Just in the past month, the legal tech industry has seen a whirl of large investment rounds, product launches, and announcements of increased quarterly revenue, signaling, if nothing else, an active market that’s rapidly expanding.

The market also already has a few companies that have reached unicorn status—those with a valuation of at least $1 billion—including, Clio, LegalZoom and Relativity. Some believe that more companies will soon join them.
