Luminance got there first, launching in 2015 — that's 7 years of extra runway. Harvey AI didn't arrive until 2022. In AI, that kind of head start means more training data, deeper customer relationships, and a bigger talent moat.

Harvey AI has about 200 employees; Luminance has about 150. 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 Harvey AI and Luminance compete in AI Legal, targeting many of the same buyers. If you're evaluating one, you should be looking at the other.
