The right retained executive search firm should be able to show relevant search experience and identify who will run the assignment. It should also explain how it will reach executives outside its existing network, and buyers should know which target companies are restricted by off-limits agreements. These details show what the client will receive once the search begins.
For a CEO or board, the decision becomes harder when several firms can point to decades of executive search experience. The useful comparison is narrower: has this team worked in the leadership market the company needs to enter, and can it show what happened on comparable assignments?
A firm that regularly recruits CFOs for public companies faces a different candidate market from one searching for a VP of AI at an enterprise software company. A Chief Robotics Officer or VP of Engineering can create another problem because credible candidates may hold several different titles.
What Should You Look for in a Retained Executive Search Firm?
A retained executive search firm should be evaluated on comparable assignments, the people assigned to the search, candidate access, and evidence from previous work. A well-known firm can still be the wrong choice if the team handling the assignment has limited experience in the market the client needs to reach.
Before selecting a firm, buyers should be able to answer four questions:
- Has this team completed searches that resemble ours?
- Who will personally lead the assignment?
- How will the firm identify executives beyond people it already knows?
- Are any target companies unavailable because of off-limits agreements?
These questions move the comparison from firm credentials to the work that will happen after the engagement begins.
Price belongs in the discussion, though it doesn't answer them. Two retained search firms can charge similar fees while providing different levels of partner involvement or original market research.
Relevant Experience Should Match the Candidate Market
Relevant experience means recent work in the candidate market surrounding the role. A long list of searches across unrelated functions provides less useful evidence. A company hiring a VP of AI should ask which AI leadership searches the firm has completed and which employers it would consider part of the target market.
Industry experience matters when it changes the candidate pool. Recruiting a technology executive into aerospace and defense can require familiarity with a different group of executives from recruiting the same title into healthcare. Previous assignments should give the search team a useful starting view of where credible candidates sit.
That doesn't require finding a firm that has filled the identical title at an identical company. Emerging leadership functions rarely fit that neatly. A VP of AI candidate could currently hold a Head of Applied AI position or a senior engineering role. Smartsheet's first Chief AI Officer, for example, came in from a CTO title at a different company. The search team needs enough familiarity with the field to recognize relevant experience when titles don't match.
Recent examples are more useful than broad claims of specialization. Look at the role involved and why the eventual candidate matched the mandate.
Partner Involvement Matters After the Search Begins
The partner presented during the selection process should have a defined role once the search begins. Buyers need to know who will map the market, speak with candidates, assess finalists, and communicate with the hiring team throughout the assignment.
The person who wins the engagement isn't always the person doing most of the work afterward. A firm's credentials can therefore tell a buyer little about the individual partner's knowledge of the target market.
Find out who conducts the first substantive candidate conversations and who decides which executives reach the client. For a specialized technology search, those conversations require enough subject knowledge to distinguish similar-looking careers. A recruiter assessing a VP of Engineering candidate needs to establish what the executive personally owned and the conditions under which the work was done. Employer and title alone won't answer either question.
Senior involvement also affects candidate outreach. Executives who aren't looking for a new position need a credible reason to consider the opportunity. The person making that approach represents the mandate before the candidate ever meets the client.
How Does the Firm Identify Candidates Beyond Its Existing Network?
A retained search firm should build a fresh market map for each assignment. Existing contacts can contribute to that research without defining the entire candidate pool. Previous relationships can open doors, but the strongest candidate for a particular mandate could be someone the firm has never approached before. The firm should be able to explain how it would define the initial market for the specific search.
For established positions, research could begin with executives at companies that share relevant characteristics with the client. Newer functions require a wider view. A company hiring its first senior AI leader could find credible candidates under several titles, making title-based sourcing too restrictive.
The search also needs to reach executives who aren't applying for jobs. The work then shifts from screening available applicants to identifying people whose experience fits the mandate and establishing enough interest for a conversation.
AI can make parts of this research faster by identifying career patterns across larger candidate pools. Once those names have been found, the search team still has to decide who warrants an approach and why that executive could fit the assignment.
What Are Off-Limits Restrictions in Executive Search?
Off-limits restrictions determine which companies an executive search firm cannot recruit from during a particular period, reducing access to candidates a client might otherwise target. Buyers should identify those restrictions before appointing a firm, especially when the relevant executives are concentrated among a small group of employers.
A search firm could have relationships with companies that would otherwise be obvious sources for the assignment. Depending on its agreements and policies, executives at those organizations could be unavailable for recruitment.
The effect becomes greater in concentrated leadership markets. A company seeking experience from a short list of direct competitors could lose access to part of its preferred candidate pool.
Request the restrictions that apply to the proposed mandate. A general description of the firm's policy won't show how much of the desired market is accessible.
How Should You Evaluate a Search Firm's Track Record?
A useful track record shows what the firm has completed on assignments comparable to yours and provides enough detail to judge the relevance of those results. Total placements or decades in business provide context, while recent searches reveal more about the team's experience with the leadership market being targeted.
A relevant comparison for a CTO mandate could involve companies facing a similar technical problem or stage of growth. For a VP of AI search, the scope of the previous mandate can tell the buyer more than an identical job title.
Client references provide another source of evidence. Ask how closely the candidate market matched the original brief and how the search team responded when early market feedback challenged the client's assumptions.
How Should an Executive Search Firm Assess Candidates?
Candidate assessment should focus on the work the incoming executive will be expected to own, with evidence from comparable situations carrying more weight than title similarity. Clients should understand that assessment method before the search starts because it determines which candidates eventually reach the interview stage.
A résumé establishes where an executive worked and which positions that person held, while providing less evidence about what the executive personally owned.
Consider two CTO candidates who have both led large engineering organizations. One could have inherited an established team with mature systems. The other could have built the function during a period of company growth. Identical titles can therefore represent very different operating histories.
The search firm needs to know which history matches the client's mandate. This becomes harder in newer AI roles. Companies use VP of AI, Head of AI, Chief AI Officer, and other titles for positions with different levels of authority. Assessment has to establish what the executive personally built or led.
References can test those claims with people who worked alongside the candidate. They can also expose differences between what appears on a résumé and how the executive operated when difficult decisions arose.
Before appointing a firm, find out how candidates will be assessed and what evidence will accompany each recommendation.
What Should a Retained Search Firm Provide During the Search?
Clients should receive a clear view of the candidate market and evidence of how the assignment is progressing. A retained engagement runs over a period of time, so the firm's contribution should be visible before a shortlist arrives.
Early market research can reveal that the original candidate specification needs adjustment. The proposed compensation could sit below what qualified executives expect, for example. The available candidate pool could also be narrower than the company assumed.
That information is most useful while the client still has time to respond.
Candidate reporting should provide enough context for the hiring team to understand why an executive is being recommended. For a senior search, forwarding a résumé with a short biography leaves much of the evaluation work with the client.
Market feedback belongs in those updates too. If credible candidates repeatedly raise the same concern about reporting lines or authority, the client needs to know. The pattern could indicate that part of the mandate needs to change.
Before signing, determine how often the firm reports to clients and what those updates contain.
How Much Should Retained Executive Search Cost?
Retained executive search fees typically reflect the seniority and difficulty of the assignment, with payment made across stages of the engagement. Buyers comparing fees should examine what each proposal includes because a percentage alone says little about the research or senior attention behind the search.
Christian & Timbers' existing retained-search content cites fees of roughly 25% to 35% of first-year cash compensation.
For buyers comparing firms, the more useful question is what the quoted fee covers.
- Does the firm conduct original market research?
- Who handles candidate outreach?
- How are references conducted?
- What happens if the mandate changes after the market has been mapped?
The contract should also state how expenses are handled and what happens if the client pauses or cancels the assignment. Any replacement provision should be clear before the engagement begins.
A fee comparison becomes more meaningful once those terms are visible. Two proposals expressed as the same percentage of compensation can represent different search models.
What Questions Should You Ask a Retained Executive Search Firm?
The best questions force a retained executive search firm to explain how it would run your specific assignment. General descriptions of the firm's capabilities provide less useful evidence. Buyers should leave the selection process knowing who will lead the work and what evidence will determine who reaches the interview stage.
Questions worth asking include:
- Which recent searches are closest to this assignment?
- Who will personally lead the search after we sign?
- Which companies would you target first, and why?
- Which target companies are currently off-limits to your firm?
- How will you identify candidates whose current titles differ from ours?
- What evidence do you require before presenting a candidate?
- What will we receive in each search update?
- How do you respond when early market feedback challenges the original brief?
The answers should become more specific as the conversation progresses.
“We have a strong technology network,” for example, says little about a VP of AI assignment. A useful answer identifies the candidate pools the firm would investigate and explains their relevance to the mandate.
The same test applies to assessment. Saying that candidates undergo extensive interviews doesn't tell a client what will be tested. The firm should be able to explain what it needs to establish about an executive before making a recommendation.
How Do You Compare Retained Executive Search Firms?
Compare retained executive search firms against the same assignment and require evidence for each claim. The comparison should show how much of the relevant candidate market each firm can reach, who will lead the work, how executives will be assessed, and what the team has completed on similar assignments.
[Table 1]
The weighting should depend on the assignment.
Off-limits restrictions could carry greater weight when the desired executives are concentrated among a small number of companies. Partner experience could matter more when the position is new and the client needs help defining the mandate before outreach begins.
Published rankings of top retained executive search firms can help create an initial shortlist. They don't tell a board which partner will run its assignment or how much of its target candidate market that firm can access.
Specialization Matters When Titles Hide Different Responsibilities
A specialized executive search firm is useful when understanding the candidate market requires knowledge beyond the job title. This occurs in AI and other technical functions where similar titles can represent different responsibilities and credible candidates could currently work in adjacent roles.
A VP of AI search provides a clear example. One company could give the role responsibility for internal AI deployment. Elsewhere, a VP of AI could own model development. Searching both assignments against an identical candidate profile would miss that difference.
Specialization can matter in aerospace and defense or robotics for the same reason. The operating environment changes which experience transfers well into the new role.
Evidence should determine how much that specialization is worth. Previous searches can show how the firm's sector knowledge affected where it looked for candidates or how it evaluated them. A sector label on a services page can't establish either point.
AI Is Expanding Executive Search Research
AI can shorten parts of executive-search research by identifying relevant career patterns across larger candidate pools. It can be especially useful when a search crosses conventional title boundaries, although candidate discovery represents only part of a retained assignment.
A VP of AI search could include executives whose current titles don't contain “VP of AI.” Research tools can surface leaders working under adjacent titles and give the search team a wider initial market to examine.
The search team still has to establish what each executive personally owned and how that experience relates to the new mandate. Confidential outreach depends on the quality of the conversation with an executive who could be satisfied in a current position.
C&T's existing retained-search coverage makes a similar distinction: AI can speed up market research and identify executives beyond obvious title matches, while later stages depend on understanding what the candidate has done and how that experience transfers.
How Does Christian & Timbers Approach Retained Executive Search?
Christian & Timbers has completed more than 5,000 executive searches over four decades, including C-suite and senior technology mandates. Its published work includes searches across AI and enterprise technology, with additional experience in robotics and aerospace and defense.
Recent appointments provide a more specific view of that work. Christian & Timbers placed Ashok Paranjothi as SVP of AI at Acosta Group and Sylvia Isler as CTO at Atropos Health. The searches covered different leadership needs, from enterprise AI deployment at Acosta Group to the engineering foundation required to move Atropos Health's healthcare technology from research into production.
For AI leadership mandates, the firm evaluates what candidates have taken into production and the results connected to that work. Its searches can extend beyond identical titles when the relevant leadership experience sits elsewhere in the market.
Companies considering Christian & Timbers can apply the same evaluation used throughout this guide. They should know who will lead the mandate and how the candidate market will be defined. The firm should also explain what evidence determines which executives reach the client.
Frequently Asked Questions About Retained Executive Search Firms
1. What Is a Retained Executive Search Firm?
A retained executive search firm works exclusively on a defined senior-level hiring assignment and is typically paid across stages of the engagement. The fee supports dedicated research and outreach throughout that mandate.
2. What Are the Top Retained Executive Search Firms?
The best retained executive search firm for an assignment depends on access to the relevant candidate market and the experience of the team handling the mandate. Overall reputation can help create an initial shortlist, but buyers still need to compare the partners proposed for their specific search.
3. How Do Companies Compare Retained Executive Search Firms?
Companies can compare retained executive search firms by giving each one the same mandate and requesting specific evidence about candidate access, previous assignments, assessment methods, and search leadership. Using the same criteria makes substantive differences between proposals easier to identify.
4. What Is an Off-Limits Policy in Executive Search?
An off-limits policy restricts an executive search firm from recruiting certain employees from current or recent clients for an agreed period. Buyers should determine which restrictions apply to their proposed assignment because those agreements can affect access to executives at target companies.
5. How Long Does a Retained Executive Search Take?
Retained executive search timelines depend on the seniority of the position and difficulty of the candidate market. Christian & Timbers' existing retained-search content cites an average timeline of around 123 days, although individual assignments can differ according to the mandate and available candidate pool.
6. Is Retained Executive Search Only for C-Suite Hiring?
Retained executive search also applies to VP and SVP positions when the candidate market is difficult to reach or the assignment requires confidential outreach. Christian & Timbers' existing guidance identifies VP and SVP appointments among the situations where a retained engagement can make sense below the C-suite.
7. What Should Be Included in a Retained Search Agreement?
A retained search agreement should define the assignment and fee structure while documenting the terms that affect the engagement. Buyers should also understand applicable off-limits restrictions, replacement provisions, expenses, and what happens if the scope changes or the search ends before completion.
8. Should You Choose an Executive Search Firm Based on Price?
Price should be evaluated alongside the work included in the engagement. Two firms charging similar fees can differ in partner involvement, original market research, candidate assessment, or contractual terms, so the quoted percentage alone doesn't establish which proposal offers the better search.
