3round

3round is a technology company specializing in decentralized identity and data management solutions. Founded in 2017 in Zurich, Switzerland, the company was established by three former engineers from a major cloud service provider. The founders’ experience in distributed systems and cybersecurity informed the firm’s focus on privacy‑first, blockchain‑integrated identity platforms.

The company’s flagship product, 3round ID, offers a self‑hosted identity server that supports OAuth2, OpenID Connect, and SAML 2.0 protocols. It can be deployed on-premises or in private cloud environments and includes a modular plugin architecture for integrating with existing enterprise identity providers. As of mid‑2023, 3round reports a customer base that includes several fintech firms, healthcare providers, and academic institutions across Europe and North America.

In addition to its core identity software, 3round has released a series of open‑source libraries for developers, notably a lightweight JavaScript SDK designed for single‑page applications. The company has also participated in industry conferences, such as the Identity Federation Forum, and contributed to several RFCs on decentralized identifiers.

Funding for the company has come from a combination of angel investors and a Series A round led by Swiss venture capital firm TechVentures in 2019. 3round maintains a lean operational structure, with a workforce of approximately 30 employees spread across Zurich, Geneva, and a remote team in Seoul. The firm’s stated mission is to enable secure, user‑controlled digital identities while promoting interoperability across disparate systems.
