The in-house versus agency decision is the choice between hiring marketing employees or engaging an external partner. The trade-off involves total cost, speed to capability, breadth of skills, and management overhead. The right answer depends on whether you need one skill deeply or several skills at once.

The comparison founders usually make is salary versus retainer, and it is the wrong one. A hire costs salary plus benefits plus tools plus your time managing them, plus the months before they are productive, plus the risk they are wrong. An agency costs the fee. The real question is not which is cheaper but whether you need one specialist or an entire function.

Example:

Hiring one marketer gives you one skill set. Marketing needs strategy, content, paid, design, and analytics. One hire cannot be all five, which is the actual reason the first marketing hire so often disappoints.

What is the true cost of a marketing hire?

Salary plus benefits, tools, recruitment cost, the founder's management time, and the ramp period before they produce results. The salary figure alone understates it substantially.

When does hiring in-house make more sense?

When you need one capability deeply and continuously, and you have the management capacity to direct it. When you need a full function, one hire cannot cover it.
