CO2OPT is developing a collaborative web application to fully digitalize tire management for heavy vehicle fleets from end to end.

The platform is designed to optimize both CO₂ emissions and the operational costs associated with tire management today.

We follow a remote-first, API-first development approach that enables seamless data exchange and supports lean, modular architectures instead of heavy monolithic systems.
