How to build a private equity buyer list that survives contact

A buyer list is the part of a process that gets the least attention and does the most damage when it is wrong. The materials can be excellent and the timing right, and none of it survives a list assembled from memory, last year’s tombstones, and whichever names the team happens to like.

What follows is the method, in the order the filters should be applied. The order matters, because each filter is cheaper than the one after it.

1. Fix the mandate before you look at any names

Write down four things about the asset and do not proceed until they are unambiguous.

Enterprise value, or a defensible range. This is the filter that removes the most names for the least effort, and it is the one people skip because it feels premature. It is not premature. A fund with a stated equity cheque of £50m upwards is not a buyer of a £20m business, and no amount of sector fit changes that.

What is actually being sold. A control stake, a minority, a carve-out, a recapitalisation with the founder rolling over. Each one addresses a different category of buyer, and a carve-out in particular has its own specialists.

The cash flow story. Whether the business is profitable, whether it is predictable, and whether it can carry debt. This determines whether a leveraged buyer can underwrite it at all.

The genuinely hard constraint. Regulatory approval, a customer concentration, a jurisdiction some funds cannot invest in, a founder who will not sell to a competitor. Better to know now than after four meetings.

2. Filter on size first

Take every candidate firm and ask one question: does the cheque this deal needs fall inside the range the firm publishes for itself?

Use the firm’s stated range, not an inference from its last three deals. Deals get announced selectively and a firm that did one unusually small transaction has not moved its mandate. Where a firm publishes no range, it belongs in a separate bucket for later research rather than in the list on optimistic grounds.

This step routinely removes half the candidates, and it removes them on a hard constraint rather than a judgement call. That is precisely why it goes first.

3. Filter on strategy, not on the firm’s name

A firm is not one thing. A large manager may run buyout, growth and credit out of separate funds with separate teams, and only one of them is a buyer of your asset. Target the strategy and, where you can, the fund.

The categories are not interchangeable, and the differences are structural rather than presentational — a credit fund does not buy equity, a venture manager cannot underwrite a profitable industrial business, and a secondaries fund does not buy operating companies at all.

4. Filter on geography as the firm defines it

Two fields, never one: where the firm is based, and where it says it invests. A London firm investing across the Nordics belongs on a Nordic list, and a list built on headquarters address will miss it entirely. Where a firm publishes a geographic remit, use that. Where it does not, its office footprint is a reasonable proxy and should be recorded as a proxy.

5. Filter on sector last, and hold it loosely

Sector is the filter everyone reaches for first and it deserves to be last, because it is the softest. Firms describe sectors broadly on purpose, definitions overlap, and a thesis-driven fund will happily look outside its stated sectors for the right asset. Applied early, it removes names that would have engaged. Applied last, to a list already constrained by size, strategy and geography, it is a sensible way to order the outreach.

6. Add the names that databases systematically miss

Two groups are usually absent and are usually worth having.

Independent sponsors, who raise equity deal by deal and therefore have no fund to be indexed against. They are real buyers, they are often quicker to engage than a fund with a committee, and they are invisible to any database organised around fund vehicles.

Family offices and family holding companies that buy directly. A different animal with a different timetable and, frequently, no exit horizon at all — which for some sellers is the whole point. They warrant their own list rather than a footnote on this one.

7. Record why each name is on the list

For every firm, keep one line: the constraint it satisfies, and where that came from. “Stated equity cheque £20–60m, buyout, UK and Ireland, business services — from the firm’s own strategy page.” It takes seconds and it does three things. It survives a challenge from the client. It survives the person who built the list going on holiday. And it makes the list re-runnable for the next mandate instead of disposable.

What to expect from the list

A longlist should be long enough to absorb attrition and short enough that every name can be defended. For a mid-market process, a few hundred names narrowing to a few dozen approaches is normal. Most of the drop-off happens at the size filter, which is why doing it first saves the most work.

The test of a good list is not its length. It is whether you can explain, for any name on it, why that firm could transact — and for any name that was excluded, why it could not.

Frequently asked questions

How long should a private equity buyer longlist be?

Long enough to survive attrition and short enough that each name can be justified. For a mid-market sell-side process, a longlist in the low hundreds that narrows to a few dozen genuine approaches is normal. A list of a thousand names is not a longlist, it is an unfiltered export.

Should sponsors and strategic buyers be on the same list?

Keep them separate. They are underwritten differently, they need different materials, and they run on different timetables. Mixing them produces a list that is optimised for neither.

What is the most common mistake?

Filtering on sector before filtering on size. Sector fit is easy to argue after the fact and easy to stretch; size fit is a hard constraint set by the fund's own mandate, and a firm that cannot write the cheque is not a buyer regardless of how well the sector reads.
