O2 Investment Partners, a private equity firm in Bloomfield Hills, today announced it has partnered with 4M Building Solutions and its CEO, Tim Murch, to support the company’s rapid growth. Terms of the investment were not disclosed.

Headquartered in St. Louis, 4M is a premier full-service commercial cleaning, janitorial, and housekeeping services company with operations spanning 15 states across the Midwest, Northeast, and Southeast. The firm’s 4,000-plus employees clean 135 million square feet of space daily.

“We are thrilled to partner with O2 to further drive our strong growth trajectory, both organically and through acquisitions,” says Murch. “We truly believe we have only scratched the surface of our potential, and this investment will help us to cement our leading position in the janitorial services industry.”

4M will continue to operate independently under the leadership of Tim Murch and its current executive leadership team.

Sean Darin, a vice president at O2, says 4M has “an industry leading platform poised for organic and inorganic expansion. We believe there are significant tailwinds driving growth for janitorial and cleaning services, which we can capitalize on while continuing to maintain 4M’s reputation as the acquirer of choice within the industry.”

4M is the second platform investment for O2’s most recent fund, O2 Investment Partners Fund IV.

Founded in 1978, 4M Building Solutions cleans corporate owner-occupied facilities, multi-tenant office buildings along with industrial and manufacturing, logistics, distribution, health care, educational, and senior-living facilities. For more information, visit
