Hire a VP Sales when you have a repeatable sales motion for them to scale. Use fractional BD when that motion still needs to be designed — typically seed through Series B, where founder-led sales has hit a ceiling. A VP hired before the motion exists spends a year discovering it at full-time cost, and healthcare buying cycles mean you find out too late.
The failure mode this question is really about.
The expensive mistake is not choosing the wrong option. It is hiring a VP Sales to find the motion instead of to scale it. In healthcare, sales cycles run long enough that a mis-hire takes a year to surface. By then you have paid a full-time executive package to learn what a scoped engagement would have told you in a quarter.
When the VP Sales hire is right.
- You have closed repeatable deals with a motion someone else could run — the ICP, the champion profile, and the procurement path are written down, not in the founder's head.
- Pipeline coverage justifies a full-time leader and the hires under them.
- You can define the role by scale-up metrics (quota, ramp, coverage), not discovery questions.
When fractional BD is right.
- Founder-led sales hit a ceiling — the classic Series A/B shape, where deals close only when a founder runs them.
- Pre-revenue — often the best time, because ICP, positioning, and procurement design are cheapest to fix before the first contract hardens them.
- The buyer is the hard part — IDNs, health plans, post-acute, value-based care. Category scar tissue matters more than headcount.
They also coexist.
Having a VP Sales does not rule out outside help. The common pattern is a VP who wants senior support on a specific buyer or procurement cycle — a deal sprint or RevOps project that runs alongside the VP, not over them. Anything that undercuts your VP is the wrong engagement.
The cost logic.
Fractional BD prices under one VP Sales hire, and the downside is capped: a fractional engagement with a 30-day exit costs you a month to unwind; a wrong VP hire costs a year and the pipeline that stalled with it. Sequence accordingly — design the motion first, then hire the person to scale it.
