As a company, you can become a sponsor by supporting the projects carried by the Institut Henri Poincaré and the Maison Poincaré.

Supporting the Maison Poincaré means being recognized as an actor in the project and benefiting from tax advantages :


- French companies

  • Your company can benefit from a corporate tax reduction of 60% of the donation's value up to a maximum of 0.5% of its turnover excluding taxes in accordance with the law n° 2003-709 of August 1, 2003 relating to sponsorship, associations and foundations.

  • Your company will benefit from compensations according to the value of the contribution: availability of spaces for private events, privileged invitations for meetings, conferences, exhibitions...

You have the possibility to support the Maison Poincaré globally or to allocate your donation to a specific project. 

Your contribution will give rise to a sponsorship agreement that will detail the nature of your contribution and the terms of its contribution, whether one-time or long-term. 

You can also join the participatory financing campaigns that we regularly launch. The annual program The Maison Poincaré, math in a new light is online.
