Korn Ferry vs Spencer Stuart At A Glance

History And Scale

Spencer Stuart is the older of the two. According to its firm history, Spencer “Spence” Stuart founded it in Chicago in 1956 after working in the executive search division of Booz Allen Hamilton. In 1974 he made his entire shareholding available to a group of employees, creating the partnership culture the firm says it keeps today. Its firm overview lists more than 60 offices in over 30 countries, more than 50 practice specialties and more than 2,200 colleagues worldwide.

Korn Ferry says it has spent more than five decades designing organization structures, hiring talent and advising on rewards and development. It is considerably larger. Its fiscal 2025 annual report lists 103 offices in 51 countries and 9,253 full-time employees, and total fee revenue for the year to April 30, 2025 was $2,730.1 million.

Ownership shapes how much each firm discloses. As a listed company, Korn Ferry publishes revenue by segment and operating data such as consultant numbers. Spencer Stuart, as a private partnership, does not publish current revenue, so direct financial comparisons are limited.

Services And Specialisms

Korn Ferry runs five business lines. In fiscal 2025, Executive Search produced $846.2 million in fee revenue, Consulting $662.7 million, Professional Search and Interim $503.5 million, Digital $363.5 million and RPO $354.1 million, according to its full-year results. The search team had 560 consultants at year end and opened 6,325 new engagements. Korn Ferry’s solutions also include organization strategy, total rewards, leadership development and business transformation.

Spencer Stuart’s offer is narrower and centered on senior leadership. Its capabilities include executive search, board and CEO advisory, CEO succession planning, executive assessment, leadership consulting, and HR and talent advisory. It serves industries including technology, media and telecom, consumer, financial services, healthcare, industrial, private equity, and education and social impact.

Put simply, Korn Ferry can cover almost every part of a talent agenda, from a CEO search to volume recruitment through RPO. Spencer Stuart concentrates on the most senior appointments and the advice that surrounds them.

Leadership And Board Practice

Board work is Spencer Stuart’s signature. The firm says it was the first executive search firm to establish a dedicated Boards Practice, in 1983, and it published the first Spencer Stuart Board Index in the United States in 1987. It now publishes more than 20 Board Indexes a year. The 2025 U.S. Spencer Stuart Board Index was the 40th edition and tracked S&P 500 boards, finding that they appointed 374 new independent directors in the period studied, the fewest since 2016.

Korn Ferry’s Board and CEO Services are broad. They cover board succession and effectiveness, CEO search and succession, CEO development programs such as the Chief Executive Institute, executive compensation, and Board Ascent, which helps executives prepare for their first board role. Where Spencer Stuart leads on governance research, Korn Ferry’s strength is combining board and CEO work with pay design and leadership development.

Assessment And Consulting

Korn Ferry’s assessment operation is very large. Its annual report states that it has conducted more than 108 million assessments, and its Assessment and Succession work uses role Success Profiles to guide hiring, promotion and succession decisions. Its Digital segment sells the Talent Suite software, which reported more than 7,800 clients engaged in fiscal 2025.

Spencer Stuart has offered assessment for decades. Its firm history records the launch of Global Intelligence in 1998, later renamed Executive Assessment Services, and the firm now offers executive assessment and leadership consulting alongside search. The service is focused on senior leaders and leadership teams rather than large-scale workforce testing. Our guide to executive assessment explains the main methods both firms use.

Global Footprint

Korn Ferry’s 103 offices in 51 countries make it the larger network, and it reports its search business across four geographic segments. Spencer Stuart’s more than 60 offices in over 30 countries still cover the major financial and corporate centers. Both firms have offices in major business centers such as Dallas and Toronto, and for most searches in large markets either can reach the candidate pool. Spencer Stuart’s early international history is notable: it opened in Zurich in 1959 and had run searches in 29 countries by 1960.

Partnership vs Public Company

Spencer Stuart’s ownership model is part of its identity. Since 1974 the firm has been owned by its employees and partners, and its firm overview describes it as privately held since 1956. Partner ownership tends to appeal to boards that want advice from people with a direct stake in the firm’s long-term reputation rather than its quarterly results.

Korn Ferry’s listing on the New York Stock Exchange brings a different kind of accountability. It publishes quarterly results that show how each business line is performing. In the fourth quarter of fiscal 2025, its executive search fee revenue rose 14% year over year to $227.0 million. For clients, that transparency makes it easy to see where the firm is investing.

Questions To Ask Both Firms In A Pitch

Running a short competitive pitch is the best way to decide between two firms of this caliber. These questions help separate the brand from the team you will actually work with.

Who Will Lead The Search Day To Day?

Ask for the name of the partner who will own the assignment, how many other searches they are running, and who will handle research and first-round calls. A senior partner who appears only at the pitch and the final interview is a warning sign at any firm.

Which Comparable Searches Has The Team Completed?

Ask for recent searches at the same level, in the same sector and of similar complexity. References from boards or CEOs who hired through the same partner are more useful than firm-wide statistics.

Which Companies Are Off-Limits?

Large firms work for many clients and cannot recruit from organizations they currently serve. Ask each firm to confirm, in writing, which of your target companies it cannot approach. The bigger the firm, the more important this question becomes.

How Will Candidates Be Assessed?

Both firms offer assessment, but the depth varies by assignment and by what you pay for. Ask what assessment is included in the standard fee, what costs extra, and how results are shared with the hiring committee.

Who Each Firm Suits

Choose Korn Ferry If

• You want executive search combined with assessment, pay and organization design.
• You need hiring support below the executive level as well as at the top.
• You want software and data tools for ongoing talent management.

Choose Spencer Stuart If

• Your priority is a director, chair or CEO appointment.
• You value a partner-owned firm focused on senior leadership.
• You want advice backed by long-running board governance research.

In either case, the individual partner leading your search matters most. Ask both firms for recent comparable appointments, their off-limits constraints and a clear fee proposal, and read executive search fees explained before you negotiate.
