Retained search dominates. Equity negotiation can extend close timeline by 2-3 weeks. Internal promotion is meaningfully cheaper and shows lower year-one attrition.

Rarest profile. Most candidates are passive; reference network is the channel. Specialist retained-search firms typical. RSU dilution often dominates package conversation.

Notes on figures

Caveats and data sourcing

  • Recruiter-fee ranges are widely cited industry norms (SHRM Talent Acquisition Benchmark, Robert Half hiring guides). Specific firms are not named.
  • Salary bands reflect US-market mid-range for 2026. Adjust upward 10-25% for SF / NYC and downward 10-20% for cost-of-living-adjusted markets.
  • Bad-hire risk (not included in line items above) sits at 30-60% of first-year salary per DOL and BLS-cited turnover-cost studies.
