Top Retained Executive Search Firms in 2026: 9 Firms Ranked, Plus an In-House Option

By Sparsh Goyal, Founder at The Cognitive. Published 2026-11-03 · Last updated 2026-11-04

• The top retained executive search firms are Boyden, Korn Ferry, Stanton Chase and Odgers, with The Cognitive first as the in-house alternative for VP and director seats.
• Korn Ferry and Heidrick & Struggles describe a retainer of about one-third of the hire's estimated first-year pay, owed whether or not anyone is hired.
• Each firm is scored on reach in 30+ countries, interim leaders, senior-led delivery and advisory work, and none publishes a price.

Disclosure: The Cognitive is our product.

The top retained executive search firms are Boyden, Korn Ferry, Stanton Chase, Odgers, Heidrick & Struggles, Egon Zehnder, Spencer Stuart, DHR Global and Russell Reynolds Associates. Boyden suits cross-border searches that may need an interim leader, Korn Ferry the widest footprint, and Stanton Chase buyers who want one partner from start to finish. The Cognitive is listed first as the in-house alternative. It is software a talent team uses to find, email and interview leaders itself, for VP and director seats that do not need a retainer.

The top retained executive search firms in 2026

1. The Cognitive: best for talent teams running their own VP and director searches.
2. Boyden: best for cross-border searches with interim cover.
3. Korn Ferry: best for the widest footprint plus leadership assessment.
4. Stanton Chase: best for one partner from first call to signed offer.
5. Odgers: best for board, CEO and interim work across 33 countries.
6. Heidrick & Struggles: best for CEO and board searches with on-demand leaders.
7. Egon Zehnder: best for CEO succession and board reviews.
8. Spencer Stuart: best for board searches backed by its own board research.
9. DHR Global: best for senior-led searches with a stated average fill time.
10. Russell Reynolds Associates: best for a fast shortlist on CEO and board searches.

U.S. employers announced 1,337 CEO exits in 2026 through September, and 53% of the named replacements "came from inside the company", according to Challenger, Gray & Christmas. The other 47% came from outside. When that outside search goes to a retained firm, Korn Ferry and Heidrick & Struggles describe a fee of about one-third of the new leader's first-year pay.

How the retained search firms compare

A "No" means the firm does not say it offers this, not that it cannot. Ask about any No that matters to you. DHR Global's 22+ is its country count; the 60+ on its homepage is markets served. Odgers, Egon Zehnder, Spencer Stuart and Russell Reynolds do not describe their fee model on their sites, so ask whether the search is retained.

How the list was ranked

These firms are ranked using feedback from recruiters the founder talks with on LinkedIn, plus each firm's own site and, for the two firms that have filed one, its annual report.

Every firm here names CEO and board search among its services and appears on 2026 lists of top executive search firms. Each firm then gets one point for each of four things a buyer of a retained search tends to need:

• Reach in 30 or more countries: matters for cross-border mandates and global candidate pools.
• Interim or on-demand leaders: matters when the seat is empty before the search ends.
• Senior people on the search throughout: the firm says partners or its most senior people run the work, not junior staff after the pitch.
• Leadership assessment or advisory alongside search: matters for succession planning and for judging finalists.

Higher scores rank first. Ties go to the larger country count the firm gives. Heidrick & Struggles' count comes from its last annual report as a listed company (2024). No firm publishes a price, so price does not separate them.

The Cognitive sits first on a different rule. It is the one option here with a published monthly price instead of a fee tied to the hire's pay, and the only one a talent team runs itself.

What is retained executive search, and when is a retainer worth it?

Retained executive search is a search paid for up front and run on an exclusive basis. Heidrick & Struggles' 2024 annual report says retained firms "generally are compensated for their services regardless of whether the client employs a candidate identified by the search firm". By contrast, "contingency search firms are compensated only upon successfully placing a recommended candidate."

Spencer Stuart, Heidrick & Struggles, Russell Reynolds, Egon Zehnder and Korn Ferry are often called the big five. The executive search firms guide covers them and sets the two fee models side by side.

A retainer buys a dedicated team, exclusivity and discretion. It earns its fee on a confidential CEO replacement, a board seat, or a role with a very small pool of candidates. Boyden, for one, lists "replacement searches, leadership transitions, pre-announcement hires" among the confidential searches it runs.

For a VP of sales or a director of finance, the case is weaker. Korn Ferry's 2026 annual report names competition from "in-house human resource professionals" whose reach has grown through online profiles and "enhanced social media-based or AI-based search tools".

How much do retained search firms charge?

No firm on this list puts a price on its website. The two that filed annual reports describe the same model:

• The base fee: about one-third of the role's estimated first-year pay. Korn Ferry says "generally one-third of the estimated first-year cash compensation of the placed candidate".
• When it is billed: Heidrick's 2024 annual report says it billed "in one-third increments over a three-month period commencing in the month of a client's acceptance of the contract".
• Expenses: added on top as a percentage of the fee, at both firms.
• The top-up: if the hire's actual pay beats the estimate, Heidrick says firms are often allowed to bill one-third of the excess. Korn Ferry calls this an "uptick fee".

An illustration: a VP role with an assumed $300,000 first-year package carries a retainer of about $100,000. Billed the Heidrick way, that is three invoices of about $33,333 in the first three months, before expenses, owed whether or not anyone is hired. The $300,000 is an example, not a market figure.

Your contract may differ. The recruitment agency fees guide compares other fee models.

How do you choose a retained executive search firm?

Does this seat need a retainer at all?

Ask whether the search must be confidential, whether the pool is tiny, and whether a board is involved. If none of those is true, an in-house team can often run it. Direct sourcing delivers 11% of hires from just 2.6% of applications, according to Gem's 2026 Recruiting Benchmarks Report.

Might the seat be empty before the search ends?

Interim leaders are in demand: 102 interim CEOs exited U.S. employers in 2026 through September, up 70% on the same period of 2025, Challenger found. If a gap is likely, pick a firm that offers interim cover.

Who will actually run the search?

Get the lead advisor's name in the contract. Boyden, Stanton Chase and DHR Global put senior-led delivery in writing on their sites.

What belongs in the agreement?

The AESC Client Bill of Rights lists the lead advisor, scope, timing, "the fees and payment schedule", deliverables, and terms "that might include guarantees, off-limits, conflicts, data management". Off-limits terms set which of your people the firm will not recruit later, so read them closely.

How long will it take?

The AESC says "a successful search can take anywhere from a few weeks to several months". Ask each firm for its timeline by stage.

The in-house pick and 9 retained firms, reviewed

1. The Cognitive: best for talent teams running their own VP and director searches

Verdict: software, not a search firm, for the senior searches a talent team can run without paying a third of the salary.

The Cognitive is AI sourcing and live AI interviews in one account. Describe the leader you need in plain English, then narrow by seniority (CXO, VP, Head, Director), current or past employer, title and location. It searches about 900M public profiles and gives a short reason for each match.

Each person a search shows costs 1 credit. Reveal a personal email for 4 credits, or a phone number for 12 on Pro plans and above.

On Sourcing Pro and above, outreach goes by email from your own mailbox, and follow-ups stop when someone replies. When a leader replies with interest, you invite them to a live two-way AI video interview, held in any of 9 languages. Candidates are told an AI runs it and that the employer's team makes every hiring decision.

The scored report can go to a search committee by a read-only link. On Sourcing Max, Interview Pro and Business plans, it syncs with 100+ ATS. More on the executive search solution.

Best for: in-house talent teams filling VP, head-of and director seats that would otherwise go to a retainer.

Watch out for: no consultant, no retained search, no reference checks and no off-limits protection. Outreach comes from your own mailbox under your company's name, so it cannot hide the employer on a confidential CEO replacement.

Pricing model: AI Sourcing and AI Interviews are separate monthly plans. Plans start at $99 a month (see pricing). Credits cover usage, and a 20-minute interview is 100 credits.

2. Boyden: best for cross-border searches with interim cover

Verdict: the only firm here that scores on all four checks, and the only one that sets out its timeline stage by stage.

Boyden describes itself as "a global executive search firm with more than 75 offices in over 45 countries", working in a "partner-led, high-touch" way. Alongside search it sells interim management and leadership consulting.

A typical retained search takes about 9 to 14 weeks. Boyden splits it into discovery (1 to 2 weeks), research and assessment (6 to 8), then interviews and offer (2 to 4). It says it ranks seventh on Forbes' 2026 list of America's Best Executive Recruiting Firms.

Best for: companies hiring across borders that may need an interim leader while the search runs.

Watch out for: across 75+ offices the lead partner matters more than the brand, so meet the one who will run your search before you sign.

Pricing model: retained, quoted per search; no price on its website.

3. Korn Ferry: best for the widest footprint plus leadership assessment

Verdict: the largest firm here, with assessment and interim services under one roof.

Korn Ferry's latest annual report lists 98 offices in 51 countries and says its recruitment work is "performed on a retained basis". It sells Board & CEO Services, and its revenue includes interim services. Its executive search page promises to "Find the Next Great Leader to Take Your Organization to the Top".

Korn Ferry says candidates hired using its assessments are eight times more likely to be promoted within three years.

Best for: large companies that want search, assessment and interim leaders from one firm.

Watch out for: its site does not promise partner-led delivery, so ask who does the day-to-day work.

Pricing model: retained; its filing puts the fee at about a third of first-year cash pay, with expenses on top. No price on its website.

4. Stanton Chase: best for one partner from first call to signed offer

Verdict: the clearest promise on who runs your search.

Stanton Chase calls itself "a top-ranked global retained executive search and leadership advisory firm", founded in 1990. It lists 70 offices in 45 countries and 350 consultants. It says: "The partner who starts your assignment finishes your assignment. No handoffs to junior associates."

Its retained process is branded Search+, and it is a member of the AESC. The firm says it makes 300 CEO and board member placements a year and reports an 8.9 out of 10 customer satisfaction index.

Best for: boards and CEOs who want the same senior person on the search throughout.

Watch out for: no interim management service is listed, so a seat that is already empty needs cover from elsewhere.

Pricing model: retained, quoted per search; no price on its website.

5. Odgers: best for board, CEO and interim work across 33 countries

Verdict: a broad mid-size choice that covers search, board work and interim leaders.

Odgers describes its business as "Executive Search and Leadership Advisory", with over 59 offices in 33 countries. Its services include Board + CEO Services and Interim Management, and it is a member of the AESC.

The firm says it has 200 partners and completed 4,900 searches worldwide over the last three years.

Best for: companies that may want an interim executive and a permanent search from the same firm.

Watch out for: its site does not describe a retained fee model or a search timeline, so get both in the proposal.

Pricing model: quoted per search; fee model not stated on its website.

6. Heidrick & Struggles: best for CEO and board searches with on-demand leaders

Verdict: one of the oldest names in search, now privately owned.

Heidrick & Struggles, founded in Chicago in 1953, calls itself "a leading retained executive search firm" that works "on an exclusive basis". It says its retained search "continues beyond the hire", with support through "interviews, reference checks, negotiations, and onboarding". It has a CEO and board practice and offers on-demand project leaders and interim roles such as an interim chief human resources officer. It also sells leadership advisory, including executive assessment, coaching and CEO succession planning.

Heidrick said in December 2025 that it had become a privately held company, in a deal valued at about $1.3 billion with a consortium of Advent International and Corvex. Its shares no longer trade on Nasdaq, and it keeps its brand. Its last annual report as a listed company (2024) listed 63 offices in 30 countries.

Best for: CEO and board searches where reference checks and onboarding support are part of the brief.

Watch out for: as a private firm it no longer files annual reports, so its fee terms and office count are less public than before.

Pricing model: retained; its 2024 report described a third of estimated first-year pay, invoiced over three months. No price on its website.

7. Egon Zehnder: best for CEO succession and board reviews

Verdict: strongest when the search is part of a wider succession or board question.

Egon Zehnder says its "more than 600 consultants, across 71 offices and 37 countries" work as "one powerful global team", and calls its model a "unique partnership approach". Its services include board director and chair searches, CEO succession design, and board effectiveness reviews. It says it has drawn on more than 1,000 of these reviews.

Best for: boards planning CEO succession over years, not weeks.

Watch out for: no interim service and no timeline appear on its site.

Pricing model: quoted per search; fee model not stated on its website.

8. Spencer Stuart: best for board searches backed by its own board research

Verdict: a partnership firm with deep board work and little detail online.

Spencer Stuart describes itself as "Executive Search, Board & Leadership Consulting", with consultants "across more than 60 offices in over 30 countries" and more than 50 practice specialties. It was founded in 1956. In 1974 its founder sold his shares to employees, which the firm says established its partnership culture. It publishes the annual U.S. Spencer Stuart Board Index.

Best for: boards adding directors who want a firm that studies boards for a living.

Watch out for: its site gives no timeline, fee model or interim service, so the proposal has to carry all of it.

Pricing model: quoted per search; fee model not stated on its website.

9. DHR Global: best for senior-led searches with a stated average fill time

Verdict: a senior-led firm that puts a number on speed.

DHR Global offers "Executive Search and Leadership Consulting" and says "you work directly with our most senior executive search and leadership consulting professionals". It began in 1989 with a focus on retained executive search, then added searches for emerging leaders through Jobplex. It sells Board & Governance Services.

The firm reports 160+ global partners, 83% repeat business and a 94-day average fill time, across more than 22 countries.

Best for: companies that want senior attention and a firm that also fills the level below the C-suite.

Watch out for: fewer countries than the global firms and no interim service listed.

Pricing model: retained, quoted per search; no price on its website.

10. Russell Reynolds Associates: best for a fast shortlist on CEO and board searches

Verdict: the most specific speed promise among the global firms.

Russell Reynolds Associates was founded in New York in 1969. It says its consultants help clients "recruit great CEOs, CxOs, and board members in as little as 14 weeks", with a shortlist "within eight weeks". It has 500+ leadership advisors in 47 offices across 25 countries and an exclusive partnership with Hogan Assessments. It reports a 96% client satisfaction score.

Best for: boards that need a CEO or CxO shortlist quickly.

Watch out for: its site names neither interim leaders nor partner-led delivery, so ask about both.

Pricing model: quoted per search; fee model not stated on its website.

When not to pick The Cognitive

• Nobody may know you are hiring. Outreach goes from your own mailbox, so candidates see the employer. A firm can approach people for a replacement CEO without naming you.
• The seat is empty today. The Cognitive supplies no interim executives. Boyden, Korn Ferry, Odgers and Heidrick & Struggles do.
• The board wants a consultant's judgment. The AI interview gives a scored report and a transcript, not a partner's assessment, references or a negotiated offer.
• You need off-limits protection or a guarantee. Those are contract terms with a firm. Software has neither.

To test the in-house route, pick one VP or director seat you would otherwise send to a retained firm. Write a two-line brief and see which leaders match before you sign. A free 7-day trial, with no card, shows your first 100 people; outreach starts on Sourcing Pro. Start free with The Cognitive.
