  • 9Zero is for Innovation builders. Within the broad scope of Innovation & Climate, we create interconnected mini-ecosystems to accelerate growth. Our clusters focus on specific sub-sectors where industry experts, founders, investors, and operators can find eachother and collaborate. Don’t see your sector represented yet? As a member, you can launch a new cluster!


    Whether you’re building a company, a fund, policy, a community, or something else, if you’re working on climate solutions, tell us more about how we can help.

  • We host events 2-6 times a week! All our events are by members, for members. Seattle AI builders, Seattle Energy professionals, Seattle sustainability leaders, throwing events to bring your career or company to the frontier. Before you join, we invite you to attend up to 3 events.

    See upcoming events here:

  • As a first step, we’ll ask you to tell us a bit more about what you’re looking for. Joining a community is an investment, and we want to make sure there is a mutual fit!

    The next step will be coming in for a visit and meeting some members of the community. We’ll answer any questions you have and get you set up with the membership that best fits your needs!

  • It’s helpful to have a sense of what kinds of folks you’d like to meet, and to explore our resources, like:

    • Member directory

    • Slack channels

    • Clusters

    • Events

    • Our staff and community superconnectors

    At the same time, we find that often the best things are those you couldn’t have planned for. The more you invest into the community–attending and organizing events, introducing yourself to new people, and sharing your expertise–the more you’ll get back in return.
