Silexica today announced that it has raised $18 million in venture capital to further develop its suite of software tools for self-driving vehicles.

Based in Cologne, Germany, Silexica offers a software product called SLX that helps companies manage the creation of complex software needed for sophisticated use cases, like autonomous cars. Silexica was founded in 2014 and has now raised a total of $28 million.

“We created SLX to support software professionals facing the biggest challenge in the industry — programming heterogeneous supercomputers,” said Silexica CEO Maximilian Odendahl, in a statement. “SLX is truly adding value to customers in delivering performance improvements and system insights on some of the most advanced computers being created.”

The company was cofounded by Odendahl, Johannes Emigholz, and Weihua Sheng. The group saw that traditional software testing tools were no longer able to keep up with the growing intricacy of high-level programs like the kind that run AVs or other embedded computing systems.

Silexica says it will use the money to continue developing SLX, as well as creating a platform that lets industrial users run complex simulations to better understand how software will behave before it is deployed. The idea is to make the process of creating software for AVs and other uses more efficient and reliable.

The round was led by EQT Ventures Fund and included previous investors Merus Capital, Paua Ventures, Seed Fonds Aachen, and DSA Invest. The company has offices in Germany, the U.S., and Japan.
