About MSG
Midstone Service Group is a long-term owner of Midwest-based industrial service businesses.
We partner with local companies where we see opportunities for steady, durable growth.
How are we different? We are not a traditional private equity firm. We are not looking to buy businesses, cut costs, and sell them in five years. We plan to own and operate our companies for decades—supporting local teams, serving local customers, and building businesses meant to last.
Mission & Vision
Driving Innovation Forward
Midstone Service Group began with a simple realization: facilities are put at risk for preventable reasons—missed inspections, expired certifications, inconsistent testing, or poor documentation. No one is solving this at scale. Our job is to ensure operators, engineers, and technicians never lose time, safety, or confidence due to failures that should never happen.
Midstone is building something new: a category-defining national platform for testing, inspection, and certification services that allows regulated facilities to operate without interruption. Our standard is built on accuracy, reliability, speed, and trust. That means:
-
One trusted partner and one consistent standard instead of fragmented vendors with different processes and expectations.
-
Service delivered exactly when it’s needed, done right the first time, with no rework, no surprises, and complete audit readiness.
