About Me

I’m Justin Sha, a California lawyer, founder, and adjunct professor based in San Francisco.

Sha.Law is where I write about law, business, and technology: which rules matter, how businesses operate, and the tradeoffs behind real decisions.

Lawyers tend to write like only other lawyers are reading. I try to write for the people making decisions.
