Welcome to Crosby, the next-generation law company!

We're a team of technologists and legal experts collaborating closely to reimagine corporate legal services from the ground up. We build proprietary technology and human-in-the-loop workflows to enhance the lawyer-machine relationship radically. We want to review complex documents, for example, faster than ever, and with perfect quality.

Crosby was founded by Ryan (Penn, Stanford Law, ex-Cooley, former GC) and John (Penn M&T, ex-Ramp, ex-Google).

We believe:

• A great legal system is the watermark of a great society.

• Legal work is an art and science. We want to discover the frontier between the two and codify the scientific parts, which is a magnificent puzzle.
