What Argentum Capital Partners buys

Argentum Capital Partners is a New York growth equity firm founded in 1988. It mostly takes minority stakes, so the founder usually keeps control and keeps running the company. It backs bootstrapped, founder-owned or closely held business services and B2B technology-enabled companies with $10 million to $50 million of revenue that are profitable or close to it, and it typically invests $5 million to $20 million. Larger checks, majority stakes or buyouts are possible when a deal calls for them, but they are the exception. The money can fund growth, acquisitions or a partial payout to the owners.

Argentum says it has backed more than 100 companies and supported more than 200 add-on acquisitions, and it often sources those add-ons itself. Recent investments include Truck Parking Club, Overwatch Mission Critical, CloudCover, JessCo and Alarm Masters. A smaller company is most likely to meet Argentum as an add-on to one of these. Alarm Masters, for instance, was built to buy independent fire alarm and security firms.

Greymont’s take

How Argentum Capital Partners fits a seller

Argentum is not a full-exit buyer. It suits a founder who wants to take some money off the table or fund growth and acquisitions while keeping majority ownership and the day-to-day job. CloudCover's founder stayed chairman and CEO and remained the majority shareholder after the 2025 deal, and JessCo's three co-founders kept significant stakes. An owner who wants to sell all or most of the company should talk to control buyers first.

Its partners usually join the board and stay active in finding add-ons and customers, so this is not a passive investor. Argentum also needs an exit in time: LAUNCH took a majority investment from Capitol Meridian Partners in February 2025, and the firm reports more than 80 exits. Ask when and how Argentum expects to sell its stake, what say a minority investor has over a future sale, and how much of the money goes to the owner rather than the company.

Questions owners ask

Does Argentum buy control of companies?

Usually not. It says it primarily invests $5 million to $20 million for minority stakes so founders keep majority ownership, though it can do a majority deal or buyout when one is needed.

What size company does Argentum invest in?

Its criteria call for $10 million to $50 million of annual revenue and a business that is profitable or close to it. A November 2026 release gave the lower end as $5 million, so the floor may be flexible.

Will Argentum help a company make acquisitions?

Yes, that is central to how it works. It says it has supported more than 200 add-on acquisitions, and leaders at Fleetworthy and LAUNCH credit it with finding acquisitions for them.

Does Argentum invest in IT services companies?

Yes. In July 2025 it made a growth investment in CloudCover, an Irvine, California provider of third-party IT hardware maintenance and lifecycle services sold through IT channel partners. The founder stayed on as CEO and majority owner.
