What Post Capital Partners buys
Post Capital Partners is a New York private equity firm founded in 2004. It invests in lower middle market companies in the United States and Canada, typically with $10 million to $150 million of revenue and $2 million to $20 million of EBITDA, and it favors businesses with repeat or recurring revenue. It does management buyouts, recapitalizations, corporate carve-outs, majority buyouts and minority growth deals. In January 2025 it said it was investing from its fourth committed fund, backed by institutional and private investors; it does not publish fund sizes.
Its calling card is an executive-first approach. Post often teams up with an experienced operating executive first, sometimes hunting for a company around that person's plan, and gives senior managers real equity. Its current search list covers managed IT and cybersecurity, IT consulting, waste collection and disposal, commercial HVAC and mechanical work, commercial solar services, behavioral healthcare and marketing services. It owns four companies today, RKON, Ironmark, Agile Utility Partners and Newcourse Communications, and three of them bought add-ons in 2025.

Greymont’s take
How Post Capital Partners fits a seller
Post Capital suits an owner who wants to sell or step back and would like a proven executive to take the reins, or a management team that wants to buy out its owner. Because the firm often brings in an outside operating executive as its partner, owners should ask early whether that person would run the company after closing and what that means for the current leaders. Managers usually receive meaningful equity tied to results.
Right now the clearest add-on fits are managed IT and security firms, utility field service businesses and marketing services companies: RKON bought ScaleSec in November 2025, Agile bought Ground Hawk in September 2025, and Ironmark has made five add-ons since 2022. Owners of waste businesses should know Post is searching in that field again but sold its last waste platform, EC Waste, to 3i in 2021. Ask how long it plans to hold and how a later sale would work.
Questions owners ask
What size companies does Post Capital Partners invest in?
Its typical platform has $10 million to $150 million of revenue and $2 million to $20 million of EBITDA, is based in the United States or Canada, and earns repeat or recurring revenue.
What does Post Capital mean by executive-first?
It starts each deal by teaming up with a senior operating executive, either a management team already running a business or an outside leader with a plan to buy and grow a company in their industry. Those executives get equity in the companies they help lead.
Does Post Capital buy IT services or waste companies?
Yes. It owns RKON, a Chicago managed IT and cybersecurity provider that bought ScaleSec in November 2025, and its current search list names managed IT, cybersecurity and waste collection and disposal. It sold its earlier waste platform, EC Waste, to 3i in 2021.
Will Post Capital take a minority stake?
Yes. Its criteria say it will take either a minority or a majority position, and its minority growth capital can fund acquisitions, organic growth or a partial payout to owners.
