Why Most $1M+ Businesses Fail When They Try to Scale
13/05/2026 | 44 mins.
#903 Most founders think revenue equals readiness — but scaling too early is one of the fastest ways to kill a business. In this episode, host Brien Gearin sits down with Mark Roberge — fourth employee at HubSpot, Harvard Business School professor, and investor in 200+ companies — to break down exactly when and how to scale revenue. Mark explains why product-market fit has nothing to do with sales numbers and everything to do with retention, how to identify your business's "leading indicator of retention" so you're not waiting a year to learn if customers are sticking around, and why go-to-market fit must come before you hire a single salesperson. He also unpacks the concept of "blitzscale pressure" and how it should shape the pace of your growth, plus shares his take on the four phases of how AI will reshape sales teams entirely!
What we discuss with Mark:
+ Revenue ≠ product-market fit
+ Retention is the real proof of value
+ Leading indicators of retention (P, E, T framework)
+ Product-market fit before go-to-market fit
+ Don't scale before you can serve profitably
+ Hire reps gradually, not all at once
+ Listen to business signals as you scale
+ Assess your category's "blitzscale pressure"
+ AI will take selling time from 25% to 75%
+ Build an advisory board early
Thank you, Mark!

11/05/2026 | 29 mins.
#901 What happens after you build something that actually works — and how do you keep growing when you're the one everyone looks to for answers? In Part 2 of this two-part episode, Tara Williams continues her conversation with relationship expert Stacey Martino, diving into the behind-the-scenes reality of running a business alongside your spouse, the personal work that never really stops, and why Stacey believes the "ascension spiral" is the key to navigating every new challenge life throws at you.

Whether you're working through a relationship, building a business, or just trying to figure out your next right step, this conversation will remind you that the hero's journey doesn't end — and that's actually a good thing!
