In-house vs agency

Hire a marketer, or hire a whole team.

For an 11 to 100 person company, this is the real decision: one in-house generalist who can't cover every channel, or a senior team that can — for less than a couple of salaries. Here's the honest math.

Let's talk

What does one in-house marketer actually cover?

Modern marketing is at least five distinct disciplines: SEO, paid ads, content, web, and analytics. A strong generalist can own one or two of them at a senior level and manage the rest. The channels they're weakest in quietly underperform — and that gap is the real cost of a single hire.

The lone generalist

One salary, one calendar, one skill ceiling. Broad enough to keep the lights on, rarely deep enough to win on every channel at once.

The full specialist bench

Five senior hires covers the breadth — and the payroll, benefits, tools, and management that come with it. Few companies under 100 people can justify that.

The practical middle

A fractional, full-service partner gives you senior coverage across the whole stack at a fraction of a multi-hire team, with one person accountable.

How does the math actually work out?

A single mid-level marketing hire typically runs a full salary plus benefits, payroll tax, software, and weeks of ramp before anything ships. Covering every channel in-house means stacking several of those salaries. A full-service retainer covers the same breadth for the cost of running the operation, not the headcount.

The in-house bill

  • Base salary for each specialist you need
  • Benefits, payroll tax, and equipment on top
  • Software and tool licenses, per seat
  • Weeks of hiring and ramp before output
  • Coverage gaps on vacation, sick days, and turnover

The Spec retainer

  • Every channel run as one operation
  • Tools, seniority, and management included
  • From $2,500/mo, with the full price up front
  • Month to month
  • You own every account and dataset

Salary figures vary widely by role, seniority, and market — treat any you see as general ranges, not quotes. The point isn't a precise number; it's that one hire can't cover the full stack, and a full bench costs far more than a focused retainer.

Side by side, honestly.

Each model wins on something. The right call depends on how much breadth you need and how much overhead you can carry.

Channel breadth
In-house — One generalist can't be senior at SEO, ads, content, web, and analytics at once.
Agency — Broad, but often staffed with juniors behind a polished account manager.
Spec — Every channel run as one operation, accountable to one person you talk to.
Cost
In-house — Salary, benefits, payroll tax, tools, and ramp time before any output ships.
Agency — Retainer plus frequent upsells, with pricing you only see on a call.
Spec — Retainers from $2,500/mo, month to month. Tools and seniority included.
Speed to output
In-house — Weeks to hire, then weeks more to ramp on your business and stack.
Agency — Faster, but slowed by approval chains and shared account-manager attention.
Spec — AI-accelerated execution means work ships in days, not quarters.
Risk
In-house — One person. If they leave, the knowledge and momentum leave with them.
Agency — Account-manager layers, hidden pricing, and your data often held inside their accounts.
Spec — Month to month, prices up front, and you own every account and dataset.
Coverage gaps
In-house — Vacations, sick days, and skill blind spots leave channels dark.
Agency — Covered, but you pay for layers of overhead to get there.
Spec — One system covers the full stack continuously, with no single point of failure.

In-house or agency, answered straight.

Is it cheaper to hire in-house or use a marketing agency?

It depends on breadth. One in-house generalist is cheaper than a full agency, but cannot cover SEO, ads, content, web, and analytics at a senior level. To match an agency's breadth in-house, you'd hire several specialists — usually well beyond a single salary.

Can one in-house marketer do everything?

Rarely. SEO, paid ads, content, web development, and analytics are distinct disciplines. A capable generalist can manage one or two well and dabble in the rest. The channels they're weakest in quietly underperform, which is the hidden cost of a single hire.

What is a fractional marketing team?

A fractional team gives you senior coverage across every channel without a full-time payroll for each. You get the breadth of an agency and the accountability of a hire, paying only for the operation rather than for headcount, benefits, and ramp time.

How is Spec different from a traditional agency?

Spec runs marketing as one AI-fulfilled operation instead of stacking account managers and junior staff. Pricing is published, billing is month to month, and you own your accounts and data. One person stays accountable for the whole machine.

Should an 11 to 100 employee company hire in-house or outsource?

At that size, most companies need more breadth than one hire delivers but less overhead than a large agency demands. A fractional, full-service partner is usually the practical middle path: senior coverage on every channel for less than a couple of salaries.

Do I keep ownership of my marketing accounts?

With Spec, yes. Your ad accounts, analytics, website, and data stay in your name. If you ever leave, you keep everything. Many agencies hold these inside their own accounts, which makes switching costly and is worth checking before you sign.
