Fractional executive vs agency vs consultant
A fractional executive owns strategy and people. An agency executes tactics at scale under a strategy. A consultant delivers a defined project. Most companies use two of the three at once — fractional for direction, agency for execution.

| Executes at scale? | No | Yes | Sometimes |
| Hires your team? | Yes | No | No |
| Reports to CEO / board? | Yes | No | Sometimes |
| Duration | 6–18 months | Ongoing retainer | 4–12 weeks |
| Cost (US, 2026) | $6K–$20K / mo | $5K–$50K / mo | $50K–$300K / project |
| Best for | Missing leader | Scaled execution | Defined study or build |
When to hire a fractional executive
The function is missing a leader. Someone needs to set direction, hire the team, own the number, and report to the board. Agencies and consultants cannot fill this role — neither has authority to hire or fire, and neither carries board accountability.
When to hire an agency
Strategy is set. You need scaled execution — paid media, creative production, SEO, content, or engineering staff augmentation. Agencies are best briefed by a fractional executive or in-house lead. Agencies without a briefer produce polished output aimed at the wrong target.
When to hire a consultant
The deliverable is defined and finite. Market entry study, pricing overhaul, org design, M&A model, system implementation. Consultants shine when the question is 'what should we do?' rather than 'do it.'
The common hybrid
The most common Series A configuration: fractional CMO ($10K/mo) plus a specialist paid-media agency ($10K/mo) plus one in-house marketer ($10K/mo fully loaded). Total: $30K/mo for a full marketing function. Same math applies to product (fractional CPO + dev agency + one PM) and engineering (fractional CTO + contractor team + first FT engineer).

FAQs
Can a fractional CMO replace both agency and consultant?
For strategy and small-team execution: yes. For scaled paid, creative, or SEO: no. Combine fractional (direction) with agency (execution).
Which do I hire first?
Fractional executive. Strategy before execution. Agencies and consultants both execute better under a briefer.
