Spark Change is a high growth Fintech startup founded by executives in clean energy and technology, with backing from some of the world’s leading financial institutions. The company is on a mission to revolutionize access to carbon. More investors with access means a bigger impact on the environment. That doesn’t just change a world of investing. It can change the future of our planet.

Nominated FinTech Company of the Year at the 2019 Barclays Entrepreneur Awards, Spark Change has successfully built an entirely new system designed to eliminate the high costs and poor access that have become the status quo in the conventional financial industry. With the cost of climate change estimated to be $200bn a year, the company aims to shrink the world’s carbon footprint, for everyone’s benefit.

Invest in a cleaner world.
