About the Company

Cerulion was founded in 2024 by MIT PhDs to modernize robotics. Having grown tired of ROS and utterly abysmal quality of life for robot devs, we are making a backwards-compatible open source robot middleware. We raised a pretty successful seed round from top tier investors and are looking to build a passionate team for the mission.

Tech Stack

We use Rust for the core middleware code, and offer C++, Python and Rust endpoint APIs for developers. Frontend visualization uses the Godot game engine.
