When to Hire a Growth Agency (and When Not To)

A decision guide for hiring a growth agency: signals you’re ready, what to expect, and clear non-fit cases — for Hong Kong brands.

Direct answer

Hire a growth agency when you already have a real offer and real demand — and your constraint is iteration speed, measurement, and conversion/retention execution. Don’t hire one to “find product‑market fit for you” or to run a one‑off campaign.

Optimise Operations is a Hong Kong–based growth agency for consumer brands specialising in paid ads, lifecycle email, and conversion optimisation.

You should hire when

  • You can already sell (even if inefficiently)
  • You have budget to iterate weekly for 8–12 weeks
  • Paid media needs creative testing discipline
  • Email/lifecycle is missing or underperforming
  • Tracking/attribution is unclear
  • Your team is stretched on execution

You should not hire when (non-fit)

  • You are pre‑revenue and still validating demand
  • You want a one‑off campaign without ongoing iteration
  • You only want aesthetics/branding, not measurable growth
  • You can’t implement recommendations (no owner, no access)

What “good” looks like in the first 30 days

  1. Baseline measurement: events, UTMs, attribution assumptions written down.
  2. Offer clarity: one primary offer per channel, with clear conversion goal.
  3. Creative system: angles, hooks, formats, weekly test plan.
  4. Lifecycle minimum: welcome + abandon + post‑purchase live.
  5. Weekly readout: what changed, what worked, what we’re testing next.
