Locate the page on your site dedicated to showcasing wins. Most firms have one. Usually it’s a logo wall, or a list sitting under a heading like “Recent Successes,” with bullets that read something close to this:

• Placed a CTO at a Series B SaaS company. 
• Placed a CFO ahead of a funding round. 
• Placed a VP of Engineering in 62 days.

Every one of those is true, but none of them serves as proof.

That’s the contradiction most search firm marketing carries. Your whole pitch to a board is that your people assessments consistently outperform internal talent teams and boutique competitors. But what you publish to support the pitch is a record of outcomes, which is precisely what a firm with a worse process and better luck would publish.

And it isn’t a volume problem either. Content Marketing Institute and MarketingProfs (≈980 respondents) found that 75% of B2B marketers used case studies or customer stories last year. So the problem isn’t that your buyer is short of these narratives, it’s that they’re drowning in interchangeable ones.

Your logo wall is more a liability than an asset

Customers who can’t differentiate don’t stop deciding. They fall back on whatever criterion still distinguishes the options, and in professional services that’s price or brand recognition. 

For a retained practice that charges premium fees, those are the two worst grounds to compete on. The firms that win on them are the largest global brands and low-cost firms. You’re neither.

So a case study achieves more than typical formats do. It’s the one artifact where you get to show a buyer the reasoning behind the result, before you’re ever in the room to explain it. Choosing a logo for that slot wastes the chance to show your reasoning; it only signals that you’ve worked with someone before.

Outcome-only versions keep getting written

Three real constraints produce it, and none of them is laziness.

The first is confidentiality. AMost clients do not want a public story about approaching a competitor’s vice president, and a sensitive founder succession is worse. Outcomes are the part you’re actually cleared to publish.

The second is time. To extract technical details you must sit a consultant down and reconstruct an eight‑month‑old search. That’s an afternoon you don’t have to spare between two live commitments.

You’re confident about the third. The placement happened. You can verify it. The judgment behind it feels arguable, and putting arguable things in marketing copy takes nerve. 

I’d call all three rational. They’re also why the generic version keeps getting published, and why the firm that solves them gets a very quiet advantage.

The real measure of a placement result

Here’s the mechanism.

Any outcome fits equally well with almost any process that led to it. “We placed a CPO in 62 days” fits with a market map, a structured assessment, and eleven confidential conversations… or one lucky referral from a partner’s neighbor. The sentence doesn’t discriminate between those, which means it can’t move a buyer who’s trying to work out which one you are.

Think about two contractors bidding on the same renovation. Both recently completed a job; one brings photos of the finished kitchen, while the other describes finding rot behind the sink and how they handled it. Only one of those two has told you anything about what happens when your job goes sideways.

A board evaluating your firm is hiring the second contractor. They already assume you can fill a seat. What they’re trying to determine is how you make decisions in circumstances that are unpredictable. 

Which means the measurement unit of a case study is the decision, not the placement.

Vacancy cost over speed

Speed is the metric almost every search firm reaches for, and I understand the pull. It’s clean, it’s numeric, and clients complain about slow searches constantly.

But the research doesn’t back it up.

Chen and Li, published in Review of Accounting Studies in 2023, measured job vacancy duration directly from the creation and deletion dates of job postings by US public firms between 2007 and 2018, then tested it against’ those firms’ later profitability. Their findings differ by role level. Companies that filled low-skill roles quickly and those that delayed high-skill hires both saw higher future profitability. They conclude that profitable firms are selecting carefully where selection quality actually matters, and moving fast where the cost of the empty seat dominates.

Sit with that for a second, because it inverts the usual pitch. In the segment you work in, a quick fill doesn’t clearly indicate positive performance. To a sophisticated buyer, “62 days” may look like the company stopped searching prematurely.

I want to present this caveat bluntly and upfront. That study is about corporate job postings at large public companies, not about retained search engagements. In those job postings, vacancy duration doesn’t equate to your time-to-shortlist. 

Another important clarification: Chen and Li’s “high-skill” isn’t an executive designation, it’s any posting paying above the median for its industry and year, so their sample extends well beyond the C‑suite. The essential signal remains because the buyer’s influence operates the same regardless of seniority: speed and selectivity balance against each other in senior roles.

The practical version is simpler. Stop leading with the elapsed days. Speed only becomes an asset in your case study when you’ve first established what the empty seat was costing, which is a different number entirely, and a much better one.

Using the client’s own numbers

This is where the original argument for velocity should have been sitting all along.

SHRM’s 2025 benchmarking research, based on a survey of 2,371 members fielded between January and March 2025, found that executive hires cost nearly seven times more than non-executive hires. The follow-on data is more interesting for your purposes. In SHRM’s 2026 recruiting benchmarking, drawn from over 4,600 organizations, median time-to-fill for non-executive roles fell to 39 calendar days while time-to-fill for senior-level roles was unchanged, and executive cost-per-hire rose. 

Read that as a two-speed market. Average hiring became faster and cheaper, while senior-level roles saw no improvement. That gap is your entire commercial case, and it belongs in your case studies as the client’s problem rather than as your boast.

Clients consistently undervalue the impact on the team while a seat is vacant. In 2023, Pieper and colleagues used data from 239 general manager departures across units of a US retailer between 2012 and 2014. Writing in the Journal of Applied Psychology, they found that the turnover that follows a manager’s exit is delayed and uneven rather than immediate. The takeaway for companies is: the absence of resignations in month one produces a false sense that the unit had absorbed the shock.

That study tracked retail store general managers, not technology executives, but the lag they describe between a leadership exit and the resignations that follow doesn’t obviously depend on organizational level. So when a CTO seat sits open for five months and nobody quits, the board concludes the unit held. The resignations arrive in month seven, and by then they get attributed to compensation, or a manager, or the market.

If your case study is the document that connects those two events for a buyer, you’re no longer selling recruitment. You’re selling the thing they got wrong last time.

Name the client’s problem in numbers a CFO recognizes

The old advice was to open a case study with the client’s pain instead of the candidate’s resume, which is right as far as it goes. The trouble is that “they were drowning in technical debt” is a vague descriptor. Better to replace it with measurable language such as “X in annual maintenance costs” or “Y hours/week lost to legacy systems.” Converting the problem into numbers (e.g., $/month of wasted spend, % of revenue impacted, days of downtime per year) gives it a magnitude the buyer’s finance function will accept. 

McKinsey surveyed 50 CIOs at financial services and technology companies with revenues above $1 billion in July 2020. Those CIOs reported that 10-20% of the technology budget earmarked for new products was being diverted to tech debt, with the debt itself estimated at 20-40% of the value of their entire technology estate before depreciation. Because the sample is small, dated, and biased toward large enterprises, treat it as a reference point rather than a Series B benchmark.

Used properly, it sounds like this in a case study: “The client’s engineering organization was spending roughly a fifth of its new-product budget servicing decisions made three architectures ago, which is at the upper end of what McKinsey’s CIO survey found, and it was the reason the roadmap had slipped twice.”

Assigning a figure makes the executive measurable.

The counterfactual test

Here’s the diagnostic, and you can run it on your existing case studies this afternoon.

Take any sentence in the piece that describes what your firm did. Consider whether a competent competitor might have chosen differently.

“We mapped the market thoroughly” is uninformative because no firm claims a partial map.

“We excluded every candidate whose only scaling experience came from a company that already had a platform team, which cut the viable pool from thirty-one to nine” is a defensible filter because a competent competitor could absolutely have gone the other way, and plenty would have. In that sentence, you described a decision you owned, with a consequence you accepted.

Treat your marketing as a test. If nobody could have chosen differently, you haven’t described a choice.

What goes in the decision log

To capture those lines, you need to do it while the search is running, they can’t be reconstructed a year later.

Have the lead consultant keep a short running note on each mandate with four things: 

• The moment the brief changed (and why)
• The excluded candidate profile(s)
  The objection that almost cost the placement
• The trade-off you proposed and the client’s initial resistance

Four lines per search. The search takes only minutes, and the results are hard to retrieve afterward

On confidentiality, the rule I’d apply is to anonymize client details while describing the setup. “A 400-person infrastructure software company,” “a post-Series C,” “eighteen months into a cloud migration” gives buyers concrete context without names. The decisions stay in. It’s the logo that comes out, which is a pleasant irony given what most firms currently publish.

Look back after twelve months and analyze both attributed and unaccounted outcomes. A case study that says “product churn fell from 14% to 9% over the following year, though a pricing change landed in the same quarter” is more persuasive than a clean claim, because the restraint tells the reader you weren’t willing to overstate the rest of it either.

Why the story form does the work

One last piece of evidence, because it explains why any of this beats a bullet list.

Readers absorbed into narratives developed stronger story‑consistent beliefs, and more favourable evaluations of the people in it. And they remained consistent even when participants knew the story was true or made up. This finding is from Green and Brock’s narrative transportation experiments (four studies — 97, 69, 274, 258 participants; Journal of Personality and Social Psychology, 2000). 

That research used general readers and fictional narratives, not boards evaluating search firms, and it’s twenty-six years old. I maintain that the mechanism still applies here, because a decision narrative is the only format that lets a buyer follow your reasoning as it unfolds rather than receive its conclusion. That’s my interpretation, not a direct finding.

A bullet prompts the buyer to accept a result. A decision narrative allows them to watch your thought process and decide if they want that thinking for their own problem.

Where to start

Open your best case study and count the sentences a competitor couldn’t have written about their own firm.

A count of zero means you have nothing more than a receipt.
