Hiring a CEO is the most consequential decision a board will make. It is also the search that looks the least like any other recruiting process.
CEO searches are run by boards, not HR departments. They take months of confidential research. They cost hundreds of thousands of dollars. And they are dominated by a small group of firms who have been doing this work for decades — often with the same board directors calling them back for their next company.
This guide breaks down the top CEO executive search firms in 2026, covering the Big Six global players, the boutique specialists that compete with them, how CEO search actually works, and what you should expect to pay.
How CEO Search Differs from Regular Executive Search
Before getting into firms, it helps to understand why CEO searches are treated as a separate category. A CFO or CTO search can look similar to a senior director search scaled up. CEO searches are structurally different.
The board runs the process. A nominating committee or dedicated search committee (usually 3 to 5 directors) sits at the center of the engagement. The search firm reports to the committee, not to the outgoing CEO or HR. Candidate slates are debated in board meetings. Final interviews happen with the full board.
Everything is retained. Contingent search (pay on placement) does not exist at the CEO level. The research depth, confidentiality, and advisory work required cannot be done on spec. All top firms work on a retained basis with fees billed in three installments over the life of the engagement.
Succession planning is part of the work. Top firms do not just fill open seats. They help boards benchmark internal candidates against the external market, run emergency succession drills, and build multi-year pipelines. For many Fortune 500 boards, the search firm is a long-term advisory relationship, not a transactional vendor.
Confidentiality is absolute. Most CEO searches happen without the company publicly announcing the role. Sitting CEOs approached as candidates cannot risk exposure at their current employer. This is why the research teams at these firms spend as much time managing discretion as they do finding candidates.
If you are thinking about building this kind of practice yourself, we covered the mechanics in our guide on how to start an executive search firm — CEO work sits at the top of the retained-search pyramid.
The Big Six CEO Search Firms
Six global firms dominate CEO and board-level search: Spencer Stuart, Korn Ferry, Heidrick & Struggles, Russell Reynolds, Egon Zehnder, and Boyden. Between them, they place the majority of Fortune 500 and FTSE 100 CEOs. Here is how they differ.
Spencer Stuart
Spencer Stuart is consistently ranked as the leading firm for large-cap CEO search. They place more S&P 500 CEOs than any other firm and run one of the most developed board practices in the industry. Founded in 1956, they operate from over 55 offices globally. Their CEO Succession practice is a well-known benchmark, and their annual board studies shape how directors think about governance. If a Fortune 100 board is running a CEO search, Spencer Stuart is usually on the shortlist.
Korn Ferry
Korn Ferry is the largest of the Big Six by revenue and headcount, with a broader service portfolio than any competitor. Beyond executive search, they own significant consulting, assessment, and leadership development businesses. For CEO searches, they bring proprietary assessment tools (Korn Ferry Assess, KF4D) that appeal to boards wanting quantified candidate evaluation. Their scale can be an advantage for global multi-country searches and a drawback for boards wanting a boutique touch.
Heidrick & Struggles
Heidrick & Struggles is the publicly traded veteran of the group (NASDAQ: HSII), founded in 1953. They have a strong CEO and board practice with particular depth in financial services, technology, and industrial sectors. Their Heidrick Consulting arm handles culture and leadership assessment work, which they often bundle into CEO searches. They tend to move slightly faster than Spencer Stuart on comparable mandates, though this varies by consultant.
Russell Reynolds Associates
Russell Reynolds is privately held, which they cite as an advantage for confidentiality-sensitive searches. Their CEO and Board Advisory practice is considered one of the strongest in the industry, and they publish well-regarded research on leadership transitions. They tend to be the preferred firm for boards that want a close advisory relationship rather than a transactional vendor.
Egon Zehnder
Egon Zehnder is the only major firm that operates as a single global partnership with a no-equity-for-founders structure and flat-fee billing. They do not bill as a percentage of first-year compensation — they charge fixed fees negotiated upfront. This model appeals to boards who dislike the incentive misalignment of percentage-based fees. They are particularly strong in European CEO search and in family-business succession work.
Boyden
Boyden is the oldest firm in the group, founded in 1946, and operates through a partner-led office network spanning 75+ offices. They are often positioned as the sixth seat at the Big Six table, particularly strong for mid-cap and private equity-backed CEO searches. Boards that find the top five too expensive or too process-heavy often end up with Boyden.
Boutique and Specialist CEO Search Firms
Not every CEO search needs a Big Six firm. For venture-backed startups, private equity portfolio companies, and specific industry verticals, boutique specialists often deliver better results at lower cost and faster timelines.
True Search
True Search is the dominant firm for venture-backed CEO and executive search. Founded in 2012 and backed by growth equity investors, they placed more venture-backed CEOs than any other firm in the last several years. Their tech platform (Thrive) gives clients real-time search visibility that older firms cannot match. Best fit for Series B through pre-IPO technology companies.
Daversa Partners
Daversa Partners is another venture-focused firm with particular depth in consumer, fintech, and SaaS. They are known for close relationships with top-tier VC firms and can move faster than the Big Six because they work within a narrower network. For a first-time venture CEO hire, Daversa is often on the top of founder recommendations.
Crist | Kolder Associates
Crist | Kolder is a boutique focused exclusively on board-level and CEO/CFO search for public companies. They publish the widely-read Volatility Report tracking CEO and CFO turnover across the Fortune 500 and S&P 500. Despite their small size, they compete directly with the Big Six on large public-company mandates and win regularly on reputation and focus.
For specialized verticals, industry-specific boutiques often outperform generalists. Energy boards, for example, usually work with firms that have deep sector networks — we covered this dynamic in our guide to oil and gas executive search. The same logic applies to healthcare, biotech, and financial services.

Typical Fees and Timeline
CEO search fees sit in a different universe from functional executive search. The standard model at most of the Big Six is one-third of the CEO's first-year total cash compensation, billed in three equal installments: one on engagement, one on candidate slate delivery, and one on offer acceptance. For a CEO with a $1.5M first-year package (base plus target bonus), expect roughly $500K in search fees.
On top of that, boards pay for research expenses (typically 10 to 15% of the fee), candidate travel, and assessment work. All-in cost for a large public-company CEO search commonly lands between $500,000 and $1.2 million. Fortune 100 searches involving multiple finalists, global travel, and extensive assessment can exceed $1.5M.
Egon Zehnder is the notable exception. They charge flat fees negotiated upfront based on scope rather than a percentage of compensation. This removes the awkward incentive to push candidates toward higher packages and is often preferred by boards who dislike the percentage model.
Timeline breakdown:
- Weeks 1-3: Engagement, position specification, board committee alignment
- Weeks 4-10: Research and long-list development (typically 50-200 target profiles)
- Weeks 10-16: Candidate approaches and initial interviews
- Weeks 16-22: Short-list presentations, board interviews, assessment
- Weeks 22-30: Final interviews, reference checks, offer, close
Expect 20 to 30 weeks from engagement to signed offer for a public-company CEO search. Venture-backed and PE-backed searches typically compress this to 12 to 20 weeks.

How to Choose the Right CEO Search Firm
Picking a firm is less about brand and more about fit. A few questions to work through with your board committee:
What stage is your company? A seed-stage startup does not need Spencer Stuart. A Fortune 100 refresh does not belong at a boutique. Match the firm to the size and complexity of the mandate. For venture-backed companies, True Search or Daversa will usually outperform. For public-company succession, the Big Six are the default.
How much board advisory do you need? If your nominating committee wants a long-term advisory relationship — annual succession reviews, board composition advice, leadership development — Russell Reynolds, Spencer Stuart, and Egon Zehnder lead here. If you want a focused, transactional placement, Boyden or a boutique will be leaner.
Are you worried about confidentiality? All top firms handle discretion well, but sitting CEOs approached for your role care about who is making the call. A well-known partner at Russell Reynolds or Spencer Stuart opens doors that a less-known consultant cannot. Ask about the specific partner leading your search, not just the firm.
What is your industry? Sector depth matters. Financial services CEO searches often go to Heidrick. Technology goes to Heidrick, True Search, or Spencer Stuart. Healthcare has specialist firms worth considering. Do not hire a generalist if a specialist exists in your vertical.
How does this fit your broader hiring ecosystem? CEO search is one piece of a larger executive hiring strategy. Boards thinking about integrated hiring ecosystems often coordinate CEO search with CFO, CHRO, and board refresh work across multiple firms — or consolidate everything with one provider in exchange for volume discounts. And if your company is also looking at broader talent operations, it is worth comparing how recruitment outsourcing services handle the layers below the CEO search.
Frequently Asked Questions
How much does it cost to hire a CEO search firm?
Retained CEO search fees typically range from $300,000 to $1 million or more. The standard model is one-third of the CEO's first-year total compensation, billed in three installments. For a CEO with a $1.5M total package, expect fees around $500K. Large-cap and Fortune 500 searches can exceed $1M when factoring in research, assessment, and board advisory work.
How long does a CEO search take?
Most CEO searches take 4 to 9 months from engagement to signed offer. The Big Six firms average 5 to 6 months. Boutique firms can sometimes move faster for specific verticals. Expect an additional 1 to 3 months for transition and onboarding. Urgent replacement searches (interim CEO plus permanent hire) can compress the timeline but usually cost more.
What is the difference between retained and contingent CEO search?
CEO searches are almost always retained, meaning the firm is paid in installments regardless of outcome. Contingent search (only paid on hire) is standard for mid-level roles but does not work for CEO-level placements because of the research depth, confidentiality requirements, and board involvement required. Any firm offering contingent CEO search is a red flag.
Do CEO search firms handle succession planning?
Yes. The top firms (Spencer Stuart, Heidrick, Russell Reynolds, Egon Zehnder) all have dedicated board and CEO succession practices. They help boards build internal talent pipelines, benchmark internal candidates against external markets, and run emergency succession drills. Succession advisory is often billed separately from placement.
Should a tech startup use a Big Six firm for CEO search?
It depends on stage. Early-stage startups (Series A/B) typically work better with boutique firms like Daversa Partners or True Search that understand venture-backed dynamics. Later-stage and pre-IPO companies often engage Spencer Stuart or Heidrick for the board credibility and global reach. Boutiques are usually faster and cheaper; Big Six brings institutional depth.
How involved should the board be in a CEO search?
Heavily. The board search committee typically meets with the firm weekly, reviews candidate slates, participates in interviews, and makes the final hiring decision. Unlike functional executive roles where HR drives the process, CEO searches are board-led. The search firm partners with the committee rather than reporting to a single hiring manager.
