Osponso is a Nantes-based startup offering a software platform that streamlines the management of sponsors, donors, and partners for sporting and cultural events such as races, festivals, and association activities. The tool centralizes workflows so organizers can track commitments, benefits, and reporting in one place. With its newly raised capital, the company plans to strengthen its staff, add features to its existing product, and launch a dedicated vertical aimed at advertisers. Although detailed operating metrics such as revenue or user counts were not disclosed, the raise indicates growing demand for digital solutions in the fragmented sponsorship market. The company’s immediate financial focus is deploying the €400 000 to accelerate product development and market expansion. Its positioning targets both event organizers and, soon, advertisers seeking streamlined partnership management.
