How To Create a Claude- Native AI Law Firm with Zack Shapiro

In this episode, I'm talking with Zack Shapiro, founder of an AI-native law firm, Rains LLP. Zack is a corporate lawyer focused on startups and business law who has transformed his two-person practice into a high-leverage powerhouse serving over 200 clients. Despite describing himself as "uniquely bad at using tech tools," he has pioneered a "Claude-native" workflow that uses agentic AI to handle his legal work. We talk about the shift from "billable hours" to "high-judgment lawyering" and how prompting is becoming the most critical white-collar skill of the next decade. You’ll hear perspectives on why most legal tech "wrappers" are actually counterproductive that most lawyers are missing. The Power of "Bare Metal": Why Zack avoids expensive legal AI platforms in favor of direct, "bare metal" interaction with reasoning models like Claude. Prompting as an Essay: Moving beyond simple queries to 2,000-word "context dumps" that capture the nuance of a client's specific leverage and goals. Building Custom "Skills": How to use your own past work as a reinforcement learning environment to create agentic workflows that compound in value over time. The Entrepreneurial Opportunity: Why now is the greatest time in history for small, AI-empowered legal teams to steal market share from rigid, legacy firms. The Hallucination Filter: Practical strategies for using AI to check itself, ensuring that "turning your brain off" never becomes an option. -------- Each week I take what I'm hearing in conversations with legal leaders.
