools, features, and services that radically abstract complexity from application development and management. 

"We are on a mission to bring back joy to the art of developing cloud-native software," said Liam Randall, co-founder and CEO of Cosmoniic, "The complexities of building modern distributed applications have brought developer productivity to a crawl, adding friction and unnecessary complexity to every stage of the development life cycle. This funding round will enable us to support developers working in early-stage, rapid and interactive environments -- allowing them to transform applications from napkin sketch to scale in minutes. Future releases will offer the advantages of high reliability and lower long-term software maintenance costs."

Cosmonic is built atop wasmCloud, the fast-growing Cloud Native Computing Foundation (CNCF) sandbox project, and the universal platform for composing distributed applications from portable business logic that runs anywhere, at any scale. 

wasmCloud eliminates 95% of code and entire classes of development challenges by treating non-functional application requirements (e.g., databases, servers) as composable components behind an abstraction. Launched in November 2020, wasmCloud has grown quickly to include over 100 core contributors and was accepted as a Cloud Native Computing Foundation (CNCF) sandbox project in August 2021.
