AI is fundamentally reshaping legal services — what legal work is, how it is delivered, and who is best placed to deliver it. This book examines how clients will drive disruption, what it means for law firms, and the strategies needed to thrive in an AI-powered legal industry.
Order Now"In this important book, Bjarne Tellmann reminds lawyers that the corporate legal services market follows developments in the corporate world not the other way around. In straightforward prose, Tellmann demonstrates that as companies transform to AI Factories, legal departments – and eventually, even traditional law firms – will have to follow suit. It should be required reading for both consumers and producers of legal services."

"The question on everyone's lips is whether we will finally see a disruption to a business model that has stubbornly resisted change for close to a century. Bjarne makes a compelling case that it will - and shows how legal service providers can pivot to outcome-based models and thrive in the AI era. Essential reading for anyone determined to stay relevant."
