#357 Mary Shea: From Oboe Solos to Sales Strategy—A Career Reinvented — Part Two

Is two better than one?

In Part Two of this series, Mary Shea—former co-CEO of Mediafly and former General Manager at Hire Quotient—shares how she navigated one of the most unconventional leadership models in business: co-CEOship. From building trust with her co-leader to balancing responsibilities across time zones and product lines, Mary unpacks the human side of shared power—and why mutual respect beats ego every time.

She also explores how AI is transforming sales effectiveness, not just efficiency, and why today’s revenue teams need to look more like collaborative ecosystems than traditional hierarchies. Plus: what every leader can learn from marriage, tennis, and the occasional business referee.

Key Highlights of Our Interview:

AI for Sales: More Than Speed, It’s Strategy

“We’re not replacing reps—we’re freeing them up for high-impact work. That’s the real ROI of AI.”

The Death of the 80/20 Rule?

“With smarter tools, smaller teams can do more. We’re heading toward 80% of sellers driving 100% of revenue.”

AI as a Coach, Not a Crutch

“Think of AI as a coach on your shoulder. Helpful, but never a substitute for personalization or judgment.”

Behind the Scenes of Co-CEO Life

“It works because we trust each other. We split duties, share a vision, and treat decisions like a dialogue—not a turf war.”

The Marriage Metaphor (Yes, It Fits)

“Being a co-CEO is like a professional marriage. You need communication, shared values—and sometimes an executive coach.”

Slower Decisions, Stronger Outcomes

“We may debate more than solo CEOs. But those debates lead to smarter, more resilient choices.”

When the Umpire Steps In

“If we hit an impasse, we turn to our board and investors. Every partnership needs a higher court.”

Scaling Without Silos

“We empower leaders as mini-CEOs—but only if we keep the org aligned. Otherwise, remote work just breeds islands.”

The Bigger Game: Building Equity Through Leadership

“AI, revenue, strategy—it all comes back to who gets to lead. And how we help more people rise.”
