Zach Letter

Zach Letter spent over a decade as a full-time YouTube creator with billions of views before founding WonderWorks, the Roblox studio behind SpongeBob Tower Defense — the highest-earning licensed game in Roblox history. He treats a game's launch as 'chapter one,' runs relentless weekly LiveOps with a deliberately small, owner-minded team, and once bet the entire studio on a single six-week licensed build to survive a near-collapse.
