What a five-person team really costs — and what it buys
Let's be fair to the team. A five-person growth function does not just license tools; it provides judgement, coordination, and forty-plus collective hours a day of execution. The honest comparison is not 'tools vs people' — it is 'tools plus an agentic operator' vs 'people'.
Here is the trade laid bare, using mid-market Western European loaded costs:
| Line | Five-person team | Lean AI stack |
|---|---|---|
| People (5 × ~£5,500 loaded) | ~£27,500 / mo | £0 (founder + agents) |
| Core tool stack | included, often duplicated | ~£105 / mo (free at start) |
| Onboarding / ramp time | 1–3 months per hire | Hours |
| Coordination overhead | meetings, handoffs, management | None |
| Annual run-rate | ~£330,000 | ~£1,260 |
That is a 260-to-1 cost ratio at the extreme, and even if you halve the team to a more typical two-person setup the gap stays brutal. What the team buys you is throughput and specialist depth in any single discipline. What the lean stack buys you is range, speed of iteration, and a cost base low enough that the business is profitable on a fraction of the revenue.
The catalogue makes the deeper point clear. There are 50 distinct categories of growth and operations software in our grid — far more functions than five people could ever specialise in. A five-person team is forced to generalise across those fifty categories anyway; they simply cost two orders of magnitude more to do it. The tools were never the moat. The operating model is. If you want the discipline that decides which functions actually deserve attention first, the growth operating system is the frame, and choosing your one channel before spreading thin is covered in Choose the one channel that works.
