How to build an AI stack for a five-person team without wasting budget

A practical sequence for adopting AI tools: one assistant, one automation layer, one specialist tool per bottleneck.

Key takeaways

  • One assistant licence per person beats five half-used specialist tools.
  • Automation pays off only after a process repeats at least weekly.
  • Buy specialist tools against a measured bottleneck, never a demo.
  • Review the stack quarterly and cancel anything below 30% seat usage.

Layer one: a single assistant

Give everyone the same assistant before buying anything else. A shared tool creates shared vocabulary, shared prompt libraries and a realistic baseline of what AI can already do in your context.

At roughly $20 per seat, this is the cheapest experiment available and it surfaces the real bottlenecks worth automating.

Layer two: automation once the pattern repeats

When a person performs the same copy-paste sequence weekly, it is worth automating. Below that frequency, the maintenance cost of a workflow exceeds the time it saves.

Self-hosted options such as n8n keep costs flat as volume grows and keep sensitive records inside your own infrastructure.

Layer three: specialists against measured pain

Only buy a specialist tool when you can name the bottleneck and the hours it consumes. 'Design takes three days per campaign' justifies an image tool; 'it looked impressive' does not.

Set a review date at purchase. Any tool below 30% seat usage after a quarter gets cancelled without debate.

Frequently asked questions

What should a five-person team budget?

Roughly $100-$250 per month covers assistant seats plus one automation plan; specialist tools should be justified case by case.

Should we self-host anything?

Only if you have someone who owns operations and a genuine data-residency requirement.
