Instead of selling software to traditional industries, a more defensible approach is to build vertically integrated companies. This involves acquiring or starting a business in a non-sexy industry (e.g., a law firm, hospital) and rebuilding its entire operational stack with AI at its core, something a pure software vendor cannot do.

Customers are hesitant to trust a black-box AI with critical operations. The winning business model is to sell a complete outcome or service, using AI internally for a massive efficiency advantage while keeping humans in the loop for quality and trust.

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.

Harvey's initial product was a tool for individual lawyers. The company found greater value by shifting focus to the productivity of entire legal teams and firms, tackling enterprise-level challenges like workflow orchestration, governance, and secure collaboration, which go far beyond simple model intelligence.

To penetrate tech-resistant markets like personal injury law, the winning model is not selling AI software but offering an AI-powered service. Finch acts as an outsourced, AI-augmented paralegal team, an easier value proposition for firms to adopt than training existing staff on new, complex tools.

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.

The transition from AI as a productivity tool (co-pilot) to an autonomous agent integrated into team workflows represents a quantum leap in value creation. This shift from efficiency enhancement to completing material tasks independently is where massive revenue opportunities lie.

Thrive Capital invested in an AI-powered accounting firm, not an accounting AI software tool. Their thesis is that in some industries, the service provider who uses AI to become hyper-efficient will capture more value than software vendors selling tools to a fragmented customer base. This is a bet on the business model, not just the technology.

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.
