“There's no vague advice here. Loop offers a coherent philosophy for how modern marketing actually works. That's especially valuable as the world keeps pace with AI. It’s required reading for teams serious about growth.”

—Alex Lieberman, Cofounder of Morning Brew and Tenex

“Distribution is becoming the new moat in the AI era, and this book will help you build that moat.”

—Lenny Rachitsky, Host of Lenny's Podcast

“Most people market. A select few build systems that create lasting impact. Kipp and Kieran have spent their careers understanding what separates the two. Loop is the distillation of those lessons—hard-won insights from years spent building, testing, and scaling what works.”

—David Senra, Host of Founders Podcast

“Loop spells out the next era of marketing instead of declaring the last one over. I helped build the last one—and I'm happily endorsing the new one. That's how good it is. AI didn't shrink the marketer’s role . . . it expanded it.”

—Dharmesh Shah, Cofounder and CTO, HubSpot

“I pay attention to people who built the thing they’re teaching. Loop was written by two people who built one of the biggest marketing engines on the planet, and it’s them showing their work. Read it and steal their homework.”

—Codie Sanchez, CEO, Contrarian Thinking

“Loop captures the shift every marketing leader needs to understand: AI is not just changing how we create and ship, it’s changing how buyers discover, evaluate, and decide. Kipp and Kieran give marketers a clear system for adapting to that new reality.”

—Elena Verna, Head of Growth, Lovable

“I've coached hundreds of CEOs and one pattern is clear: The best ones treat marketing like a growth system, not as a department. In Loop, Kipp and Kieran reveal the exact system leaders need to turn marketing into a compounding engine for growth—practical and essential for CEOs who want to scale.”

—Eric Partaker, CEO Coach, ericpartaker.com

“AI will make it easier than ever to create forgettable marketing. Loop is for the marketers who want to build something indispensable, more useful, and more human.”

—Joe Pulizzi, Founder of Content Marketing Institute and Author of Content Inc. and Epic Content Marketing

“Loop is the playbook modern marketing has been missing. It treats marketing as a system to engineer, and it gives you a proven framework to build that system inside your own team. A must-read for any leader who wants to get ahead in the age of AI.”

—Ben Meer, Speaker, Coach, and Author of How to Be Good at Life 

“Reading Loop is like having a great chef hand you their personal recipe book. The techniques are world-class, but the instructions are so clear you can actually pull it off in your own kitchen.”

—Jade Bonacolta, Founder of The Quiet Rich
