CapSign is the protocol for capital markets & digital assets.
Our mission is to enable more opportunities and greater economic benefits for private companies, shareholders, and investors through blockchain technology. We believe that interoperability will be a major driver for compliance automation, deep liquidity, and composability between financial services. We're focused specifically on private markets by improving workflows for transactions involving restricted securities.
As a young startup, our tech stack is optimized to allow us to ship at hyperspeed. As we mature, we envision adoption of technologies that are more optimized for the platform.
