We created Terraton to remove carbon from the atmosphere. A lot of it. Not by waving a magic wand or inventing a new carbon capture technology, but by diving into the relatively boring and immensely practical side of climate change. Specifically, we create software that makes it easy to bring a new CDR facility online. We've created the first Carbon ERP solution designed to scale carbon businesses around the globe. Think of us as a carbon removal business in a box -- making CDR universal, accessible, and profitable.
