Broken Searches: What Acquisition Rates Leave Out

By , Co-Founder and CTO, SMB Investor Network

Broken searches are funded searches that end without buying a business. An acquisition rate describes how often a defined group reached a purchase, but it cannot tell an investor whether that purchase ultimately made money. Understanding the risk starts with separating the search outcome, the population being counted and the investment outcome.

What a broken search means

A search can receive funding and still end without an acquisition. For someone funding that search, finding a business remains an unresolved task. The decision to provide search capital therefore comes before the investor knows which business, if any, will be acquired.

The phrase broken search describes the endpoint of that effort here: the search concluded without a purchase. It does not mean every abandoned acquisition discussion ended the search. A possible transaction and the overall search are different subjects, and a source needs to make clear which it is counting.

Jason Ehrlich draws the relevant distinction in Self Funded Search on The SMB Investor podcast. In paraphrase, funding the effort to find a business exposes an investor to a different stage of uncertainty from considering an investment after a target has been found.

That distinction helps identify what an investor is being asked to evaluate. Before a target exists, the business itself is unknown. After a target has been found, there is a business to consider, although identifying it does not establish that a purchase will happen or that the investment will succeed.

This is a distinction about entry timing. It does not establish that a particular investment model is safer overall. Moving the investment decision later changes the question in front of the investor; it does not answer every question that follows.

Readers who need the model definition can start with the search fund glossary entry. For the difference in roles and selection timing, the search fund and independent sponsor comparison provides a separate reading path.

Keeping the definition narrow also prevents a common reading error. A study of businesses that were acquired may offer useful information about ownership outcomes. Unless its scope says otherwise, it cannot describe the experience of searches that never reached ownership. Those missing searches matter to a reader whose starting point is funding the search itself.

Which searches enter the denominator

The denominator is the group against which an outcome is measured. In an acquisition rate, the numerator counts searches that acquired a company. The denominator determines which searches were eligible to be counted in the first place. A percentage loses much of its meaning when that group disappears from the sentence.

The Stanford GSB Search Fund Study reports that 58 percent of concluded core search funds in its US and Canada dataset acquired a company1. Among core search funds launched in 2021 to 2024 whose searches had concluded, about 48 percent acquired a company1. Both rates exclude active searches. These asset-class observations concern core search funds in the study's US and Canada dataset, not every search model or geography, and are not SMB Investor Network results.

Many searches end without an acquisition

Study acquisition rates: all concluded funds, 1984 onward, 58%; funds launched 2021–2024, about 48%. Filled bars show acquisitions and outlined remainders show no acquisition reported; the recap does not resolve active-search status in the recent cohort.

All concluded funds, 1984 onward: 58% acquired

Funds launched 2021–2024: about 48% acquired

Filled: acquired a company. Outlined: no acquisition reported. The recent cohort’s active-search status is not resolved in the recap; its remainder is not necessarily concluded broken searches.

The study reports acquisition rates of 58% for all concluded funds and about 48% for funds launched in 2021–2024, with different population definitions.

Figure note: Both rows count acquisitions among concluded searches. Active searches are excluded. The Stanford study says the earlier recent launch cohort was nearly fully concluded, while most searches in the latest cohort remained active at its observation cutoff.

The overall population includes searches that reached an outcome across launch years. The recent group selects funds by launch period and then counts only searches that had concluded. A cohort means a group selected by a shared characteristic, in this case its launch period. The recent cohorts have had less time to reach an outcome.

The comparison therefore needs more than a glance at the percentages. The study excludes searches that remain active from the acquisition-rate denominator and states how far the recent launch cohorts have progressed. The latest cohort is still substantially incomplete, so its rate describes concluded searches to date, not the eventual outcome of every fund launched then.

When the source describes this groupRead the result this wayKeep this qualification
It counts concluded searches.Both rates concern searches that ended in an acquisition or fund closure.Active searches are excluded from both denominators.
It groups funds by launch period.The recent rate concerns concluded searches from funds launched in that period.The earlier recent cohort was nearly fully concluded; most of the latest cohort remained active.
It counts acquired businesses.The result begins after an acquisition occurred.A purchase does not establish an investment gain.
It summarizes another publication.The recap is an intermediary for the reported rates.The underlying study confirms the concluded-search definitions and analyzes the cohort decline.

The study analyzes acquisition rates across concluded launch cohorts and finds a decline from earlier cohorts. The broad historical rate and recent combined rate alone do not show the full pattern; the study's cohort-by-cohort analysis does. The most recent cohorts are still incomplete, especially the latest one, so their rates may change as active searches conclude.

Avoid turning the gap into a new statistic. Subtracting the reported acquisition rates would not explain the study's finding about conditions and searcher preparedness. Nor would it reveal the share of investors who lost money. The useful reading note preserves each cohort's conclusion status beside its rate.

Why acquisition and investment loss differ

An acquisition answers whether a search reached a purchase. Investment loss concerns what happened to invested capital. The Stanford GSB Search Fund Primer separately observes that some searches fail to acquire a company and some acquired businesses lose money for investors2. The observations concern distinct outcomes.

A completed purchase cannot serve as proof of a successful investment. Equally, an acquisition-rate headline does not describe the size or timing of an investor's loss when a search ends without buying. Those questions require evidence about investor outcomes, beyond a count of searches that acquired a business.

Keep the primer's observation separate from the recap's acquisition rates. The primer supports the qualitative distinction between failing to acquire and losing money after an acquisition. It does not give permission to treat its population as the same population used in the recap or to combine the statements into a total loss rate.

This separation matters when reading the word success. A source may use it to mean a completed acquisition. A reader may understand it to mean an investment that made money. Both meanings concern an outcome, but they answer different questions. Before accepting a success claim, identify the event the author actually measured.

The same care applies when reading about returns from acquired businesses. Start by checking whether searches without acquisitions are included. Then ask what the reported measure says about the range of outcomes within its stated population. These questions should remain visible even when a summary offers an appealing headline.

The search fund return dispersion article extends that reading task by examining how outcomes can differ within a research population. This article addresses the earlier boundary: which searches reached an acquisition and which observations a purchase-based analysis may leave outside its scope.

The practical result is a more precise research note. Record acquisition as an event and investment gain or loss as a separate outcome. If the source reports only the event, leave the investment outcome unresolved. Uncertainty belongs in the note when the evidence does not answer the question.

Search duration and broken searches

Elapsed search time can sound like a verdict before the reader knows what it describes. A short search does not establish that the eventual investment will succeed. A longer search does not, by itself, establish that the effort has ended without a purchase. Duration and outcome need separate labels.

Contributor Sean Smith makes the narrower observation that search duration needs context in The Value of Industry Experience in ETA on The SMB Investor podcast. The useful point for research readers is that elapsed time needs an explanation before it becomes evidence for a conclusion.

Apply that point to the language of a study. Time since launch describes how long an effort has been observed. A concluded search describes its classified status. If a summary moves between those ideas, check whether it tells you enough to make that move. An unresolved status should remain unresolved in your own account.

This does not require choosing a preferred search duration. It requires resisting a judgment that the available observation cannot support. When a source gives a duration without the surrounding context, record the limitation instead of supplying an explanation yourself.

The podcast observation and the research definitions serve different purposes. Smith's comment explains why elapsed time deserves context. It does not define how the study classified its searches, explain the reported rates or supply evidence of a change across cohorts. Keep practitioner commentary beside the research as commentary, with its attribution intact.

Questions to carry into further reading

Use these questions when a research summary presents an acquisition rate or a search success claim. They help preserve the meaning of the evidence as it moves from a study into a recap and then into your own notes.

  • Does the author mean an ended search, an abandoned transaction or an acquired business?
  • Is the population selected by conclusion status, launch period or acquisition status?
  • Does the source explain how it handles searches still underway?
  • Is the reported outcome a purchase, an investment gain or an investment loss?
  • Can the claim be traced to underlying research, or does the available support stop at a secondary recap?
  • Does a comparison preserve population definitions and observation periods?
  • Is commentary about elapsed search time being used to imply an outcome that has not been established?
