Our mission is to accelerate our planet’s transition to a carbon negative society. We will capture 1B tons of CO2 from the atmosphere by 2035 (equivalent of ~60M Americans’ annual emissions today), and build a multi-billion dollar business along the way. The problem we are solving is that according to IPCC, billions of tons of CO2 need to removed from the atmosphere (in addition to decarbonizing the entire economy) by 2050 to keep global warming to 1.5 °C, but current technologies are too expensive and not scalable to the volume necessary.


Unlike traditional engineered removal solutions, our Nature published technology combines the natural properties of minerals (carbon mineralization) with engineering to provide a low cost path to $50/tCO2 for Direct Air Capture (DAC), the cost at which carbon removal will be transformative. 
Our early customers are corporations and other entities that need to reduce and offset their carbon emissions to meet compliance requirements or carbon pledges. Our go-to-market strategy allows us to be unit profitable from day one, and reach >$1B in revenue just from existing markets and pledges. Our $100B opportunity lies with carbon markets set for creation in the EU, US, and other markets. 


Over the next 18 months, we will de-risk our cost estimates, build our first deployment, and validate the commercial viability of this technology.
