Ready to join the green games revolution?

We’re on a mission. With 15 million tonnes of carbon emitted by the games industry each year (which excludes the much much larger user-end emissions), we felt like something had to change. We realised we had to solve the problem at the core & fundamentally change how people create software & how users treat their hardware.

Jeco is building automated optimisation tools for all software, on any device, as well as advanced power/carbon monitoring tools - empowering both developers and users to save costs, energy & carbon too.
