What We Do

Libra is a category-defining, venture-backed generative AI startup. We’re building the infrastructure for the legal system of tomorrow.

In today's world, more people have access to the internet than access to justice. The advent and rapid advancement of large language models offer an unprecedented opportunity not only to automate legal services, but to disrupt the whole industry. That’s why our mission is empowering every claim owner to make a full use of their rights.

We’re developing a claims drafting factory, which will automatically produce legal claim packages using AI. This will allow us to deliver an easier, more efficient, and higher quality legal service for customers.

As a fast-moving venture, we’ve closed three pilots with prominent enterprise customers and raised 1mln EUR in a pre-seed investment from Merantix, Europe’s leading specialist AI Fund. Now we’re growing the team to make our vision a reality.
