What Osponso does: → For rights holders (event organizers, clubs, federations, agencies): structure your offers, prospect sponsors, manage contracts, and track activations. All in one tool. → For advertisers: manage your sponsorship portfolio, monitor every activation in real time, and generate reports in just a few clicks.
