A framework for SaaS founders weighing a six-month fractional engagement against a $250K+ full-time VP hire. The decision tree we walk founders through in discovery.
The decision usually arrives at one of three moments
Founders don't sit down on a Tuesday and decide it's fractional-vs-full-time day. The decision usually shows up wrapped in one of three other decisions:
- Post-raise. You closed a round, your investors want a credible post-sale function, your board materials are due in six weeks, and there is no path to having a real VP of CS in seat by then.
- Mid-flight. Your current CS leader has resigned, your last hire didn't work, or you've been running CS yourself and the wheels are starting to wobble.
- Crossing $5M ARR. You've outgrown a CS leader who was great at $3M but is clearly out of depth at $7M, and you can feel the next hire needs to be different.
In each case, the choice between fractional and full-time isn't really "consultant or employee." It's "which one solves the actual problem you have right now."
Three questions that decide it
We walk founders through this on the discovery call. It clarifies the choice surprisingly fast.
1. Is the problem definable?
If you can say in two sentences what you need this person to do ("build the onboarding playbook and the health score") fractional is almost always the right answer. Fractional is best when the work is defined and execution-heavy.
If you genuinely don't know what the problem is yet ("retention is bad and I'm not sure why"), you don't need a leader yet at all. You need a Health Check or scoping engagement first. Hiring a full-time VP to figure out the problem is a $300K diagnosis.
2. How load-bearing is this role in the next 6 months?
If you're presenting to the board in 90 days and need a credible operating model in place, you don't have time for a full-time hire. Even a fast hire from a great executive recruiter is a 4-month search plus a 3-month ramp. That's seven months. Fractional gives you a senior operator in your team in two weeks.
If, on the other hand, this is your CS leader for the next three years (a defining hire that will compound) then you need full-time. The fractional model is bad at long compounding because the operator is part-time by design.
3. Can you actually afford the full-time hire?
The all-in cost of a VP of CS at a growth-stage B2B SaaS company in 2026 is between $260K and $400K. That includes salary, equity (heavily discounted to cash-equivalent), benefits, and the on-target bonus. Plus the recruiter fee (~25% of base) for the search.
A fractional engagement is $8K–$15K per month, no equity, no benefits, no recruiter fee, no severance risk. That's $48K–$90K for a six-month engagement.
If the answer to "can you afford the full-time hire" is "yes, but only barely, and it leaves me no buffer," fractional buys you the runway to make the right full-time hire later, with the function already partway built.
The compound move
The strongest move we see, and the one we recommend most often, is both. Fractional first, then full-time, with the fractional operator helping recruit and onboard the full-time hire.
In that model:
- The fractional operator builds the function so the full-time hire walks into something defined, not a blank canvas.
- The fractional operator helps write the JD, screens candidates, and participates in the loop.
- The full-time hire shadows the fractional operator for 4–6 weeks before taking over.
- The fractional operator transitions to advisory once the full-time hire is up.
We've run this play maybe a dozen times. It consistently produces full-time hires that stick, usually because the founder, with a senior operator at their side, made a sharper hiring decision than they would have rushing it alone.
What it doesn't fix
Fractional doesn't fix a broken product. Doesn't fix a sales motion that's selling the wrong customer. Doesn't fix a churn problem rooted in pricing.
If your post-sale function is the second-order symptom of a first-order problem somewhere else in the business, hiring anybody to lead CS (fractional or full-time) is treating the bruise instead of the broken bone. The Health Check is designed to surface exactly that distinction before you hire.
If you're standing at this decision, get on a call. We'll tell you which one solves your actual problem, even if the answer is neither.
