The Beijing-based 3D AI startup's planned Hong Kong IPO signals where big money is flowing, and it's not into tokensA 29-year-old founder, a billion-dollar valuation, and Alibaba’s checkbook. Vast, the Beijing-based AI startup behind Tripo3D.ai, is eyeing a Hong Kong IPO at a $2 billion valuation, roughly double what it was worth after its most recent private funding round. The marquee listings generating buzz in Hong Kong right now aren’t crypto exchanges or blockchain platforms. They’re AI companies like Vast, benefiting from a wave of Chinese tech firms seeking public listings. If Vast successfully goes public at $2 billion, having been valued at $1 billion just months earlier, it establishes a template that will encourage more AI startups to follow the same path.
