30 Years of Industrial Leadership. Now Available on a Fractional Basis.
DEV Consultants was founded to bring senior operational and commercial leadership to founder-led and privately held industrial businesses on a fractional basis — delivering the impact of a full-time C-suite executive at a fraction of the cost and commitment.
What sets DEV Consultants apart is firsthand experience running companies of every type and size. Jeffery De Vaul has led small founder-run businesses, mid-market family-owned companies, and large investor-backed and multinational organizations operating within complex global matrix structures. He understands the daily realities each of these environments presents — the constraints, the politics, the decision-making dynamics, and the gap between what a business needs and what it can realistically execute. That experience translates directly into practical, implementable solutions rather than theoretical frameworks that look good on paper but stall in the field.
We focus on industrial manufacturers, distributors, and service companies providing machinery, mechanical equipment, and engineered solutions to Oil and Gas, Petrochemical, Power Generation, Transportation, Refining, Pharmaceutical, Municipal, Pulp and Paper, Food and Beverage, Aerospace, Automotive, Healthcare, and large Residential and Commercial facilities.
