You probably don’t know Tuya Inc.’s name. And that’s exactly how they like it.

Founded in 2014 by a former阿里巴巴 (Alibaba) engineer named Jerry Wang, Tuya isn’t a consumer electronics company. It is the world’s largest “AIoT” (Artificial Intelligence of Things) platform-as-a-service. Think of it as the Android of the physical world—a neutral, invisible operating system that allows a toaster in Shenzhen to talk to a thermostat in Toledo.

This "democratization of the smart home" led to an explosion. As of 2024, Tuya reported powering over 2,200 product categories and hundreds of millions of devices globally. They are the factory's best friend and the startup's shortcut.

Love them or fear them for the data they hold, one thing is certain: Tuya solved the hardest problem of the Internet of Things. They made it boring. And in technology, boring infrastructure is the most interesting thing of all. You don't see Tuya; you just feel the convenience. And that, ironically, is the mark of a company that has already won.

But here is the twist: Tuya is smarter than a light switch. They realized that selling modules for smart bulbs is a low-margin game. The real future is "SaaS" (Software as a Service) for businesses.

In 2021, Tuya went public on the NYSE (ticker: TUYA) with a valuation near $14 billion. Then came the "smart home winter." Supply chain shocks, the US-China tech war, and consumer fatigue hit hard. The stock plummeted.
