Monomi Park

Monomi Park is an independent video game developer and publisher based in San Mateo, California. Founded in 2014, the studio creates and self-publishes original games, with its work centered on the Slime Rancher series. Its games combine first-person exploration, sandbox play and simulation with colorful 3D worlds and whimsical character design.

The studio’s debut, Slime Rancher, brings together farming simulation and exploration. It entered early access in January 2016 and reached its full release in August 2017. The game subsequently grew into a substantial international franchise, with more than 17.5 million copies sold across platforms and over 19 million players worldwide. Its platform history includes PC, macOS, Linux, Xbox One and PlayStation 4. In August 2021, Monomi Park released Slime Rancher: Plortable Edition, an optimized Nintendo Switch edition that brought the game to another console audience.

Slime Rancher 2 continued the series, entering early access on PC and Xbox Series X/S on September 22, 2022. The sequel sold more than 100,000 copies within six hours and exceeded 300,000 copies during its first week. It expanded to PlayStation 5 in June 2024 and reached its full version launch on September 23, 2025.

Monomi Park operates as an original intellectual property creator, managing development and publishing internally rather than offering external client work-for-hire services. Its capabilities span game design and production, software engineering, physics simulation, multi-platform porting and live operations. Community management, digital publishing, merchandise design and brand management support the studio’s releases beyond their initial launches. This operating model connects the creation of its games with their ongoing distribution, audience support and wider brand activity.
