We build software,


We specialise in building web, mobile and desktop applications that are optimised for power consumption and carbon emissions.

Our green software expertise helps startups and scaleups bring digital products to market on a low carbon trajectory, enabling them to grow rapidly with sustainable technology at the heart of their business.

Software's dirty secret

Digital technologies are a major source of greenhouse gas emissions globally. Although hardware produces these emissions, software drives the demand. We must change how we build software and reduce the environmental impact on our planet.

Emissions from ICT are greater than those from aviation, which are around 2% of global emissions.

Our Story

We are software developers and friends who share a curiosity for code and a care for climate. Back in 2022 we had a conversation that changed everything for us. It arose from a simple question: what is the carbon footprint of our software?

The months of research that followed led us to the conclusion that our digital world negatively impacts our environment on a shocking scale. Addressing this requires root and branch change to the way we develop software.

Our company was founded in 2024 as a commitment to building software sustainably and helping others do the same.
