Thornby
Thornby reads contracts the way a junior associate would, then shows its working so the senior lawyer can disagree with it quickly.

What we saw in Thornby.
Legal AI is crowded, and most of it fails the same test: a partner cannot see why the model reached its answer, so the review takes as long as doing the work.
Aisha practised for six years and built the citation trail before she built the model. That order matters.
We invested knowing the category would attract far larger competitors. Thornby wins on how it handles disagreement, which is harder to copy than accuracy.
The company in short.
