How Mint Reached 40,000 Users in Two Months Using Convex

Alex Carrabre of Founders, Inc. discusses Mint, a platform that provides tooling, or a “harness,” for AI world models that turn text or images into navigable 3D environments usable in areas such as gaming, architecture, construction, visual effects, and event planning. Mint emerged after the team shifted away from crypto products, despite earlier applications reaching more than 100,000 users, because they believed the crypto label discouraged adoption; an on-chain room-customization project and early access to World Labs’ API led to the new product. After pivoting and adopting Convex as its backend, Mint reportedly grew from zero to 40,000 users in two months, and the team credits the platform’s speed and low latency while focusing next on improving its chat experience and expanding integrations, including a recently released MCP. Carrabre characterizes the venture as a bet that world models will eventually find product-market fit, though the leading application remains uncertain, and positions Mint as infrastructure for whichever use case succeeds. He emphasizes launching early and learning from real user behavior rather than delaying release in pursuit of a product founders assume is perfect.
