The story

Founded as Demosphere International, Demosphere built out a broad youth sports management platform covering club management, league management, roster tools, and online registration with embedded payments. The company added insurance (via Vertical Insure) and payments infrastructure (via JustiFi) to monetize its sports-organization customer base beyond SaaS subscriptions. In 2025 the company rebranded to OTTO SPORT AI, signaling a pivot toward AI-powered communications and operations tooling, and raised $16.5M in seed funding to accelerate that transition.
