There are specific headcount inflection points where IT infrastructure decisions get materially harder — 15 staff, 25 staff, 50 staff, 100 staff. The tools and setups that worked at 8 people start breaking around 15. What works at 25 falls over at 50.
Most owners only find out at the point of failure. Which is a very expensive time to redesign infrastructure.
Scaling advice matters most at inflection points. And most owners only look at infrastructure after it's already breaking
What breaks around 15 staff
- Shared credentials. The password everyone knew becomes a legal exposure.
- Ad-hoc file sharing. People start emailing files to themselves.
- The mate's-rate IT support model. One person can't cover the workload any more.
- Ownership of decisions. Who approves a new tool? Who's the security lead? Nobody's sure.
What breaks around 25 staff
- The single wiki nobody maintains. Documentation stops being reliable.
- Onboarding drift. New starters take longer and longer to get productive.
- Vendor sprawl. Twelve SaaS tools; nobody knows what half of them cost.
- Data classification. What's confidential? What's public? Nobody has a shared answer.
What breaks around 50 staff
- True identity governance is needed. Groups, roles, access reviews.
- Real change management matters — not "we told everyone in Slack."
- The QBR rhythm starts to reveal genuine risk you didn't have to worry about at 20.
- Compliance conversations get real. Especially if you sell into enterprise, government or regulated verticals.
What we do about it
Scaling and roadmap advice sits inside IT Strategy & Consulting alongside Cloud Solutions, so infrastructure decisions today don't need re-doing in 18 months. We look 12 months ahead as a matter of course — because the decision that's right for a team of 12 isn't the decision that's right for a team of 25, and you shouldn't be finding out at the point of failure.
The three questions we ask at every review
- What's your target headcount 12 months from now?
- What are the top 3 workloads you'd struggle to scale?
- What are the top 3 tools you'd stop paying for tomorrow if you could?
Nine times out of ten, those three answers give you a shortlist of the things to do next.
Ask for a 12-month scaling review. We'll benchmark you against where you say you're headed.
