Today present in more than 20 countries, the company, built around a team of more than 150 employees, mobilizes a large circle of French and international experts and partners.

Our collaborators and our partners

After successfully implementing several local energy and innovative pilot projects, I chose Tilia to help the public sector implement the energy transition. I appreciate Tilia’s continued and strong commitment to helping his clients develop innovative projects that add value to their regions. Tilia mobilizes technical, financial and legal expertise from its partners, coupled with extensive knowledge of the public environment and development of area projects.

Director of Territorial Communities Development

Tilia is not a typical consulting firm. The result of this really pleasant and professional cooperation: significantly improved cooperation in the entire company on IT issues, as well as proven optimization in IT organization and operation. I highly recommend Tilia for IT performance optimization and digitalization!
