Heidrick & Struggles review — search, leadership advisory & on-demand talent

Heidrick is strongest in Private Equity and CEO-acceleration work — it is one of the most active retained firms in PE portfolio company appointments, and the firm publishes 'Chief Executive Acceleration' as a named leadership advisory practice rather than just a search add-on. For a PE sponsor placing a portfolio-company CEO with a 100-day plan attached, Heidrick is regularly on the shortlist.

It is also a sensible choice when the brief sits at the intersection of search and leadership advisory — a CEO succession that comes with assessment of the wider executive team, a transformation that needs both a new functional leader and an organisation-design overlay. The firm's six published groupings are deliberately overlapping; you can buy search plus advisory from the same partner team.

And it is one of the few Big Five firms to publish a serious On-Demand Talent / interim practice. If you want interim leadership from a firm with the same brand and rigour as a retained search firm, Heidrick is one of the most obvious places to start the conversation.

The same Big-Five economics caveats apply: if your role is a £100–£150k VP-level functional hire, you will almost certainly get better value and faster delivery from a specialist boutique or an engaged-search model than from a Heidrick retained partner.

Heidrick's On-Demand Talent practice is real but it is a high-end interim brand sitting inside a Big Five firm — the cost structure reflects that. For straightforward fractional or interim engagements, a fractional platform with a focused candidate pool will typically be both faster and lower in total cost.

And if you are pre-Series A or earliest-stage scale-up, the Big Five economics simply do not fit your business model. Use a fractional executive to build the function and earn the right to a retained search once the role is at C-suite scale and a permanent appointment is the right answer.

Heidrick is the most explicit of the Big Five about the legitimacy of interim and on-demand senior work — its On-Demand Talent practice is a tacit acknowledgement that not every senior need is a permanent retained search. The same logic applies when choosing between a fractional platform and a Big Five engagement.

Fractional and interim executives are the right answer when the brief is defined-phase — bridging a permanent search, leading a transformation, running a function part-time during a scale-up phase, covering a vacancy. The economics of a fractional engagement (1–3 days a week, monthly invoice, no 30%+ search fee, start in 1–3 weeks) are aligned with that defined-phase shape; a retained search is aligned with the permanent multi-year appointment.

The honest test, if you are in the middle of the decision: 'in 18 months, do I expect this person to still be in seat in this same role with the same scope?' If yes, retained search. If no, fractional or interim.
