Purpose-Built AI vs. Generic Models

In this episode, Steve Fretzin and Mathew Kerbis discuss:

• AI’s impact on billable work
• Recognizing the limits of hourly and flat fees
• Using subscriptions to create stability and scale
• Positioning lawyers for long-term resilience

Key Takeaways:

• AI is set to automate most billable legal tasks, collapsing the hours firms rely on for revenue. Continuing to bill time while effort shrinks creates ethical and financial strain. The profession must rethink pricing before the model breaks entirely.
• Hourly billing punishes efficiency and leaves clients unable to budget. Flat fees help, but often trigger resistance when AI makes work appear “too easy.” Both models strain under faster, AI-driven workflows.
• Subscription pricing offers predictable costs for clients and recurring value for firms. Changing needs are handled through tier shifts instead of constant renegotiation. This approach opens access to the vast unmet legal market.
• Solo and small firms can thrive by pairing subscriptions with purpose-built AI tools. Clear value mapping enables strong good-better-best service tiers. Sustainable growth requires leverage, focus, and letting go of doing everything alone.

"The flat fee or fixed fee model… hasn’t supplanted the billable hour… because of exactly this problem I call the under‑scoping and over‑scoping problem. You don't know if you're going to overscope or underscope the work when it's on a fixed‑fee model." —  Mathew Kerbis
