A consulting partner for leaders who mean to win.
From our home at 30 Broad Street in New York's Financial District, we've spent six years helping organizations navigate complexity and capture opportunity — building a track record one engagement at a time.
Built on a simple belief
Great strategy is worthless without great execution. JMC was founded in 2020 to close that gap — to be the firm that stays in the room long after the presentation ends.
Today we advise mid-market and enterprise clients across North America, blending deep analytical rigor with a hands-on, operator's sensibility. We are small enough to care about every engagement and senior enough to deliver them.
Values that shape every engagement
Rigor
Every recommendation is grounded in evidence, not opinion.
Partnership
We measure success by your outcomes, not our billings.
Ingenuity
Fresh thinking for problems that refuse to fit a template.
Excellence
A relentless standard for the quality of the work we deliver.
Senior people, on every project
Our partners are not figureheads. They lead the work.
