Elon Musk has founded or co-founded multiple high-impact companies that span space, AI, electric vehicles, tunneling, and social platforms. Some he still runs; others he's stepped back from. Here we explore the major organizations he founded, what each does, and how they connect to his broader vision.
What early ventures set the stage?
His entrepreneurial journey began with Zip2 in 1995, a software startup with his brother. It provided online city guides for newspapers. He sold it in 1999 for about $300 million. The capital from Zip2 helped him found X com.
