Build vs Hire Sales Capacity: The Cash Runway Impact Most CFOs Miss

The Economic Decision

CFOs and founders evaluating a sales capacity expansion almost always anchor on per-seat cost. That is the wrong lens. The right lens is cash runway: how many months of operating runway does this hiring decision consume, and does the pipeline it produces extend runway by more than it consumes?

For most growth-stage B2B companies in Europe, building a 3-person SDR team in year one consumes €270K–€360K of cash. Rented capacity producing 85–95% of the pipeline output consumes €90K–€165K. The gap — €105K–€270K — is 5–9 months of extra runway you keep by renting first.

The Cost Comparison: Runway-Adjusted

Built team (3 SDRs, Western Europe): €90K–€120K per seat fully loaded × 3 = €270K–€360K in year one. Add ramp drag (3–4 months × 3 seats × ~50% productivity loss) and the realised cash-to-pipeline ratio is even worse than the headline.

Rented team (3 pre-vetted remote SDRs): €30K–€55K per seat × 3 = €90K–€165K, no recruiter fees, no notice-period overhang, no severance risk. Pipeline output lands at 85–95% of the built equivalent because vetting and ramp time are compressed. See [what does a remote SDR cost in Europe](/blog/what-does-remote-sdr-cost-europe) for the per-seat breakdown.

When Building Makes Sense for Cash Runway

Building makes runway sense when: ACV is high (€30K+) and one closed deal funds 6–12 months of seat cost, sales-cycle length matches your runway horizon, and you have 18+ months of cash buffer to absorb the ramp drag.

Below those thresholds, building consumes runway faster than it produces pipeline. Validate against [pipeline required to justify a new sales hire](/blog/pipeline-required-justify-new-sales-hire-cost) and [revenue threshold for hiring your first SDR](/blog/revenue-threshold-hiring-first-sdr-cost).

When Renting Protects Runway

Renting protects runway when: cash is constrained, outbound is unproven, ACV is below €30K, or you cannot afford a 3–4 month ramp before the first qualified meeting lands. The flexibility to scale up or down quarterly is a runway-preservation tool, not just a cost-control tool.

The Hidden Runway Cost: Recruiter Retainers

Recruiter fees of 15–25% of first-year salary add €8K–€20K per seat to the build path — paid in the same quarter as the hire, before any pipeline lands. For a 3-person build, that is €24K–€60K of front-loaded cash burn that the rented path does not carry.

What to Do Next

Run the runway calculation before the headcount calculation. Take expected sales-capacity spend, divide by current monthly burn, and you have the runway-impact number that should drive the build-vs-rent decision.

If the runway gap is significant and the pipeline economics are still being validated, rent first. [Request matched profiles](/signup/company), or compare on [build in-house SDR team vs hire remote talent](/blog/build-in-house-sdr-team-vs-hire-remote-talent).
