Revel Software Corp., a Los Angeles-based startup that develops software tools to help engineers test complex physical systems more efficiently, has raised $150 million in Series B funding. The round was led by Index Ventures, with participation from Redpoint Ventures, Thrive Capital, Felicis, and Abstract Ventures, as well as several angel investors including Figma CEO Dylan Field. Revel's software platform, which includes tools like RevelTest and RevelC2, aims to automate and accelerate the testing workflows for advanced systems like jet engines, robots, and space launch vehicles.

Why it matters

As physical systems become increasingly complex, the testing and validation process has become a major bottleneck in their development. Revel's software promises to streamline this workflow, potentially speeding up the time it takes to bring new technologies to market in industries like aerospace, energy, and robotics.

The details

Revel's software tools focus on automating the data collection and analysis aspects of physical system testing. Its RevelCode language, based on Python, allows engineers to more easily define test parameters and detect anomalies. RevelTest can then overlay detected issues on simplified system schematics, providing real-time feedback. The company says its tools can reduce the typical months-long test development process down to just a few hours.
