Large law firms typically operate on a structure known as a pyramid or leverage model. The basic idea is that at the top there is a small group of equity partners who are expected to make it rain and bring in big clients, but who don’t actually do most of the work.
Beneath them is a middle layer of senior people who manage the day-to-day, and at the very bottom is an army of juniors who do most of the actual grunt work.
Because the base is wide and the juniors are getting billed at hourly rates that far exceed their fixed salaries, the partners at the top get the benefit of the excess funds flowing upward. It is a model that relies on juniors working long hours, most people burning out and leaving, and a relative few becoming partners.
But as we know, AI disrupts everything. Interestingly enough, Wall Street firms are reportedly going to their big law firms and saying, “Hey, now that AI is empowering you to work fewer hours and be way more efficient, we’d like you to tell us exactly how many hours you’re saving and reduce your fees accordingly.”
According to this recent FT article, the broad expectation is that the cost per transaction is going to come down significantly and that legal firms will need to adopt different business models in the short term.
I don’t think this necessarily means that legal firms will become less profitable, but it certainly encourages people to move away from “this is how many hours I worked” to “this is all the value that I created for you.”
