Episode 191 - Colby Culbertson

Agent Series 21: He Quit Zillow to Build a Real Estate Empire

Start listening

Colby Culbertson didn’t just leave a cushy Zillow gig. He jumped back into production and built one of Northern California’s top real estate teams—scaling from 6 to 185 agents in just 5 years.

In this episode Colby unpacks the real story behind his 875-unit, $545M volume business. He shares why culture eats production for breakfast, and why his team runs more like a startup than a traditional brokerage.

You’ll learn:

  • Why he counter-recruits top agents (and what he tells them in the first 5 minutes)
  • The onboarding challenge every agent must complete before joining
  • His “no *expletive*” rule—and how it applies to $50M producers
  • How a shared tech stack keeps 180+ agents aligned
  • Why some agents are terrible negotiators (and how to fix it)
  • What Zillow got right—and where they still miss

Colby built a scalable, culture-driven business using systems, honesty, and a ruthless focus on the right people—not just more people.
