Service Delivery Approach

The firm provides both advisory and litigation services, offering continuity from initial counsel through courtroom defense. Entropy represents clients before civil, commercial, and administrative courts, as well as regulatory authorities like the CNIL (French data protection authority). They analyze business models, products, and user journeys to propose both strategic overviews and pragmatic solutions to specific pain points.

Honoraires (fees) are set transparently with systematic quotes established before any engagement. The firm prioritizes fixed-fee packages adapted to each mission, with hourly billing only when intervention duration depends on external factors (negotiations, regulatory procedures, litigation). They also offer monthly subscriptions and dedicated formulas for startups.

The firm works at the intersection of law, disruptive technologies, and the development of tomorrow's norms to ensure clients maintain a competitive edge in their sectors. They serve major corporations, deep tech startups, digital companies, and public institutions that design or use cutting-edge technologies and need to secure their projects legally and regulatorily. The firm also collaborates with international partners in major technology ecosystems worldwide.
