Our product

Wren is a web app that makes it easy for anyone to calculate and offset their carbon footprint through a monthly subscription. Through a series of questions, the website calculates your carbon footprint and offsets your emissions so you can live climate neutral.

Subscribers choose to offset through a specific project, and then monthly updates are sent showing the progress their project made, like photos of the trees planted or satellite imagery of the rainforest protected.

You can see what's next for our product on our public roadmap. Our product is still early and there's a lot we want to add. Maybe you can help us!

Our mission

Wren's mission is to help end the climate crisis.

We plan to do this by empowering individuals. Individuals are the atoms that make up society. We need systemic change in order to mitigate the climate crisis, and systemic change comes from individuals.

Wren is a mission-driven business backed by mission-aligned investors like Y Combinator, Union Square Ventures, LocalGlobe, and many wonderful angel investors, including Paul Graham and Yancey Strickler.

We wrote a charter that we hope to make legally binding as we reincorporate as a Public Benefit Corporation this year. In the charter, we commit to being radically transparent, always evaluating our own effectiveness, and being a role model for how corporations should act. These are values that we expect every member of the Wren team to uphold.
