Key Takeaways

  • Consulting builds a general manager's toolkit: Paul Callahan, after years at Gartner and Bain & Company, saw his consulting experience as direct preparation for buying a 7-figure metal fabrication business, Metro Metalworks. He calls it building a “great general manager skill set and toolkit.”
  • Exposure to "good, bad, and ugly" accelerates insight: Callahan’s career exposed him to diverse business environments, allowing him to quickly spot pitfalls and bring fresh thinking to a manufacturing operation. He avoids “rabbit holes” others might fall into.
  • COVID-19 and family drive the pivot: At 49, Callahan left consulting due to the impersonal nature of remote work during COVID-19, intense travel, and a strong desire for more flexibility to be present for his teenagers and six-year-old.
  • Flexibility, not less work, is the prize: He admits entrepreneurship through acquisition won't mean fewer hours, but the greater control over his schedule was a core motivator for leaving a high-status career.

The Unconventional ETA Play: Consulting's Secret Weapon

Many founders assume the path to entrepreneurship through acquisition (ETA) runs through industry-specific experience or perhaps a scrappy startup background. Paul Callahan proves them wrong. After a successful management consulting career at top firms like Gartner and Bain & Company, Callahan, at 49, decided to buy his own business: Metro Metalworks, a 7-figure metal fabrication operation. His pivot wasn't a rejection of his past, but a surprising application of it.

Callahan pointed to the demanding travel and the shift to remote work during COVID-19 as key triggers for his career change. “COVID really made me take a step back,” Callahan said, noting the grating experience of “enough Teams calls, WebEx, and Zoom calls.” He also wanted to be more involved in his children's lives. “I've got a couple of teenagers now I've also got one six-year-old and you want to be a you know part of their lives in a way that you haven't been able to for many years.” The goal was not easier work or fewer hours, but genuine flexibility.

What makes Callahan's story sharp is his re-framing of a consultant’s typical journey. Instead of seeing his years at Gartner and Bain as a gilded cage or merely a corporate stepping stone, he viewed it as an intensive training program for business ownership. The core insight: high-end consulting, for all its perceived drawbacks, builds an uncommonly potent general manager skill set. It's not just about giving advice; it’s about rapid problem-solving across diverse operational landscapes, an ideal foundation for a future acquirer.

Why Your Consulting Stint is Better Than You Think

Callahan argues that working at a top consulting firm naturally grooms individuals for the challenges of buying and running a business. “The worst thing that can happen if you have a couple of decent years in a good consulting firm is you're going to build a great general manager skill set and toolkit,” he said. This isn't just about abstract strategic thinking; it is about developing a practical "muscle memory."

His consulting background gave him a unique vantage point, a kind of accelerated education in what works and what fails across industries. “I've seen what seen the good, bad, and ugly,” Callahan explained. This exposure helps him avoid common pitfalls and “rabbit holes” that might trap someone with deep but narrow industry experience. He can bring “new thinking” to a sector like manufacturing precisely because he hasn't been confined to it for 25 years. This ability to parachute into varied businesses, quickly diagnose issues, and apply cross-industry solutions is exactly what an ETA operator needs in the critical first year post-acquisition.

Your time in consulting, therefore, isn't just about client deliverables; it's a paid apprenticeship in operational mastery. Each project is a mini-due diligence, each recommendation a simulation of a strategic business decision. The exposure to different company cultures, financial structures, and market dynamics creates an adaptable, battle-tested generalist, perfectly primed to identify value and steer a new acquisition.
