A thesis that cannot rule a company out is not a thesis. Most of its working value sits in the disqualifiers, which is the part buyers most often leave unwritten.
Start a private conversation with the Acquisition Concierge, already scoped to the acquisition thesis. Pick a starting point, or describe your situation directly.
A written acquisition thesis does two jobs. It tells intermediaries, lenders and your own team what you are looking for in terms precise enough to act on, which is why buyers with a thesis get shown better opportunities than buyers who describe themselves as opportunistic. And it protects you from yourself, because the moment you meet an attractive company your criteria will begin to drift toward it, and a document written in advance is the only reliable check on that drift. The parts that do the most work are the least comfortable to write: the revenue and EBITDA range you will actually transact in, what happens to the seller after closing, the customer concentration you will tolerate, and the attributes that rule a company out no matter how good the price.
Vague on any one of these and the thesis stops filtering. The test throughout: could someone else use this to tell you no?
Revenue and EBITDA range, margin profile, capital intensity, the band you can actually finance and absorb, not the band you find interesting.
Adjacency to what you already do, and whether revenue is recurring, contracted or transactional.
Where you can realistically manage a business, including the travel and presence integration will demand.
The customer base you want and the concentration you will tolerate, stated as a number, before you meet a company that exceeds it.
Whether you need the owner to stay, for how long, and whether a management team exists beneath them.
The attributes that end the conversation regardless of price. The most valuable section and the most frequently omitted.
How the Institute helps an owner get a thesis onto paper.
The difference shows up in the quality of what you are shown, and in how quickly you can decline it.
They are easy to write while no company is in view and nearly impossible to write honestly once one is. Buyers who skip this step routinely rationalise past the exact issue that later defines the deal.
Narrow enough that a competent intermediary could screen for you without asking follow-up questions, and no narrower. Over-narrowing produces a search with no candidates; under-narrowing produces a stream of opportunities you evaluate one at a time on their own terms, which is expensive in attention and corrosive to discipline. A practical test is whether the thesis would let you decline an attractive company that does not fit, if it would not, it is a description rather than a filter.
It should include valuation parameters, the multiple range you consider defensible for this profile of business, and the leverage you are willing to carry. It should not include a target price, because price is a function of the specific company and what diligence reveals. The useful discipline is stating in advance what would justify paying above your normal range, so that when you do it is a decision you recognize rather than a drift you notice afterward.
Treat it as a decision that gets made explicitly and in daylight. Sometimes the company is genuinely revealing that the thesis was wrong, and the right response is to amend the document and say why. What causes harm is the unexamined version, where criteria quietly relax to accommodate the company and nobody notices the thesis no longer describes what you are doing. Writing down the amendment is a small ritual with a large effect.
Your leadership team, so the search is not carried in one person's head. Your lender or prospective lender, because a specific thesis makes financing conversations concrete rather than hypothetical. And any intermediary you engage, a banker or broker working from a precise thesis shows you materially better-fitting opportunities than one working from "profitable companies in our sector." A thesis you are unwilling to share tends not to be specific enough to be useful.
Describe what you are looking for. The Concierge will work through the dimensions with you, including the disqualifiers.
