What OceanM19 buys

OceanM19 is the investment office of one family, based in Hinsdale, Illinois, outside Chicago. It invests the family's own money rather than a fund raised from outside investors, and it describes that money as patient. Direct private equity is one part of what it does: it also places money with hedge funds, venture capital and real estate, which this profile does not cover. For private equity it usually wants control of companies with $10 million to $100 million of revenue and $2 million to $10 million of EBITDA.

Its three target areas are niche manufacturing, business services and food and ingredients. It looks for companies with a spread of customers, steady repeat cash flow and real barriers to entry. Recent activity is a mix: it lists Utility Revenue Services as acquired in June 2025, and its 2024 investments in two metal fabricators and a helicopter maker were minority or growth stakes. Founders and managers can invest beside the family and keep day-to-day control. It doesn't always lead: eleven of its sixteen companies are also listed by other investors in this directory, so many of its holdings are stakes beside another buyer, and an owner should ask whether it would lead the deal.

Greymont’s take

How OceanM19 fits a seller

OceanM19 suits an owner who wants a long-term partner with no fund clock. Because the money belongs to one family, there is no set date by which the company must be sold again, and the firm says it can decide quickly and be flexible on structure. It also says owners and managers can keep running the business day to day and invest beside the family.

The team is small and it does few deals: its list shows one company acquired in 2025 and three minority or growth investments in 2024. So an owner should ask how much time the family's team can give the business after closing, and whether the family would be buying control on its own or investing beside another firm. Several of its past holdings were sold after three to five years, so it is also fair to ask how long it expects to stay.

Questions owners ask

What size of company does OceanM19 look for?

For private equity deals it says it usually seeks control of businesses with $10 million to $100 million of revenue and $2 million to $10 million of EBITDA.

Does OceanM19 always buy control?

No. It says it typically seeks control, but its own investment list labels EZ Fabricating (November 2024) and Washington Metal Fabricators (February 2024) as minority investments and Phenix Solutions (July 2024) as growth capital.

Which industries does OceanM19 focus on?

Three areas: niche manufacturing such as engineered parts and packaging materials, business services such as revenue cycle management, testing and outsourced facility services, and food and ingredients for retail and foodservice.
