Shenzhen is home to a lot of startups. some of them become unicorns, many of them you'll never hear about unless you're ij that specific market because they're B2B or get rebadged in Western markets. But there's a tooon of startups in every domain there. Basically most of the ebike market for example will use a lot of components from Shenzhen startups, and so do most electronics and a lot of software and e-commerce.
