LegalTech’s “Open Source” Moment!
With AI usage for legal approaching “near-universal” adoption, the sector continues to evolve at an astounding pace.

The article cited the announcement by Kirkland & Ellis, the largest law firm by gross revenue last year, that it plans to spend $500 million to develop its own AI apps, as well as Freshfields collaboration with Anthropic to develop a legal AI tool for its 4,000 attorneys, in exchange for early access to the company’s models.
