The fractional vs. full-time executive decision comes down to three factors: how much of the function you actually need, what you can afford, and how quickly the role will require full-time attention. For most companies under $20M ARR, fractional wins on all three.
The Core Decision Framework
Before choosing between fractional and full-time, answer these questions honestly: For more on this topic, see our guide on fractional CFO.
- Does this function require someone present in the business 5 days per week right now?
- Will the role need to manage more than 10 direct reports within 12 months?
- Is this a foundational hire that requires deep institutional knowledge built over years?
- Can you afford $200,000–$400,000 in total compensation without it straining your runway?
If you answered ‘yes’ to most of these, a full-time hire is probably right. If you answered ‘no’ to most, fractional is almost certainly the better option — at least for now.
When Fractional Wins
You’re Under $15M ARR
Below $15M ARR, the demand on most C-suite functions — finance, marketing, HR, operations — doesn’t justify a full-time executive. A fractional executive delivers 80–90% of the strategic value at 30–50% of the cost. The exception is functions with high day-to-day coordination requirements (like a full-time engineering lead).

You Need a Specific Skill Set for a Defined Period
Raising a Series B, launching into a new market, implementing a new ERP system — these are high-complexity, time-bound projects that benefit from specialist fractional leadership. Hiring full-time for a 6-month project is inefficient.
You’re Testing a New Function
Before you commit to a full-time CMO, bringing in a fractional CMO for 6 months tests both the market need and your organizational readiness. Many companies discover the function needs a different structure than originally assumed. For more on this topic, see our guide on fractional vs full-time CTO.
When Full-Time Wins
The Function Is Central to Daily Revenue Generation
A VP of Sales who runs daily pipeline reviews, coaches AEs, and manages a 15-person team needs to be full-time. A fractional sales leader who shows up 3 days per week loses deals and team coherence.
You’re Above $20M ARR and Scaling Fast
Above $20M ARR, most C-suite functions require full-time attention. The financial complexity, team size, and board oversight that come with scale demand an executive who is fully embedded. For more on this topic, see our guide on fractional executive vs consultant.
Culture and Long-Term Vision Matter
Fractional executives are skilled operators but they’re not building a career at your company. If you need someone who will carry institutional memory for a decade and shape company culture at a deep level, full-time is the right choice.
The Hybrid Path: Fractional Now, Full-Time Later
The most effective approach for growth-stage companies is to hire fractional now with a conversion option. You get immediate expertise, validate the function’s scope, and have a ready candidate for the full-time role if they perform. Many fractional executives convert to full-time after 12–18 months when the function demands it.

Frequently Asked Questions
At what company size should you switch from fractional to full-time executives?
The typical inflection point is $15M–$25M ARR for most C-suite functions. By that stage, financial complexity, team size, and board expectations usually demand full-time leadership. The exception is niche functions (CHRO, CIO, CRO) where fractional can scale further.
Can a fractional executive become a full-time hire?
Yes, and this is often the best outcome. A fractional executive who has spent 12–18 months learning your business, building your systems, and proving their value is a much lower-risk full-time hire than an external candidate. Many fractional engagements convert explicitly with this option built into the contract.
Is it cheaper in the long run to hire full-time instead of fractional?
Not typically, until you’re at a stage where the function requires 40+ hours per week of senior leadership. Below that threshold, fractional delivers a better cost-per-outcome. Above it, full-time is more efficient because fractional executives scale their rates as engagement intensifies.
