Built by Wack Club

As Wack Club grew, we needed a way to empower our members. We currently have over 30,000 high schoolers involved in Wack Club with over 400 clubs around the world.

We started HCB in 2018 to support teen-led clubs and hackathons. After showing it to our educational partners, we knew we had tapped into something much larger. Today, HCB removes financial and legal barriers for thousands doing good in their community.

As part of our commitment to climate justice, funding for HCB’s operations and staff will never come from the fossil fuel industry.
