Flank

Legal OS GmbH, based in Berlin, Germany, specializes in AI-driven legal solutions that enhance compliance and information security workflows for mid-size and enterprise organizations. Legal OS GmbH was founded in 2019 and operates under the brand Flank, providing autonomous legal AI solutions. The company has completed four deals, with its latest funding round, Series A, raising USD 10. 000 mn on January 14, 2025, led by Insight Partners.

The founders include Charlotte Kufus, Jake Jones, Lilian Breidenbach, and Tom Brooke, who have a background in technology and entrepreneurship. Flank delivers an autonomous legal AI solution that optimizes legal, compliance, and information security workflows for mid-size and enterprise organizations. Central to its offering are AI agents that assist in drafting and reviewing non-disclosure agreements (NDAs), data processing agreements (DPAs), vendor contracts, and compliance questionnaires. These agents integrate with platforms like Microsoft Teams, Slack, and email, facilitating seamless user interaction.

The service is designed for legal and compliance teams, automating repetitive tasks and improving efficiency in document processing across sectors such as technology, finance, and healthcare. Flank primarily generates revenue through subscription models that enable organizations to incorporate its AI agents into their operations. Clients typically sign annual contracts for access to the platform and support, with a pricing structure that scales based on the organization's size and complexity. This model is intended to provide a cost-effective alternative to traditional legal services, particularly for flagship offerings like NDA and compliance form management.

In January 2025, Legal OS GmbH secured USD 10. 000 mn in Series A funding to enhance product development, expand engineering and commercial teams, and strengthen enterprise partnerships. The company aims to launch new product features and expand its presence into North America, Europe, and select markets in Asia by 2026.
