Autodesk's founder thought computer drafting was a niche, then AutoCAD took off
In 1982, John Walker and fifteen fellow programmers pooled $60,000 and planned several software products to see which would stick. Walker doubted design software could be big, since architects were far fewer than people writing documents. Then AutoCAD drew crowds at Comdex while their text editor drew shrugs, and the company never looked back.
AutoCAD began life as Interact, a drafting program written in 1979 by Michael Riddle, who had struggled to sell it and agreed to hand it to Walker for royalties. It ran on inexpensive microcomputers, including the new IBM PC, which put detailed technical drawing within reach of small architecture and engineering firms. Released in December 1982, it brought in $1.4 million during its first year, and Walker said the company was profitable from its first month without loans or outside investors.
Growth was rapid. By December 1984 about 10,000 copies were installed, and AutoCAD was so famous that for a while the firm let people assume that was its name. Autodesk went public in 1985, a process Walker compared to lying on the beach or juggling chainsaws, and by 1989 sales exceeded $100,000,000 after just four years of operation. A 1986 release added a built-in Lisp language, letting outside developers tailor the program for specialist trades.
Walker stayed on as a programmer until 1994, leaving after disagreements over the company's direction, while chief executive Carol Bartz ended its wanderings outside design software. Autodesk broadened through acquisitions, among them Revit, bought in 2002 for $133 million to model buildings virtually before construction, and entertainment tools such as 3ds Max and Maya used in film effects and games. Its DWG and DXF file formats became common currency for sharing design data.
The software has been used on projects from One World Trade Center to Tesla cars. In 2022 the headquarters moved to San Francisco from San Rafael, its home since 1994, and in February 2026 Autodesk announced a $200 million investment in World Labs, which builds AI models that generate interactive 3D worlds.
