About Scope3

Scope3 is the industry’s leading collaborative sustainability platform. By modeling the complex digital advertising supply chain, we help brands measure and dramatically reduce digital waste to reduce carbon emissions from advertising and increase the efficacy of advertising investment. This is an exceptional opportunity to build a company alongside great people and make a difference in one of the most important issues facing the planet: the climate crisis.

We’re a venture backed company of 65 folks distributed across the globe. We are fortunate to be led by an experienced leadership team, many of whom designed and engineered the digital advertising landscape as we know it today. The company secured $20M in Series B funding led by GV in Oct 2023 (additional investors include Venrock, Rucker Park, Room40 Ventures, and Craft Ventures), and we are thrilled to be the recipient of an additional round of $25M in Oct 2024. Scope3 has significant market traction with more than 150+ customers and is experiencing accelerated growth.

Scope3 is a fully remote company and largely asynchronous to provide flexible working hours and to operate globally, with concentrations in New York and Europe. At this time, we are hiring in Canada, Australia, UK, France, Germany, and the United States.
