The company
Melty is building an AI-powered platform that lets users 'mashup any game' — creating new or modified gaming experiences by combining and altering elements from existing titles. The San Francisco startup is pitching this as a route to custom, user-generated games rather than yet another standalone studio.
AI tooling has lowered the barrier to generating playable content, while modding and user-generated worlds have moved from niche hobby to a core driver of gaming engagement. The timing lines up for a platform that puts creation in the hands of players, not just studios.
The company was founded by David Miller, who previously coached millions of gamers — a background that could feed naturally into coaching and analytics features alongside the core mashup tools. Melty is part of Y Combinator's Fall 2026 batch.
Miller's track record coaching gamers at scale gives the founding team a direct line to the player community it wants to serve. For an early product that lives or dies on what players actually want to build, that proximity matters.
