Gamefam Studios is an American video game company. It primarily utilizes Roblox as a video game development platform, while also using Fortnite Creative and Minecraft as engines to create maps and minigames. It has produced content for brands such as Sonic the Hedgehog (Sonic Speed Simulator), the National Football League, Hot Wheels, Doctor Strange, Kung Fu Panda, Samsung, and Puma and staged virtual concerts for musicians such as The Chainsmokers and Saweetie.

Gamefam was founded in 2019 in Los Angeles, California, United States, by Joe Ferencz, the current CEO. Ferencz was originally involved with bringing Hot Wheels into the Forza series and Rocket League, and while doing so, he was observing Roblox's success as a free-to-play video game platform. Explaining his reason for founding Gamefam, Ferencz told TechCrunch, "Roblox truly is the Metaverse for this younger generation. What that means is that each game needs to have a very distinctive and attractive immersion to it, in a way that mobile free-to-play doesn’t." The company is described by Ferencz as the "first and only fully-dedicated, professional game publishing company on Roblox" and has recruited veteran Roblox developers.

In November 2020, Gamefam, with the partnership of Mattel, released Hot Wheels Open World on Roblox, which is a Hot Wheels-themed open world racing game.

In October 2021, Gamefam partnered with WowWee to create toys for their popular Roblox game Twilight Daycare.

In November 2021, Gamefam a partnership with WildBrain to start integrating various brands into their portfolio of Roblox titles.

In March 2022, Gamefam announced they have raised $25 million in its Series A funding round, which was led by Konvoy Ventures and participated in by Play Ventures, Makers Fund, Bessemer Venture Partners and Galaxy Interactive.

In April 2022, Gamefam, with the partnership of Sega of America, released Sonic Speed Simulator on Roblox, which is a Sonic the Hedgehog game. Its launch was the largest on Roblox, with 70 million plays and 275,000 concurrent players in the first week of its release, and it would reach 500 million visits in its first four months. Joe Ferencz called it "the No. 1 branded game of all time on Roblox".

In December 2022, former employees accused Gamefam of underpaying their employees while crunching them, as well as laying some off before the holidays without much warning, which was reportedly against the contract. Because the employees reported working on Sonic Speed Simulator while being mistreated, the hashtag #SonicSweatshopSimulator trended on Twitter as a protest by fans. Gamefam released a statement denying the accusations and began banning users who brought up them up in the Sonic Speed Simulator Discord server. In April 2023, Gamefam settled with an employee after he had filed a complaint to the National Labor Relations Board alleging that the company had violated the National Labor Relations Act by threatening retaliation against employees that spoke with coworkers about their salaries. The employee was paid $5,000 USD in bonuses and Gamefam was legally obligated to remind its employees of their rights.

This section may require cleanup to meet Wikipedia's quality standards. The specific problem is: Some terminology may need to be changed, as most tycoons and simulators on Roblox are incremental games instead of true simulation games and "obbies" tend to be mere platform games.
