Fractional Recruiting for Startups: When It Beats Agency and In-House
Buyer guide for Seed-Series B: Kas fractional retainers, fee math vs contingency, and when to stay on flat success fees.
(TL;DR) Summary
Fractional recruiting is a month-to-month retainer where an external recruiting partner acts as your embedded TA lead, without a full-time hire. For Seed-Series B startups, The Kas Group prices fractional sales/GTM recruiting at $5,000/mo (up to 2 Seed/Series A roles) or $8,000/mo (up to 5 scaling GTM roles) with zero success fees. That is usually cheaper than stacking 20-30% contingency invoices on AE packages, and sharper than a generalist agency that treats sales seats like any other req. Kas also runs AI/ML recruiting under the same roof. Fee math detail: fractional sales recruiting vs contingency.
What is fractional recruiting vs agency vs in-house TA?
| Model | What it is | You pay | Commitment |
|---|---|---|---|
| Fractional recruiting | Embedded part-time recruiting partner who owns pipeline, calibration, and close | Monthly retainer | Month-to-month (Kas: on/off flex) |
| Contingency agency | Non-exclusive firms race to submit candidates | 20-30% of first-year cash/OTE per hire | Per placement |
| Retained / project search | Exclusive deep search for one senior seat | Project or milestone fees | Per search |
| In-house TA | Full-time recruiter on payroll | Salary + benefits + tools (~$100k-$160k+ fully loaded) | Ongoing headcount |
Fractional is not a hiring marketplace. It is not an ATS. It is a senior operator embedded with your founders and hiring managers. Sales-specific product: fractional sales recruiting.

Is fractional recruiting right for Seed, Series A, and Series B?
| Stage | Hiring pattern | Fractional fit |
|---|---|---|
| Seed | First AE, maybe SDR; founder still closes | Strong. Tier 1 beats paying 25% on your first AE. |
| Series A | AE pod + SDR; first Sales Manager questions | Strong. Tier 1 to Tier 2 as volume rises. |
| Series B | Multiple GTM seats; possible first VP Sales | Strong for ongoing GTM. Pair VP with a dedicated specialist/retained process. |
| Later / high volume | 10+ hires/quarter across functions | Consider in-house TA; keep specialist search for GTM + AI/ML. |
For first VP Sales questions, see who to hire: VP Sales for a startup.
Fractional beats contingency when
- You will open 2+ specialized seats in a quarter
- Roles are GTM or technical (not commodity backfills)
- You want one partner who learns your ICP, pitch, and bar, then reuses that context
- Cash is real but you refuse OTE-percentage invoices on $150k-$350k packages
Stay on contingency / flat success fee when
- Exactly one clear backfill and no pipeline of follow-on seats
- The JD is stable and the market is liquid
- Seat is SDR/AE/Sales Manager and flat fee pricing fits better than a retainer
Why Kas vs a generalist fractional or marketplace shop
Most "fractional recruiting for startups" content is written for generic TA: post jobs, run loops, fill mixed reqs. Fine for ops. Thin for the seats that move ARR.
- Elite B2B SaaS sales / GTM recruiting : SDRs through VP Sales, scorecards built on quota, ACV, and motion fit. Product: fractional sales.
- AI/ML recruiting under the same roof : Kas also does AI/ML recruiting so your Series A hiring sprint does not require three vendors. Product: AI recruiting.
- Transparent GTM pricing : $5k / $8k retainers or $5k-$10k flat success fees through Sales Manager. Not 20-30% surprise math. Director/VP/CRO: quote only.

How we run work: methodology. Avoid framing this as an ATS or marketplace problem. If your bottleneck is "we need a senior sales desk + technical bar," buy that, not software seats.
What does a fractional engagement look like week to week?
Week 0-1: Calibration
Scorecards, comp bands, ICP, must-have vs nice-to-have. For AE/SDR/Sales Manager seats under fractional, a free market scan lands in 48-72 hours.
Weeks 1-3: Pipeline
Direct outreach to passive operators. For AE/SDR/SM under fractional: target 3+ qualified candidates in 3 weeks. Director/VP/CRO searches use a dedicated specialist process.
Ongoing: Loops and close
Interview design, debriefs, offer strategy, counter-offer defense.
Month boundary: Keep or pause
Month-to-month. Scale to Tier 2 when you add seats. Pause when the pod is full.
You get dedicated bandwidth. You do not get resume spam from five non-exclusive desks.
Fractional vs hiring your first in-house recruiter
| Fractional (Kas Tier 1-2) | First in-house recruiter | |
|---|---|---|
| Cash outlay | $5k-$8k / mo | ~$8k-$13k / mo fully loaded + tools |
| Ramp | Days (specialist already knows GTM/AI) | 60-90 days to learn your motion |
| Flex | Cancel month-to-month | Severance / awkward under-utilization |
| Depth on sales + AI/ML | Built-in GTM specialist; Kas also runs AI/ML recruiting | Generalist unless you hire two |
Rule of thumb: if you do not yet have sustained hiring volume across many functions, fractional usually wins. Hire in-house TA when recruiting is a permanent department, not a sprint.
FAQ: fractional recruiting for startups
What is fractional recruiting in plain English?
You pay a monthly retainer for an embedded recruiting partner who runs your searches part-time as if they were your TA lead. At Kas, fractional sales/GTM retainers are $5,000 or $8,000 per month with zero success fees.
How is fractional different from a recruiting agency?
Agencies (especially contingency) get paid per hire, often 20-30% of comp, and may work your role non-exclusively. Fractional is exclusive bandwidth on a retainer. Incentives skew to quality of process, not submission volume.
When should a Seed startup use fractional recruiting?
When you are hiring your first AE/SDR pair, or any specialized seat where a 25% fee on OTE hurts and you want a partner who understands SaaS GTM. Tier 1 ($5,000/mo, up to 2 roles) is built for that stage.
Can fractional cover AI/ML roles too?
Yes in the Kas model. Sales/GTM fractional is the retainer product; Kas also runs AI/ML recruiting. Ask [email protected] how to sequence GTM and technical seats in one plan.
Is there a long contract?
No. Kas fractional is month-to-month. Turn it off when hiring pauses.
Fractional or flat success fee, which should I pick?
Flat success fee (SDR $5,000 / AE $7,500 / Senior AE or Sales Manager $10,000) for a single clear seat through Sales Manager. Director, VP, and CRO seats are specialist/retained quote only. Fractional when you have multiple GTM seats or need ongoing embedded search. Fee math: retained vs contingency recruiting.
