About Us Self-custody
Self-custody is a fintech company committed to acting as a “bridge between corporations and individuals.” By providing a SaaS-based core financial infrastructure system, we enable embedded finance for businesses. We drive financial DX (digital transformation) to lower the barriers for non-financial companies to offer financial services — with the ultimate goal of making finance more integrated into everyday life.
We rethink financial services from the user’s perspective, and collaborate with partner businesses to develop new financial services.
