London-based startup Tilt has built a livestream marketplace where sellers broadcast auctions in real time while viewers bid on everything from sneakers to designer clothing, beauty products, electronics, and collectible items. Rather than scrolling through static product listings, buyers interact directly with sellers, ask questions during livestream, and compete against each other in fast-moving auctions.

The concept is already creating a new class of Gen Z entrepreneurs.

“We had this 17-year-old who essentially started in his grandma’s bedroom and just scaled his whole business to over $100,000 within a few months,” cofounder Neil Shah told Fortune. “That’s a true testament that you’ve actually built something where people can go from zero to 100.”

Another seller, a 22-year-old named Maddie, turned the platform into a full-time business despite health challenges. Maddie, who is deaf and has fibromyalgia, sells niche streetwear brands. After initially reaching “upper five figures” in monthly sales, she surpassed $100,000 in June, according to the cofounders.

Those success stories aren’t isolated. Another sneaker seller generates roughly $260,000 in monthly sales, according to the company. These sellers are taking advantage of a global market, with bidding opening on nearly anything they decide to present on stream.
