Executive Search vs In-House Recruiting: How to Decide

When a senior role opens, the first decision is who runs the search. A retained executive search firm brings research, reach to people who are not looking and a process built for confidential hires, for a retainer that is generally due whether or not you hire its candidate. Your own recruiting team knows the business, its culture and often the candidates, and its cost is mainly its time, but it may not reach the people you need.

This guide sets out when each route fits, what a retained search costs and what the contract usually covers, how to run a senior search yourself, and what six firms offer, including the pieces you can buy while keeping the search in-house.

Executive search firm or in-house team: how they compare

Korn Ferry's executive search FAQ (opens in a new tab) describes recruitment as advertising a role so that active job seekers apply, and executive search as researching target companies and approaching people who are not looking. A "headhunter" is a recruiter who approaches prospective candidates directly. Your own team can use those search methods too, as the steps below explain. Search firms are paid in two ways: Heidrick & Struggles' 2024 annual report (opens in a new tab) explains that retained firms are generally paid whether or not the client hires their candidate and work exclusively, while contingency firms are paid only when they place someone.

The table compares a retained search with a search run by your own team. The cost and restriction rows come from the firms' annual reports; the rest is the practical difference between the two routes.

Before choosing either route, name the person who will own the search, and compare the fee with the time your team can give it and the cost of leaving the role open.

When a search firm earns its fee

Consider a retained firm when your team lacks the time, access or expertise for one of these situations:

• The search must stay confidential. Replacing an incumbent who has not yet left is hard to run from your own inbox. Korn Ferry's FAQ makes the same point: a firm can source candidates discreetly before anyone announces a vacancy.
• The people you want are not looking. When the strongest candidates hold the same job at another company, someone has to find them, approach them and keep them interested. That research and approach is the core of a search firm's process.
• Nobody inside can judge the function. If nobody on your team has the expertise to assess a chief information security officer, a firm with a record of filling that role can bring a useful reference point.
• The hire is a CEO or a board seat. The board needs a view of the candidates that does not come only from the executives who will report to the new leader, and an outside firm can give it.
• The offer will be complex. Equity, deferred pay and bought-out awards can be hard to price from inside. Heidrick's 2024 report lists helping clients structure compensation packages as a step in its searches, and Korn Ferry's search page says it builds salary benchmarking into each search.

Each of these advantages has a case where your own team does better. A global network adds little if it cannot reach leaders who know a hospital system's state regulators. A firm known for one sector may not have the contacts for a role that is changing, such as a pharmaceutical research leader who now needs data science experience. A confidential CFO search can backfire in a company going through a restructuring where staff expect openness about leadership changes. All three are hypothetical, and they are reasons to test a firm's network and approach against your brief.

When to keep the search in-house

Your own team may be the better choice when it has the time to run the search and:

• You know the market. In a specialized field where your leaders already know most of the plausible candidates, a firm's research adds little.
• You have credible internal candidates. If your best option may already work for you, an assessment of the internal candidates is the first step. Russell Reynolds Associates publishes a case in which a public industrial company had the firm assess its COO and its newer CFO as CEO successors, then promoted the CFO.
• You hire this kind of role often. A company opening several regional general manager roles a year can build the process once and repeat it.
• Your target companies are off limits. Korn Ferry's annual report (opens in a new tab) says it agrees, or chooses, not to recruit from certain clients for a period when searching for others. If your best candidates work at a large firm's clients, that firm may not be able to approach them. Ask before you sign, and if the conflict is real, run the search yourself or choose a firm without it.

You can also combine the two. Run the search internally and buy what is missing, such as an assessment of the finalists, an interim executive to hold the role while the search runs, or recruitment process outsourcing (RPO) when the senior hire is one of many. The firms below offer different combinations of these; ask whether the support you need is available for a search your team runs.

What a retained search costs and what the contract covers

Korn Ferry's annual report for its fiscal year to April 2026 says its search fee is generally one-third of the placed candidate's estimated first-year cash compensation, plus a percentage of the fee for indirect expenses, with a further fee when the final pay is higher than the estimate.

Heidrick & Struggles' report for 2024, filed before it became a private company (opens in a new tab) in December 2025, gave more detail. It billed the retainer in three equal parts over three months, starting in the month the client accepted the contract. Indirect expenses were a percentage of the retainer, with dollar limits per search, and direct expenses were billed as they occurred. Its average revenue per executive search was $146,000 in 2024.

That report said Heidrick's executive search contracts included a replacement guarantee: if the client hired its candidate and then dismissed that person for performance within a specified period, it ran another search free of charge apart from expenses. Ask any firm whether it offers one, and read the period and the conditions in your own contract.

Timelines are less settled. Russell Reynolds Associates' executive search page (opens in a new tab), read in October 2026, says its process typically delivers a shortlist of qualified candidates within eight weeks, depending on the position and market conditions, and separately that it can recruit leaders "in as little as 14 weeks", without saying which stage that ends at. Heidrick's 2024 report recognized search revenue over about six months, its expected average period of work on a search. Alpha Apex Group publishes a firm-wide average time to fill for full-time hires, described in its entry below. Egon Zehnder, Korn Ferry and Spencer Stuart publish no search timeline on the pages read. The executive search fee guide compares fee structures in more detail.

Whichever route you choose, define the job first

A search, whoever runs it, can only find what you describe. In 2019 I talked on my podcast about handing off sales at Lead Cookie, the company I ran then. The first time, I handed off sales before the process was ready, and the new salesperson made some sales he should have turned away and turned away some good prospects. The second hand-off worked because there was an established process for the new salesperson to learn.

A senior hire works the same way. Before you brief a firm or your own team, I'd write down what the role must deliver in its first 90 days and its first year, who it reports to and how you will judge it. If you cannot write that, no search route will fix it, and it may be a sign to learn the function yourself before you hire for it.

How to run a senior search in-house

If you keep the search, give it the structure a firm would. Korn Ferry's FAQ lists ten steps a firm follows, from discovery to closing the offer. The five below adapt them for an internal team.

1. 1

   Write the brief and the scorecard

   Name the outcomes the role owns, the reporting line, the experience that is essential and what can be learned. Agree the compensation range, how it fits your internal pay structure and who approves it. Agree all of it with every interviewer before the first call, so the panel is judging the same job.

2. 2

   Build a list of target companies and people

   List the companies where someone already does this job at the right scale, then the people in those roles and one level below. Add your own network and referrals.

3. 3

   Approach candidates discreetly

   Keep the circle of people who know about the search small, use a personal approach from a senior leader, and agree a non-disclosure agreement where the search is sensitive. A candidate who is not looking has a job to protect. Explain the business's challenges honestly, so candidates understand what they would be joining.

4. 4

   Interview the same way every time

   Ask every finalist the same core questions about the outcomes in the brief, score the answers against the scorecard and compare notes as a panel. Agree reference contacts with the candidate before you call anyone, then seek views from people who have worked with them while keeping the search confidential.

5. 5

   Keep candidates informed and close carefully

   Give every candidate a timetable and stick to it. Prepare the offer terms before the final interview, including what the first year will look like.

Questions to ask before you sign with a search firm

If your team has the time, the market knowledge and the judgment of the function to run the search, keep it in-house and buy the support it lacks. Which part of your next senior search does your team not yet know how to do?
