Kuaishou got there first, launching in 2011 — that's 9 years of extra runway. HeyGen didn't arrive until 2020. In AI, that kind of head start means more training data, deeper customer relationships, and a bigger talent moat.

HeyGen has about 120 employees; Kuaishou has about 10000+. A bigger team usually means more revenue or heavier VC backing, but in AI, small teams can build at massive scale.

Yes — they're direct rivals. Both HeyGen and Kuaishou compete in AI Video, targeting many of the same buyers. If you're evaluating one, you should be looking at the other.
