Revolt, founded in 2017, is based in London with operations in New York. The company has roughly 70 employees.

Anthesis Acquires Revolt: Executive Perspectives on the Deal

In a prepared statement about the deal, Anthesis CEO Stuart McLachlan said: “Anthesis exists to guide our clients as they transition to decarbonised and more sustainable futures. The development and activation of purpose-led strategies for C-suites and brands will be critical. With Revolt, we now have world-class expertise and experience in purpose consulting, strategy and communication. This, combined with our scientific rigour, our market-leading digital solutions, and the development of high-quality carbon removal projects, gives us the ingredients needed to manage risk and find value for our clients in their transformation journeys. I’m delighted that we have assembled all these interdependent and vital components into one team focused on delivering positive impact.”

Alex Lewis, co-founder, Revolt

Added Revolt Co-founder Alex Lewis: “The promise of sustainable impact is within reach, but getting there is difficult for brands and businesses to navigate. Many of those struggling with this complexity find that traditional consultancy and agency models aren’t built to help them adapt. To urgently scale purposeful impact, it is becoming increasingly important for the science, the art, the technical and the strategic to come together. This is why we are delighted that our second chapter will be as part of the Anthesis family. Together, we have a unique opportunity to accelerate this sustainable transformation for clients new and old.”
