O3

O3 (O3 Platforms Limited) is a New Zealand-based company that builds and operates membership-based study cafes designed as social spaces for students, founders, and creatives. Founded in 2024 by Luca Yang in Auckland, the company combines physical cafe venues with a gamified mobile app that rewards members for showing up, enables in-venue social discovery, and provides 3 free hours of access per week. O3 participated in the Startmate Summer 2025 Accelerator and positions itself as a social network built around physical space, addressing loneliness and remote-work isolation.
