Passbolt Raises $8M Series A led by Airbridge

We have started 2025 at full speed and are excited to announce our strategic investment in Passbolt, an open-source credential management platform designed to enhance security and collaboration for modern teams. Headquartered in Luxembourg, Passbolt has quickly become a trusted solution for over 400,000 daily users in 35,000 organizations worldwide, including governments, defense agencies, and IT companies across more than 50 countries. Passbolt was co-founded by Kevin Muller (CEO), Rémy Bertot (CTO), and Cédric Alfonsi (CPO).

Passbolt's unique approach to password and security management—available both on-premise and in the cloud—emphasizes end-to-end encryption and a public-private key architecture, ensuring that teams can securely share and manage their credentials. Its versatility allows seamless integration into various workflows, making it an invaluable tool for IT professionals, DevOps teams, and organizations prioritizing security and privacy.

Passbolt operates on a freemium-premium model driven by the open-source community, which helps it achieve widespread usage. Premium features encourage conversion to paid plans, and customers consistently express their satisfaction with Passbolt, as evidenced by its low churn rate, extremely high net retention rate (NRR), and impressive net promoter score (NPS).

This investment aligns with our commitment to supporting pioneering technologies that address critical cybersecurity challenges. We are particularly impressed by Passbolt's dedication to openness, security, and user-centric design, which has fostered a robust community of users and contributors. We are excited to collaborate with Kevin, Rémy, Cédric, and the entire Passbolt team to accelerate their Product-Led Growth strategy further, expand their product offerings, and explore new markets.

We look forward to a successful partnership with Passbolt and are confident that we will make significant strides in enhancing cybersecurity for organizations globally.
