Instacart's new valuation of up to $9.3 billion is a massive down round from the $39 billion of a few years ago. Bill Gurley, a VC and early Uber investor, says that’s a healthy reset: "I've lived through 3 different bubbles and bursts in this industry and unfortunately it's highly cyclical. It tends to go up slowly and crash immediately." He also talked startups in the IPO pipeline, whether there’s an AI bubble, and more.
