Frontenac
The Firm
Frontenac is one of Chicago's oldest private equity firms, founded in 1971, with thirteen funds, $3.8 billion committed, and 350 deals across its fifty-plus years. Since 2002 its identity has been CEO1ST: the firm selects an experienced operating executive first, builds an investment thesis with them, and then buys a company for them to run, pairing the operator with what it calls repeatable value-creation playbooks.
It targets growth buyouts of profitable, privately held lower-middle-market companies in consumer, industrial, and services, and specifically situations tangled in what it names complex transition issues, liquidity, management succession, growth planning, which is a precise description of the retiring-owner businesses a searcher hunts. Its Digs Dog Care platform bought seventeen pet resorts in its first year.
CEO1ST deserves a searcher's close attention because it is institutional search: an executive with a thesis, capital behind them, hunting owner-transition companies. The difference is the executive works for Frontenac's fund. Anyone interviewing there should know the 1971 founding, the CEO1ST mechanism and its 2002 launch, and the transition-issues language, because the whole firm is organized around that motion.

Confirmed Deals
1 deal traced to announcements by Frontenac, 2025, newest first. Firms that announce every deal show a fuller run here than firms that report acquisitions as quarterly counts, so read this as the evidence that clears the bar rather than as the firm's whole record.
Nothing newer has cleared the bar in 12 months, against a registry whose newest confirmed deal is August 6, 2026. A gap past 12 months can mean the firm has slowed, or that it has stopped announcing; treat it as a prompt to check its own newsroom before assuming either.
