Investigation found Elon Musk's Tesla owes dozens of small businesses millions of dollars in unpaid bills.

When Jennifer Meissner’s small pipe welding business landed a multimillion-dollar contract to help build a sprawling new Texas headquarters for Tesla, she was convinced it was her company’s big break.

Instead, she says the deal led her into personal and professional bankruptcy – unable to pay dozens of her workers at Christmastime. Meissner said that was her last resort after Tesla, which is owned by the world’s richest man, stopped paying her company for work they’d already done.
