Four cofounders of Cursor, all in their mid-20s, are now billionaires. The AI coding startup’s merger into a freshly public SpaceX has turned what was already an extraordinary paper fortune into something far more liquid and far more real.

The path from MIT dorm room to ten-figure net worth took roughly four years. For Michael Truell, Sualeh Asif, Arvid Lunnemark, and Aman Sanger, the timeline was compressed by a product that developers actually wanted to use and a buyer with very deep pockets.

From $29B valuation to $60B acquisition

Cursor, officially incorporated as Anysphere Inc., was founded in 2022. The company builds AI-native coding tools, which is a fancy way of saying software that helps developers write code faster using artificial intelligence.

In November 2025, Cursor raised $2.3 billion in funding at a $29.3 billion valuation. Each of the four founders holds approximately 4.5% equity, which at that valuation put their individual stakes at roughly $1.3 billion apiece.
