Casetext got there first, launching in 2013 — that's 2 years of extra runway. Luminance didn't arrive until 2015. In AI, that kind of head start means more training data, deeper customer relationships, and a bigger talent moat.

Luminance has about 150 employees; Casetext has about 120. 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 Luminance and Casetext compete in AI Legal, targeting many of the same buyers. If you're evaluating one, you should be looking at the other.
