Direct answer
Use a contingency agency when you are filling a handful of critical sales seats and want $0 fixed recruiting cost until start, especially when that agency brings mock-call vetting you cannot replicate internally. Hire in-house revenue TA when you sustainably fill many AE or SDR seats per quarter and have a documented GTM playbook to source against. Fully loaded in-house TA often runs $150K to $250K+ per year before you place a single candidate.
When contingency agency support beats a full-time revenue recruiter, and when to hire TA in-house for GTM.
The crossover point for GTM hiring
If you will open one to three critical revenue seats after a raise, contingency usually wins on cash efficiency and vetting quality. A specialist sales recruiter with warm networks and an established mock-call vetting layer delivers faster, higher-quality finalists than an in-house generalist who is building those muscles from scratch.
If you are continuously hiring across SDR, AE, and sales leadership every month with a documented playbook, in-house TA plus selective agency overflow for specialist or executive searches becomes rational. The crossover is typically somewhere past 8 to 10 sales seats per year.
| Hiring volume | Default model | Why |
|---|---|---|
| 1–3 critical AE/SDR seats | Contingency agency | Pay on start, specialist networks, mock-call vetting |
| Ongoing monthly sales reqs | In-house TA | Always-on process and employer brand |
| Spike + baseline | Hybrid | Partner for spikes, TA for baseline fills |
Hidden costs both ways
Agency: fee percentage and coordination overhead. In-house: recruiter salary, sourcing tools, ramp time, and management bandwidth pulling founders away from deals.
Neither model fixes a broken interview loop or a role definition that shifts every two weeks. Fix your AE scorecard, your sales hiring criteria, and your offer timeline first, then choose your sourcing model.
