When fractional beats full-time
Fractional is the right call when: (1) the role does not yet need 40 hours of senior attention, (2) the company needs a playbook installed before hiring full-time, (3) the founder is unsure what they actually need in the role, or (4) the problem is time-bound (a fundraise, a pivot, a turnaround).
When full-time beats fractional
Full-time wins when: (1) the role requires constant daily presence (sales leadership at scale, head of engineering with a live team), (2) the company is past $20M ARR and the function has 10+ reports, or (3) the executive will be the culture-carrier of the function long-term.
The hybrid model most companies end up with
The dominant pattern now is: hire a fractional to install the function, then hire full-time from inside the fractional's network once the playbook is working. This cuts 12 months off the typical "we hired too early" mistake.
