This aerial photograph taken on January 14, 2026 shows the building housing the headquarters of Chinese AI startup DeepSeek in Hangzhou, in China's eastern Zhejiang province. Before DeepSeek shook up the tech world and put Chinese AI on the map, Wu Chenglin's own startup DeepWisdom had nearly folded three times -- but in the past year it has raised $30 million.
