Small team, big leverage: how AI changes the right team size
Why a $5M services business with AI might not need to grow to 30 people the way the playbook used to say it should.
The old growth playbook said: $5M revenue means 25–35 staff in a services business. Hire ahead of revenue. Build the org chart you would need at $10M before you get there.
That playbook is breaking. The $5M services businesses we work with now run with 12–18 staff and look profoundly different inside than they did three years ago.
What's changed
Most of the admin layer of a services business — first-touch, scheduling, follow-up, billing chase, basic reporting — is now handled by agents. The staff that is left is more senior, better paid, and doing more interesting work.
The trade-off: smaller team, higher per-head pay, much higher per-head leverage. EBIT margins on a $5M services business have moved from 12–18% (with old playbook) to 22–32% (with the new shape).
What this means for hiring
We tell operators: don't hire the next admin. Hire the next senior. Move the admin onto the systems. The seniors you bring in expect AI to be everywhere; if your business doesn't have it, the good ones won't take the role.
Small team, high pay, AI underneath. That is the new shape of a profitable services business.
When this doesn't apply
Trades businesses with vans on the road still need the vans and the people in them. The leverage shows up in the office, not on site. A $5M plumbing business will still have 14–18 vans regardless.
