Is your technology stack overdue a clean-up?
Most technology stacks weren't planned — they accumulated. When businesses actually look, 20–30% of software spend is usually doing nothing useful.
Every few years, someone in the business pulls the software spend report and gets a shock. Not because any single tool is expensive — because the total is, and half of what's listed, nobody can quite explain.
That's how most technology stacks get built. Not through planning, but through accumulation.
How it happens
A new joiner brings a tool they used at their last company. A client insists on a particular platform. Someone signs up for a free Notion workspace and never migrates back. An old system gets quietly retired but the licence doesn't get cancelled.
The trouble is that reasonable decisions compound. What made sense at £500k revenue doesn't always make sense at £2m. What worked in 2019 isn't necessarily what you'd choose today. The tools stay; the business moves on.
What it costs
The obvious cost is money. Redundant licences, overlapping tools, seats never removed when someone left. Most businesses, when they actually look, find 20–30% of software spend is doing nothing useful.
The less obvious cost is complexity. Every system is an integration point. Every integration is a fragility. The more moving parts, the harder it becomes to change anything without breaking something else.
The one most people miss: knowledge risk. The system that only one person understands is a liability. The one nobody fully understands is worse.
What a rationalisation actually involves
It starts with a complete inventory — not just what's being paid for, but what's actually in use, who owns it, and what problem it solves. Most businesses find surprises before they've touched anything else.
From there: consolidation. Which tools do the same thing? Which licences can be downgraded or cancelled? Which systems are being stretched past what they were designed for?
Then the harder question: what's missing? A rationalised stack isn't a smaller one. It's one that fits where the business is now.
When to do it
Once a year. The right trigger is usually a financial review or a growth inflection — when headcount has jumped and suddenly the tools that worked for ten people are straining under thirty.
The warning signs come earlier: workarounds everyone's stopped questioning; data living in two systems with no clear source of truth; onboarding taking longer than it should because nobody can explain how everything connects.
When those show up, the stack is overdue a look.
The businesses that stay on top of this aren't careful about buying tools. They're disciplined about reviewing them.

Most mid-sized businesses don't need a full-time CTO. They need experienced technology thinking, available consistently, at a scale that fits where they are now.
What should you actually do about AI?
Most founders told to "get an AI strategy" haven't identified which problem they want it to solve. That's usually the better place to start.
Where does your data actually live?
When you sign up to a SaaS tool, your data goes somewhere. Most UK businesses haven't decided where — and clients in legal, healthcare, and financial services will ask.
