Fractional, interim or consultant: which senior marketing help do you need?
Fractional, interim and consultant sound similar but solve different problems. A clear guide to which type of senior marketing help fits your situation.

Three terms, three different problems
“Fractional”, “interim” and “consultant” get used interchangeably, but they solve genuinely different problems. Choosing the wrong one wastes money and time, so it’s worth being precise about what each is for.
Consultant — advice and a plan
A consultant diagnoses a problem and recommends what to do, usually within a defined scope and timeframe, and typically doesn’t own the execution or the outcome. Best when you need expert thinking, a strategy or an audit, and you have the team to deliver it. The limit: advice without ownership only helps if someone internal drives it.
Interim — full-time, temporary
An interim leader steps in more or less full-time for a fixed period — covering a gap (a departure, a parental leave) or leading through a specific phase (a transformation, a fundraise). Best when you need dedicated, full-time senior leadership right now but not permanently. The trade-off is cost close to full-time for the duration.
Fractional — part-time, ongoing ownership
A fractional leader works part-time on an ongoing basis, owning strategy and delivery and accountable for the number — the “missing middle” between a consultant’s advice and an interim/full-time hire’s hours. Best when you need senior ownership and continuity, but not full-time presence — the common scale-up situation. (Full detail in the fractional CMO playbook.)
Which do you need?
- Need a plan or an expert view, with a team to execute it → consultant.
- Need full-time leadership for a fixed period or to cover a gap → interim.
- Need ongoing senior ownership of growth without a full-time hire → fractional.
Some situations blend them — a diagnostic (consultant-style) that becomes an ongoing fractional engagement is common, and a fractional role can flex toward interim during an intense phase.
Frequently asked questions
What’s the difference between fractional and interim?
Interim is full-time for a fixed period; fractional is part-time on an ongoing basis. Different hours, different purpose.
Is a consultant the same as a fractional CMO?
No — a consultant advises within a scope; a fractional CMO owns strategy and delivery and is accountable for the number.
Can one person play more than one role?
Often — e.g. a diagnostic that becomes a fractional engagement, or a fractional role that flexes to interim during a big push.
