The large majority of private companies are not for sale, which is exactly why they are worth approaching. It is also why most proprietary searches quietly stall.
Start a private conversation with the Acquisition Concierge, already scoped to proprietary search. Pick a starting point, or describe your situation directly.
A proprietary search inverts the usual sequence: instead of responding to companies that have decided to sell, you decide which companies you want and then find out whether their owners might ever be persuadable. Done well, it begins with a market map, a systematic enumeration of every company matching your thesis in a defined geography or sector, with enough detail to rank them, and proceeds through patient, individually considered outreach. Done badly, it is a mail-merge to a scraped list, which produces no meetings and burns a reputation in a market where owners talk to one another. The determining variable is almost never the list; it is whether anyone has the discipline to work it for a year.
The map is the easy part. The sustained, individualised follow-through is where searches succeed or quietly die.
Enumerating every company in the defined space, from association lists, trade directories, filings, industry press and your own knowledge.
Ranking the map by fit so that effort concentrates on the companies you would actually want.
Establishing who actually decides, founder, family, partners, a private equity sponsor, before the first approach.
Letters written to a specific company by someone who understands it. Volume approaches announce themselves and are ignored.
Most owners who eventually sell said no first. The searches that work are the ones still going in month eighteen.
Accountants, lawyers, lenders, trade associations and owner networks, frequently more productive per hour than cold outreach.
How the Institute helps with a proprietary search.
It is the cheapest route in fees and the most expensive in attention. Buyers consistently underestimate the second.
A proprietary deal removes competitive tension, which cuts both ways: you may pay less, or you may be the only party who has ever tested the seller's expectations. Nothing about proprietary sourcing substitutes for diligence.
Large enough to survive attrition, which is severe. For a specific thesis, a map of a few hundred companies typically screens down to fifty or so genuine fits, of which a minority respond, a minority of those meet, and a small number ever reach a serious conversation. Buyers who start with a list of twenty tend to run out of candidates and then relax their criteria, which is the mechanism by which a disciplined search becomes an opportunistic one without anyone deciding to change strategy.
Personally, specifically, and without any suggestion of a process. Owners who have not decided to sell are being asked to consider something significant and private, often for the first time, and the approach that works reads as a considered conversation between operators, evidence you understand what they built, a clear statement of who you are, and an explicit acknowledgement that you are not conducting a broad search. What fails is anything that reads as volume: generic praise, an unnamed sender, a valuation range, or urgency of any kind.
Owner-to-owner is generally more effective for a first approach, a founder who has built something responds differently to a peer than to an intermediary, and the signal that you cared enough to write yourself is part of the message. An advisor becomes useful for volume, for maintaining confidentiality about who is behind the approach, and for handling the follow-up cadence that owners running their own companies typically cannot sustain. Many buyers use both: personal letters to the priority tier, advisor-run outreach across the rest.
Record it, thank them, and plan to be in touch in a year. The single most reliable finding in proprietary search is that circumstances change, health, partners, a difficult year, an unsolicited approach from someone else, and the buyer who is remembered as courteous and unhurried is the one who gets the call. A no is close to meaningless as a permanent signal and quite valuable as the start of a relationship. Searches fail far more often from abandonment than from rejection.
Describe the market you would map and the time you could give it. The Concierge will orient you on what it would actually take.
