How to Build a Claude- Native Law Firm

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 discuss how to build an AI-native law practice and why pre-packaged legal tech wrappers can actually get between lawyers and the models. Zack breaks down the anatomy of 2,000-word prompts, the parallel between delegating to junior associates and directing AI, how to develop custom procedural skills, and how to eliminate hallucinations with multi-model verification. --- Timestamps: 00:00 – Introduction: Zach Shapiro & Rained LLP 00:44 – The Origin of the AI-Native Law Firm 03:32 – Scaling Lean: Competing with Big Law 04:38 – The Non-Technical Advantage 05:36 – The Newsletter 06:08 – The Mechanics of Prompting 08:24 – Why Lawyers Already Know How to Prompt 09:50 – Prompting vs. Custom Skills 12:46 – The Case Against Legal AI Wrappers 13:37 – Tackling Hard Cognitive Work 15:29 – Preventing Hallucinations & Auditing 16:19 – The Mindset Shift for the Future --- Each week I take what I'm hearing in conversations with legal leaders.
