Spencer Stuart review — board, CEO succession & leadership consulting

Spencer Stuart's reputation sits squarely in board and CEO work. CEO Succession Planning is one of the firm's nine published capabilities and the practice it markets most prominently. For a FTSE 100 or S&P 500 board running a long-range CEO succession, or for a nomination committee searching for a new non-executive director or chair, Spencer Stuart is on the shortlist of firms most boards will at least take a meeting with.

It is also the firm most clients reach for when the search is identity-defining and the appointment has to be right rather than fast. The retainer model, the depth of research investment, the three-month-plus timeline and the senior-partner involvement all line up with the high-stakes appointment, not the routine one.

Sector-wise, Spencer Stuart publishes practices across eight industry groupings (above). It is particularly well-known in Financial Services, Industrial, Consumer and TMT — broadly the FTSE 100 / S&P 500 universe — and has built out a substantial Private Equity practice over the last decade.

If you are an early-stage or growth-stage company looking for your first commercial CFO, your first Head of Engineering, or a one-person marketing leader, the cost and timeline of a Big Five retained search will be out of proportion to the role. Spencer Stuart genuinely is built for the £200k–£600k+ permanent appointment; running a £120k VP search through a Big Five partner is a category mismatch on both sides.

It is also the wrong tool when you need senior capability quickly — a board has changed and you need a new CFO in week three, an existing executive has resigned and you need cover while you do the proper search, you are bridging a fundraise and need someone who can run finance for six months. A retained search will not start with a candidate in seat for 3–6 months from briefing.

And it is the wrong tool when you are not yet sure you need a full-time hire at all. A common pattern at Series A / Series B is the founder convincing themselves they need a permanent CMO when what they actually need is two days a week of senior marketing direction for the next nine months. A retained search forces the full-time decision before the evidence is in.

Fractional and interim executives sit in the gap a Big Five retained search cannot economically fill — defined-phase senior capability that doesn't justify the £60–£200k+ search fee, the 3–6 month timeline, or a permanent annualised package.

Typical patterns where fractional fits and Spencer Stuart doesn't: a Series A founder needing first-time finance discipline at one to two days a week; an interim CFO covering a permanent search or bridging a fundraise; a fractional CMO building the function before a permanent hire; an interim chair through a turnaround; an interim CTO during a platform replatform. None of these require the depth of CEO-succession research; all of them benefit from starting in week 2 rather than month 4.

Fractional and retained search are not substitutes — they answer different questions. The right discipline is to ask 'is this a permanent multi-year identity-defining appointment?' If yes, pay for a retained search. If no, a fractional or interim executive will give you better economics and a faster start.
