Meshy, an AI 3D generation startup founded by MIT PhD Ethan Hu, closed a $400 million Series B round at a $1.5 billion valuation, marking the largest funding round to date for a company built specifically for generative AI 3D content. The round was co-led by IDG Capital, Matrix Partners China, and Monolith, with all existing investors including Sequoia China oversubscribing. This is Meshy's first public valuation disclosure. The company reports 12+ million registered users, over 100 million 3D models generated, and customers at five of the world's top-ten tech companies by market cap.
Meshy has demonstrated unusual commercial traction for the category: annual recurring revenue has grown roughly 12-fold year-over-year with month-over-month growth consistently between 20-30%. The company compresses professional 3D modeling workflows from weeks to roughly one minute at ~$1 cost, achieving a 97% slicer success rate for production 3D printing. Alongside funding, Meshy unveiled its 3D Agent (conversational model-to-print workflow), Auto Split (one-click part separation for printing), and Smart Topology (native geometry in 10 seconds).
For game studios, 3D printing brands (Bambu Lab, Creality), and retailers building AI-assisted asset pipelines, this signals that generative 3D has crossed from research-demo to production-ready. The $1.5B unicorn mark and 12x ARR growth validates that 3D generation is moving from computational novelty to vertical application, with obvious leverage points in gaming, design, and manufacturing workflows.
