Built by Bitcoiners

As bitcoiners, we have found ourselves in situations where we needed money for investments or personal use. However, we never felt comfortable handing over our bitcoin collateral to a centralized lender. That is why we launched Firefish - a bitcoin-backed lending platform based on decentralization, and ease of use.

Martin Matejka, Igor Neumann – founders
