Windwalk

Founded in 2018 by Colin Feo, Cris Feo, and Samuel Leonard, Windwalk is a game development studio that initially started in a San Francisco living room. The founding team possesses a strong background in technology and gaming; CEO Colin Feo holds a computer science degree, gained experience at Riot Games and Baobab Studios, and is a Y Combinator alumnus. This collective expertise propelled their early efforts to develop a prototype for their first game, which led to their acceptance into the Y Combinator accelerator program in Winter 2019.

The company’s initial focus was on creating online multiplayer games centered around community engagement. Their first title, "Enemy on Board," released in May 2020, is a free-to-play social deduction game where crew members on a spaceship work to identify and eliminate alien impostors among them. Following this, Windwalk developed "SWORN," a cooperative action roguelike game set in a fallen Camelot, which launched in early 2025. This title allows up to four players to team up against a corrupted King Arthur and his knights.

Recognizing a broader market need from their own experience with game promotion, Windwalk pivoted to a new business model. The challenges of gaining attention with a small team and budget inspired the creation of tools to foster growth through word-of-mouth and superfan engagement. This led to the launch of Harbor, a social software platform designed to help companies unify and engage their most passionate users. Harbor provides no-code visual dashboards that allow partners to integrate their social audiences, manage community events, and gain a holistic view of their fandom. This strategic shift was supported by a $4.5 million funding round from investors including a16z SPEEDRUN, Tirta Ventures, and YCombinator. During its closed beta, Harbor generated over five million monthly active users for partners like Scopely, Immutable, and NZXT, validating its business-to-business model.
