Show HN: We Open Sourced a $50M Neobank

At Hack Club, we've always been committed to transparency. Since our launch in 2018, we've expanded our reach beyond just hackathons, opening up our fintech platform, HCB, to all nonprofit projects. Today, we're excited to announce that we've taken the next step: making our $50M neobank fully open sourced.

Our journey began with a simple goal – to empower nonprofit groups, student teams, and community organizations to raise and spend money through fiscal sponsorship. We've seen firsthand the impact HCB has had on these groups, allowing them to collect donations, send payments, issue debit cards, and even gain 501(c)(3) status. With over 12,000 users, we've achieved a remarkable $50 million in transactions – a testament to the power of open source fintech.

We started HCB in private for security reasons, but transparency has always been at the heart of our mission. We document every event, publicly share our finances, and have over 500 public repositories on GitHub (now public!). Our technical documentation and engineering work are also entirely public, allowing anyone to learn from our successes and mistakes.

Since 2018, more than fifty people have made over 10k commits to HCB. We're proud of the community that's grown around our platform, and we can't wait for even more contributors to join us. If you're interested in building financial software or applications with Ruby on Rails, check out our GitHub repository (github.com/hackclub/hcb). We're committed to making it easy for anyone to get involved.

But that's not all – if you're looking to start a nonprofit, we've got resources to help. Our nonprofit platform is here to support you every step of the way. Head over to nonprofit.new and we'll be in touch to discuss how HCB can help your organization thrive.

We're excited about this new chapter for Hack Club and our open sourced neobank. Join us on this journey and let's work together to make a positive impact around the world!
