Harvey AI's co-founder predicts AI will allow law firms to break the traditional billable-hour model. This shift will enable them to operate at a much larger scale with software-like margins, fundamentally changing the industry's structure and creating massive winners.

Comparing legal AI firm Harvey's $8B valuation on ~$100M ARR to ServiceTitan's $9B on $866M revenue reveals a market shift. Investors are underwriting AI companies not on existing market size but on the belief they will enable widespread labor displacement, creating an entirely new, massive market.
VCs have traditionally ignored the massive $16T services sector due to its low margins. AI automation can fundamentally change this by eliminating repetitive tasks, allowing these companies to achieve margin profiles similar to software businesses, thus making the sector newly viable for venture investment.
Instead of selling AI co-pilots, legal tech startup Crosby operates as a full-stack law firm using AI internally. This model allows them to continuously re-orchestrate workflows between human lawyers and AI as models improve. This captures the entire value of automation rather than just the limited margin from selling a software tool to other firms.
The traditional law firm model relies on a large base of junior associates for grunt work. As AI automates these tasks, the need for a large entry-level class shrinks, while mid-career lawyers who can effectively leverage AI become more valuable, morphing the firm's structure into a diamond shape.
While law firms have an inherent conflict with AI due to the billable hour model, the push for adoption is coming from their clients. Corporations are now sending formal requests to their legal counsel, requiring them to use AI tools for efficiency and cost savings, thereby forcing the industry to adapt despite its traditional economic incentives.
VC Keith Rabois highlights a core conflict: law firms billing by the hour are disincentivized from adopting AI that makes associates more efficient, as it reduces revenue. This explains why corporate legal departments are faster adopters—their goal is to cut costs.
A new ecosystem is emerging where law firms are not just end-users of Harvey's AI but also channel partners. They are leveraging their expertise to help their in-house legal clients adopt and implement the technology, creating a new, high-margin line of business for themselves as tech consultants and implementers.
Within the last year, legal AI tools have evolved from unimpressive novelties to systems capable of performing tasks like due diligence—worth hundreds of thousands of dollars—in minutes. This dramatic capability leap signals that the legal industry's business model faces imminent disruption as clients demand the efficiency gains.
The most durable AI applications are those that directly amplify their customers' revenue streams rather than merely offering efficiency gains. For businesses with non-hourly billing models, like contingency-based law firms, AI that helps them win more cases is infinitely more valuable and defensible than AI that just saves time.
AI tools drastically reduce time for tasks traditionally billed by the hour. Clients, aware of these efficiencies, now demand law firms use AI and question hourly billing. This is forcing a non-optional industry shift towards alternative models like flat fees, driven by client pressure rather than firm strategy.
