What Greyrock Capital Group buys
Greyrock Capital Group is a financing partner, not a lead buyer. It usually backs a sponsor with debt and equity rather than buying a company itself. For traditional private equity firms it supplies mezzanine debt with an equity co-investment. For independent sponsors, which raise money deal by deal, it offers one-stop junior capital, meaning a single check covering debt and equity. It has done 41 platform deals with independent sponsors since 2002.
It looks at companies with $2 million to $30 million of EBITDA and writes total checks from $8 million to $40 million or more. It wants stable results, recurring demand and a defensible niche in specialty materials and chemicals, education, distribution, manufacturing, aerospace, healthcare services, medical devices, business services, or food and beverage. Its $284 million Fund VI is the current fund, and it uses no fund leverage. Founded in 2001, it has offices in Walnut Creek, Chicago and Wilton, Connecticut. An owner will usually meet Greyrock through the sponsor buying the company, not as the direct buyer.

Greymont’s take
How Greyrock Capital Group fits a seller
Greyrock's site speaks to sponsors, not owners, so an owner rarely deals with it directly. If you sell to a private equity firm or an independent sponsor, Greyrock may be one of the investors behind that buyer. That can help, because one party covering debt and equity makes it more likely a smaller sponsor can close.
Greyrock also tends to stay with companies it knows. It reinvested from a newer fund when Ogle School Management, Precision Products Group and GED Integrated Solutions changed hands, and it says the same deal lead stays on through the investment. If you are rolling equity into the buyer's company, ask your buyer how much junior debt sits ahead of your shares, what the interest costs, and what Greyrock's equity and board rights are.
Questions owners ask
Does Greyrock Capital Group buy companies itself?
Usually not. Its recent news shows it financing other firms' purchases, such as CenterGate Capital's Spartaco Tool Group deal and Avista Healthcare Partners' Bentec Medical deal, rather than leading a buyout on its own.
Does Greyrock take equity as well as lending?
Yes. Its news page describes subordinated debt and equity in both Bentec Medical and Spartaco Tool Group in 2026, and it says equity co-investments are part of how it aligns with sponsors.
What size company does Greyrock look for?
Its criteria list $2 million to $30 million of EBITDA and total checks of $8 million to $40 million or more. It does not publish a revenue range.
Does Greyrock work with independent sponsors?
Yes, and it says this is a long-running focus. Since its first fund in 2002 it reports 41 platform deals with independent sponsors and more than $550 million invested with them.
