The three conditions that make outsourcing the right call
Outsourcing execution works when three things are true: the work is defined enough to scope and brief, the volume or cadence exceeds what the in-house team can absorb, and the output doesn't require deep organisational context to be useful. Content production, paid media management, social media, and creative production all fit these conditions. Strategy, positioning, and anything that requires real-time decision-making about the business usually doesn't.
When to hire in-house instead
Hire in-house when the work requires deep embedding in the organisation: someone who attends the product meetings, hears the sales calls, absorbs the context that doesn't travel well through a brief. A growth marketer who needs to understand the product deeply enough to run experiments on it is probably a hire. A content operation that produces 12 assets a month from a structured brief probably isn't.
The false economy of doing it yourself
The most common alternative to outsourcing isn't an in-house hire — it's a founder or senior team member doing the work themselves. This is usually the most expensive option, because the opportunity cost of a senior person's time is the highest in the organisation. If a founder is spending six hours a week writing LinkedIn posts, the question isn't whether to outsource — it's how long the business can afford not to.
The transition question
Outsourcing execution is often a bridge, not a permanent state. A company that outsources content production while it's small might eventually hire a head of content who takes over. The relevant question isn't 'should we outsource forever?' — it's 'does outsourcing make sense for the next 12-18 months, given where we are?' If the answer is yes, the decision to outsource doesn't foreclose the in-house option later.
