Welcome to Operating by John Brewton

The Newsletter That Turns Operating Complexity Into Competitive Advantage

Every week, 30,000+ operators, founders, and strategic professionals face the same challenge: How do you build companies that win in an AI-enabled, rapidly changing business environment?

Most get advice that’s either too theoretical (academic papers disconnected from reality) or too tactical (tips without strategic context). Operating by John Brewton bridges that gap.

What You’ll Get:

Each week, I synthesize insights from economic history, business strategy, and real-world operating experience to help you:

  • Navigate AI transformation with frameworks grounded in economic theory and proven practice

  • Optimize operations using lessons from companies that successfully scaled

  • Make better decisions by understanding the historical patterns that shape today’s business landscape

  • Build antifragile systems that gain from volatility rather than break under pressure


You’re an operator, founder, strategic professional or student who:

  • Leads teams through transformation and growth

  • Makes decisions that shape your company’s trajectory

  • Values deep analysis over superficial hot takes

  • Wants to understand why things work, not just what to do


I’m a Harvard-trained economist who spent two decades in the operating trenches.

  • Scaled a B2B industrial company from $27.5M to $75M (while reducing headcount 40%, managing the company to grow EBITDA, and ultimately achieve a successful exit).

  • Economics PhD candidate at the University of Chicago​

  • Now advise founders and operators through 6A East Partners​

  • Research and write about the future of companies daily​

  • Build an audience of +30,000 operators on LinkedIn

I started this newsletter because operating is hard. Very hard. The best operators combine historical understanding, economic frameworks, and practical execution.

But that knowledge is scattered. I synthesize it for you.​
