Mizu 2026: Make Commercial the Default

AI tools like Cursor and Claude have collapsed the cost of building software, allowing anyone to ship a product in days. Yet, the path from product to business remains fragmented and slow, trapping 99% of builders at $0 revenue. Mizu aims to fix this broken link. It acts as an automated CFO and CMO for AI-native founders, handling everything from instant incorporation (LLC & EIN) and banking to executing growth strategies like technical SEO, paid ads, and affiliate management. The vision is simple: Cursor builds the product. Mizu builds the business.
