Start it. Build it. Make it last.
Expertrev is the consulting practice of John McGuire — a seasoned operator who helps founders and small businesses go from idea on paper to growth, diversification, and the strategic partnerships that unlock the next chapter.
Three decades. Real numbers.
The work speaks in outcomes — companies launched, capital raised, markets entered, and people served. A snapshot of what's been built across healthcare, technology, and consumer ventures.
A practice for every stage.
From Paper
Validating an idea, shaping a model, building the foundation a business actually needs to start.
From the Ground Up
Operations, hiring, systems and pricing — the unglamorous work that creates real leverage.
From Stuck to Growth
Diagnosing what's holding you back and engineering the next chapter of expansion.
From Local to Lasting
Diversification, strategic partnerships, and the long-term moves that make a company durable.
“Every business has a moment when the next move is unclear. My job is to make it obvious.”
Fifteen minutes.
No obligation.
Tell me where you are, where you'd like to be, and what's in the way. We'll see if there's a path forward worth walking together.
