Ehsan's Growth Take
Luminance built their own LLM for legal instead of wrapping GPT. That sounds like NIH syndrome until you see the results: their model handles legal nuance that general LLMs miss, particularly in cross-jurisdictional work. On a 500-document M&A diligence exercise, Luminance completed first-pass review in 24 hours. The same review took a team of 6 associates two weeks. The math is not close.
