Make a Real Impact 🌍

Here at Treecard, We’re harnessing the power of the people to help solve climate change by building a platform to make sustainable living more accessible. We’re the kind of green that doesn’t wash off, and our customers have already planted over 5 MILLION trees just by being part of the Treecard community.

We’re striving to build the largest and most engaged eco-focused community and a worldwide organization people can trust. We need people who can’t wait to jump in and help scale our impact together.

Do the best work of your life 🚀

As a mission-driven startup, Treecard not only offers an environment for huge personal growth but an opportunity to leave a legacy we can be proud of.

We’re powered by Ecosia, the search engine that has planted over 130M trees to date and has over 30M monthly active customers. We've also raised $26M (Series A) to date and have a growing user base, with 40% of all sign-ups being referred by a friend or family. We are backed by EQT, Worldfund, and Seedcamp— the original investors of Transferwise and Revolut.

We’re set up for success, racing forward, and swinging beyond the fences. We are here to do the best work of our lives, and together, we hope you are too. Come help make sustainable living accessible for everyone.
