Fractional Recruiting vs In-House Recruiter: Cost and Decision Guide
Fully loaded TA salary math versus Kas GTM retainers, plus when each model wins for Seed through Series B sales hiring.
(TL;DR) Summary
An in-house recruiter is a full-time employee on payroll. Fractional recruiting is an embedded external TA partner on a month-to-month retainer. For Seed through Series B GTM hiring, The Kas Group fractional bands are $5,000/mo (up to 2 Seed/A roles) or $8,000/mo (up to 5 GTM roles) with zero success fees. A solid in-house TA seat often runs $100k-$160k+ fully loaded once you add salary, benefits, LinkedIn Recruiter, and tools. Fractional wins when hiring is bursty and sales-specialist quality matters. In-house wins when you need sustained, cross-function volume (roughly 10+ hires per quarter) and full internal ownership. Many teams run fractional now, then hire in-house later and keep a specialist for GTM.
What is fractional recruiting vs a full-time in-house TA recruiter?
Fractional recruiting
You pay a fixed monthly retainer. A recruiting partner embeds with founders and hiring managers, owns pipeline and close, and pauses when the seats are filled. At Kas, fractional is sales/GTM focused and month-to-month. Full model: fractional recruiting guide. Product page: fractional sales recruiting.
Full-time in-house TA
You hire a recruiter onto payroll. They own your ATS, employer brand, and ongoing reqs across functions. You get full internal ownership. You also carry salary, benefits, tools, and under-utilization risk when hiring slows.
| Dimension | Fractional recruiting | In-house TA recruiter |
|---|---|---|
| Relationship | External partner, embedded bandwidth | Full-time employee |
| How you pay | Monthly retainer | Salary + benefits + tools |
| Flex | Turn on/off month to month | Headcount (harder to pause) |
| Typical depth | Specialist (Kas: sales/GTM) | Generalist unless you hire two |
| Best fit | Bursty Seed-B GTM hiring | Sustained, multi-function volume |

How much does an in-house recruiter cost vs Kas fractional retainers?
Fully loaded in-house TA cost (worked annual math)
Use ranges, not a single myth number. A credible first recruiter package for a startup often lands here:
| Cost line | Low | Mid | High |
|---|---|---|---|
| Base salary | $85,000 | $110,000 | $130,000 |
| Benefits / taxes / payroll load (~25-35%) | $21,000 | $33,000 | $45,000 |
| LinkedIn Recruiter + job boards | $8,000 | $12,000 | $15,000 |
| ATS / scheduling / misc tools | $2,000 | $4,000 | $6,000 |
| Fully loaded annual | ~$116,000 | ~$159,000 | ~$196,000 |
| Approx. monthly | ~$9,700 | ~$13,250 | ~$16,300 |
So a mid-range in-house seat is about $100k-$160k fully loaded for many Seed-B teams. Add 60-90 days of ramp before the seat is fully productive on your motion.
Kas fractional retainers (sales / GTM)
| Tier | Monthly fee | Capacity | Success fees |
|---|---|---|---|
| Tier 1 | $5,000/mo | Up to 2 Seed / Series A roles | Zero |
| Tier 2 | $8,000/mo | Up to 5 GTM roles | Zero |
Flat success-fee alternative (if you prefer per-hire instead of retainer): SDR $5,000 · AE $7,500 · Senior AE / Sales Manager $10,000. Director / VP / CRO searches are specialist or retained quote only.
Side-by-side annual math (worked examples)
Scenario A: 6 months of GTM hiring, then a pause
| Path | Math | You pay |
|---|---|---|
| In-house (mid fully loaded) | $13,250 x 12 (you still carry the seat after the pause) | ~$159,000 / year |
| Kas Tier 1 x 6 months | $5,000 x 6 | $30,000 |
| Kas Tier 2 x 6 months | $8,000 x 6 | $48,000 |
Fractional is built for the pause. In-house keeps burning after the pod is full.
Scenario B: Steady GTM hiring for 12 months (2-5 seats in flight)
| Path | Math | You pay |
|---|---|---|
| In-house (mid) | Fully loaded year | ~$159,000 |
| Kas Tier 1 x 12 | $5,000 x 12 (up to 2 Seed/A roles) | $60,000 |
| Kas Tier 2 x 12 | $8,000 x 12 (up to 5 GTM roles) | $96,000 |
Even at full-year Tier 2, Kas fractional is usually well below a mid fully loaded in-house seat. The tradeoff is ownership and cross-function coverage, not just cash.
Scenario C: High volume across functions
If you need 10+ hires per quarter across eng, GTM, and ops, one fractional GTM retainer will not replace a full TA function. That is when in-house (or in-house plus specialist) wins.
When does fractional recruiting win?
Fractional wins for sales/GTM when:
- You are Seed, Series A, or early Series B and hiring is real but not a permanent department yet.
- Hiring is bursty (raise, then fill a pod, then pause).
- You need a sales-specialist bar (quota history, ACV, cycle length, outbound vs inbound), not a generalist who also runs ops and marketing reqs.
- You want predictable monthly spend you can turn off.
- Cash matters and you refuse carrying a $100k-$160k seat through a quiet quarter.
On Kas AE / SDR / Sales Manager searches under fractional, you also get a free market scan in 48-72 hours and a search target of 3+ qualified candidates in 3 weeks (or we keep hunting). Those speed claims apply to AE/SDR/SM under fractional, not to Director/VP/CRO leadership searches.
When does hiring an in-house recruiter win?
In-house wins when:
- You have sustained high volume across functions, not just GTM sprints.
- You are consistently at roughly 10+ hires per quarter.
- You need full internal ownership of ATS, employer brand, recruiting ops, and cross-team coordination.
- Recruiting is a permanent department with a clear manager and roadmap.
- Under-utilization risk is low because the req list never really empties.
An in-house generalist is rarely the best solo answer for elite AE or VP Sales calibration. Many teams that hire internal TA still keep a GTM specialist for the seats that move ARR.
Hybrid path: fractional now, in-house later
You do not have to pick forever on day one.
- Now (Seed-A / early B): Run fractional sales recruiting to fill AE/SDR/SM seats with specialist bandwidth.
- Later (sustained volume): Hire your first in-house recruiter when cross-function volume justifies a full seat.
- Keep the specialist: Leave hard GTM seats with a partner who already knows your ICP, pitch, and bar.
Fractional covers the learning curve. In-house takes over always-on ops. Specialist search stays where a wrong hire is a six-figure mistake.

Use this as a yes/no scorecard.
| Question | If yes, lean |
|---|---|
| Are we Seed through early Series B with 1-5 GTM seats ahead? | Fractional |
| Is hiring bursty (sprint, then quiet)? | Fractional |
| Do we need a sales-specialist bar more than a generalist TA? | Fractional |
| Can we pause spend when the pod is full? | Fractional |
| Are we at ~10+ hires/quarter across multiple functions? | In-house |
| Do we need full internal ATS / brand / ops ownership? | In-house |
| Is recruiting a permanent department, not a sprint? | In-house |
| Do we want both volume coverage and elite GTM depth? | Hybrid (in-house + specialist) |
Quick rule: If recruiting is still a sprint, buy fractional. If recruiting is a department, hire in-house. If GTM quality still matters after you hire internal TA, keep the specialist.
