Buyer context

The executive search buyer's question

What good looks like
Retained modelOne mandate at a time
Written processDiagnosis, sourcing, evaluation, integration
Board-adjacentReports to whoever owns the outcome
Post-hire accountabilityThrough the first 120 days

Most executive search firms will tell you the same three things: they have a global network, a rigorous process, and a strong reference list. All three claims are usually true. None of the three helps you decide which firm is the right one for a specific C-suite mandate at a specific company.

The buyer's question is narrower. Which of these firms has actually done this role, at this stage of company, in the last twelve to twenty-four months, and can walk me through how they did it? What follows is the evaluation framework that surfaces that answer.

Criteria

What to look for in an executive search firm

The six criteria above cut through most of the marketing. Ask the same six of every firm you meet and compare the answers side by side. Firms that struggle with any one of the six typically struggle with all six once you press.

  • Role-specific track recordAsk for anonymized examples of the exact role and the exact company stage in the last twelve to twenty-four months.
  • Written search processA retained firm should walk you through its diagnosis, sourcing, evaluation, and integration steps before the engagement letter is signed.
  • Real accountabilityThe firm owns the outcome through the first months after the hire starts, not through the placement handshake.
  • Board-communication postureAsk how the firm reports to the board or investor group; cadence, evidence, and slate structure are the signals.
  • Guarantee terms in writingA 90-day guarantee protects against immediate failure; the real failure window is longer. Understand the full re-run terms.
  • References from both sidesA strong firm can supply both the client who hired the placed executive and, with permission, the candidate who was placed.
Questions

8 questions to ask an executive search firm

Use these eight questions as your buyer script. Ask them in this order. The order matters because the first three questions filter for basic fit before the harder four surface.

  • 1. What is your track record on this specific role type at this stage of company? Ask for anonymized examples from the last twelve to twenty-four months.
  • 2. What is your search process, step by step? The answer should be a written framework you can share with the board.
  • 3. What are your guarantee terms, and what happens after ninety days? A short guarantee is a warning sign; the failure window is longer.
  • 4. May I speak with three clients and, with permission, two placed candidates? A firm that hesitates on the second half of that request is telling you something.
  • 5. Who runs this search day to day? The named partner in the sales meeting should be the named partner on the search.
  • 6. How do you handle competing candidates and blocked offers? The answer separates process discipline from wishful thinking.
  • 7. How do you report to the board or investor group? Cadence, evidence, and slate structure are the signals.
  • 8. What was your failure rate on the last twelve months of placements? A firm that cannot answer this has not been measuring the right thing.

If the answers to any three of those eight are evasive, the firm is not the right one. That is true regardless of brand.

Ask the same eight questions of every firm you meet. Answers you cannot compare side by side are not evaluations.
Model choice

Retained vs contingency: which model to choose

For a C-suite mandate the honest answer is retained. Retained search is engineered around the failure modes that produce senior-role hiring risk; contingency is engineered around volume. The two models are not two flavors of the same product. Our full comparison of the two models is on the retained vs contingency executive search page.

Red flags

Red flags when evaluating an executive search firm

The firm will not describe its process in writing. Every retained firm should be able to send you a one-page framework before the second meeting. Silence here means the process is improvised.

The firm cannot name a recent, comparable placement. Ask specifically for the same role type at the same stage of company in the last twelve to twenty-four months. A firm that answers with a global brand hire from five years ago is deflecting.

The firm will not connect you with a placed candidate. Client references are table stakes; candidate references are where the truth lives. A firm that treats candidate references as impossible is protecting something.

The firm proposes a compressed timeline as a differentiator. A promise to deliver a shortlist inside two weeks is a promise to skip the diagnosis phase. That is the exact compression that drives the failure rate up.

The lead partner in the sales meeting is not the lead partner on the search. This is the most common quiet failure mode. Confirm in writing who is doing the work.

Cost

How much does an executive search firm cost

Retained executive search fees are typically structured as a percentage of first-year total compensation, paid in installments at engagement, shortlist, and placement. The specific range varies with role, market, and firm. The full breakdown of how retained fees are built, what they cover, and how to evaluate them against the cost of a failed hire is on the executive search cost guide.

Timeline

How long does an executive search take

Advius runs C-suite searches on a 90-120 day baseline from mandate to signed offer. The clock covers the Clarity phase (diagnosis), the Precision phase (sourcing and evaluation), and the Momentum phase (offer, close, and the first 120 days). CEO searches sit at the longer end of the range, sometimes extending to 120-150 days when board alignment expands the Clarity and Momentum phases. Our executive search process and timeline page shows what happens week by week.

Signature

How Advius approaches executive search

Advius Group runs retained executive search exclusively. Every engagement is a single mandate, run through the Clarity, Precision, Momentum methodology, and supported through the first 120 days after the hire starts. The firm is built for growth-stage and PE-backed operators that need real accountability without the overhead of a global brand.

If the question in front of you is which firm to hire for a specific C-suite mandate, the shortest path to an answer is a scoping call. We will walk you through our written process, share anonymized examples from the last twelve months, and answer the eight questions above on the record.

Questions and answers

Frequently Asked Questions

What is an executive search firm?

An executive search firm is a professional-services firm engaged by a company or board to recruit senior leadership, typically at the C-suite and VP-with-P&L-scope level. The strongest firms operate on a retained model, run structured evaluation against role-specific success criteria, and stay accountable through the first months after the hire starts.

What do executive search firms do?

Executive search firms run four things: diagnosis (defining the role and its year-one and year-two success criteria), sourcing (direct outreach to a national candidate pool including passive candidates), evaluation (structured, criteria-referenced assessment), and integration (support through the first months after start). Everything else is process around those four.

How much do executive search firms charge?

Retained executive search fees are typically structured as a percentage of first-year total compensation, paid in installments across the engagement. The specific structure varies by role, market, and firm. Our executive search cost guide walks through how retained fees are built and what they cover.

What is a retained executive search firm?

A retained executive search firm is engaged exclusively for one search at a time, with fees paid in installments regardless of the outcome. The retainer funds the diagnosis, market mapping, and post-hire integration that contingency recruiting structurally cannot support. Retained is the standard model for C-suite and board-adjacent roles.

How do I choose the right executive search firm?

Compare three to five firms on the same criteria: track record on the specific role type and stage, written search process, references from both clients and placed candidates, guarantee terms, and board-communication posture. Evaluate on evidence rather than marketing.

Why use an executive search firm instead of my internal recruiter?

Internal recruiters are excellent at high-volume roles and active-candidate pools. Executive search firms exist to reach passive candidates at the C-suite level, run confidential outreach that the company cannot run on its own, and provide structured evaluation and post-hire integration for the highest-consequence hires. The two functions complement each other; they are not substitutes.

What is the difference between recruitment and executive search?

Recruitment typically means high-volume, active-candidate sourcing across many roles and clients at once. Executive search is single-mandate, passive-candidate-focused, retained-fee work at the C-suite and senior VP level. Different economic model, different candidate pool, different accountability.

What questions should I ask an executive search firm before signing?

Ask eight questions in order: track record on the specific role type; written search process; guarantee terms; references from clients and placed candidates; who runs the search day to day; how they handle competing candidates; how they report to the board or investor group; and what the failure rate is on their most recent twelve months of placements.
