Gamebeast raised $3.7M to build tools that change Roblox games live (interview)

Gamebeast sells Roblox developers tools such as A/B testing and LiveOps to modify running games without releasing a new version or interrupting players.

That Roblox developers will pay for A/B testing and LiveOps tools that change games without a new release — enabling UGC creators is where gaming growth is.

$3.7M pre-seed led by J2 Ventures with participation from a16z's Speedrun accelerator.

Brumbaugh said he started on Roblox at 12, teaching himself to program in Lua; he later consulted for entertainment studios like Netflix and wrote a best-selling book on Roblox development before founding Gamebeast.

He graduated from a16z's Speedrun accelerator in March and raised a $3.7M pre-seed. The round was not only a UGC bet: TechCrunch reported J2 Ventures' thesis focuses on dual-use technology, and Gamebeast demonstrated how its tools have applications in both commercial and defence settings.

UGC platforms like Roblox make content creation easy from a young age, swelling the pool of developers who need production-grade tooling.

Live-ops and A/B testing tooling monetises every existing creator-built game rather than gambling on hit titles.

A dual-use commercial-and-defence story widened the investor pool for a gaming-tools pre-seed.

Selling picks and shovels for a creator economy — tooling for UGC makers — rides a platform's growth without betting on any single hit game.

As of 2024-10-09, Gamebeast had a $3.7M pre-seed led by J2 Ventures with a16z's Speedrun participating, and Brumbaugh was building Roblox developer tooling; traction figures beyond the round were founder statements in the interview.
