Get ready to hack the law
and to enable knowledge!

Join the Lefebvre Sarrut teams for a unique opportunity to explore the possibilities brought by generative AIs (e.g. ChatGPT) to the fields of law. Experts from all across Europe will gather to collaborate, innovate and facilitate the professional services (lawyers, accountants, HR managers, and many others!) in a fun, exciting and safe environment.

A hackathon is an event where multidisciplinary teams gather to work on a challenge, and create the bases of a project. The teams follow a methodology and are coached all along the way by experts (UX designers, IT experts, designers, etc.) to bring their ideas to life.

3 Challenges

Activating knowledge for companies and their advisors 

Law, tax and regulations knowledge are the essential components of the Lefebvre Sarrut DNA – Matched with Generative Ai it can provide even more added value to companies and businesses.
With this challenge we’re looking for new ways to make knowledge easy to implement in every professional’s daily routine.

Revolutionizing legal writing 

Lefebvre Sarrut’s core activities are about understanding and sharing legal knowledge. Our writers, like other legal professionals, are expected to analyze content and share it with accuracy and efficiency under various formats.
With this challenge we’re looking for ways to empower them with AI and boost their writing activities.

Improving access to justice 

Law is an essential component of people’s life, but it seems very hard to apprehend and access. With this challenge we aim at exploring how Generative AIs such as Chat GPT can help breaking down the barriers they can face.
