Have an idea to solve a climate problem?

Why we build startups

Women, youth, and historically marginalized people are continuously left out of the climate transition economy due to cultural, economic, and social barriers within the startup community. The result: climate “solutions” that ignore intersectionality and leave out the biggest stakeholders, the communities most affected. Everyone is needed for climate solutions that actually work for everyone.

Impact Zero supports climate startups from an idea to signing their first business customers. The proof of concept starts their momentum and provides critical learnings and skills to build sustainable climate businesses.

Not a founder? No worries!

We do work to inspire and lift up climate founders, including hyper-specific and one-on-one training to help founders connect their climate solution to business ROI for customers.

If you want to help a new founder get started, we encourage folks to make their own volunteer and advocacy role at work. Help convince your leadership to take a chance on a small pilot with a climate solution. By partnering with startups you don't pay for (or experience the pain of) R&D, thinking time, years experimenting, and deep training and expertise. There is lots to gain by getting in when the innovation is fresh!

Circular Marketplace

Our new and improved Circular Marketplace has been revamped to list your business and find circular versions of the products you need every day:

  • Search by product (i.e. search for “totes” and see who sells them)

  • Learn about what makes each business circular

  • Filter search results by location & business owner identity

  • List your business so folks who want to support you can find you!

Sponsorship Opportunities

If you work at a company that wants to connect with innovators or climate conscious consumers, we like to have an excuse to get everyone together!

Whether you want to educate the public about circular economy or other climate topics, or showcase your own innovative solution - we can get the right people together to harness the power of community to spread awareness about values-aligned work.

We want to launch 100 climate startups in 2025

but we can’t do it without your support!
