Luminance got there first, launching in 2015 — that's 5 years of extra runway. Spellbook didn't arrive until 2020. In AI, that kind of head start means more training data, deeper customer relationships, and a bigger talent moat.

Luminance has about 150 employees; Spellbook has about 75. 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 Spellbook compete in AI Legal, targeting many of the same buyers. If you're evaluating one, you should be looking at the other.
