CTO-On-Call: Why Small Businesses Don't Need a Full-Time CTO
Every small business reaches the same inflection point: you need someone who can make technology decisions, but you can’t afford the salary a proper CTO commands.
So what do most businesses do? They either:
- Hire an IT Manager — someone who can keep the lights on but isn’t equipped to think strategically
- Promote a tech-savvy employee — who becomes overwhelmed and distracted from their actual job
- ** wing it themselves** — making expensive mistakes that compound over years
- Try to go without — hoping technology will somehow sort itself out
None of these work. Here’s why — and what actually does.
The Problem with “IT Guy”
Most small businesses end up with what I’ll call the “IT Guy” model: someone who handles computers, installs software, and maybe sets up the WiFi. This person is valuable for what they do, but they’re not a CTO.
A real CTO does three things your IT Guy can’t:
1. Strategic Technology Planning
A CTO thinks about where technology needs to go in 3-5 years. They understand how tech choices now create (or limit) options later. They can evaluate whether a technology investment today will pay off tomorrow.
Your IT Guy is busy keeping today’s systems running.
2. Vendor and Technology Selection
When you need a new CRM, a CTO doesn’t just Google “best CRM” and pick the first result with good reviews. They understand your specific needs, evaluate total cost of ownership, consider integration complexity, and make recommendations based on evidence — not marketing.
3. Risk Management
A CTO understands security implications, data compliance requirements, and the real cost of downtime. They ask “what happens if this fails?” before it fails.
What a CTO Actually Costs
The market rate for an experienced CTO in London starts around £80,000-120,000 per year. Add employment costs, benefits, and the reality that you’ll need someone senior enough to actually add value, and you’re looking at £100,000+ before they write a single line of code.
For a small business with 5-20 employees, this is often simply not justifiable. You need CTO-level thinking maybe 10-20 hours a month. The rest of the time, you need someone managing the day-to-day.
The CTO-On-Call Model
This is where CTO-On-Call services make sense. Instead of hiring one person full-time, you get access to CTO-level expertise on an as-needed basis.
What You Actually Get
| Full-Time CTO | CTO-On-Call |
|---|---|
| £100k+ annual cost | £25-75/hour |
| Available full-time | Available when needed |
| Needs to manage others | Direct access |
| May have gaps in expertise | Broader experience across clients |
| Single point of failure | No employment risk |
The Key Insight
Most small businesses don’t need someone who can do everything — they need someone who can decide what’s worth doing and who can do it.
A CTO-On-Call can:
- Review your technology stack and identify waste
- Evaluate vendor proposals before you sign contracts
- Plan your technology roadmap for the next 12-18 months
- Advise on security and compliance
- Interview technical candidates for you
- Be the technology voice in strategic meetings
When IT Manager + CTO-On-Call Makes Sense
Here’s the model that actually works for growing small businesses:
IT Manager (or managed IT service): handles day-to-day operations, user support, routine maintenance, and keeping systems running.
CTO-On-Call: provides strategic direction, makes key technology decisions, reviews vendor proposals, and plans long-term technology direction.
The IT Manager executes. The CTO-On-Call decides.
This isn’t about replacing your IT person — it’s about making sure you have both operational and strategic technology coverage.
The Real Cost of Not Having CTO-Level Thinking
Let’s talk about what happens when small businesses make technology decisions without proper guidance:
The SaaS Trap
I audited a business last month that was paying £2,400/year for a project management tool. They were using about 15% of the features. The owner didn’t know there were alternatives, and no one on the team had ever evaluated whether the cost was justified.
That’s £2,400/year for something they could have replaced with a self-hosted solution running on a £10/month VPS.
The Integration Mess
Another client had 7 different SaaS tools that didn’t talk to each other. Data was being re-entered manually between systems. No one had ever evaluated the integration options or the time cost of manual data entry.
The total “time tax” was about 3 hours per week across 4 employees. At £25/hour, that’s £300/week, or £15,600/year. For tools that could have been replaced with an integrated system.
The Security Gap
Small businesses are increasingly targeted by attacks precisely because they often lack proper security thinking. A CTO-On-Call can review your security posture, identify gaps, and prioritize fixes based on actual risk.
What CTO-On-Call Looks Like in Practice
Here’s how it typically works:
Phase 1: Discovery (2-4 hours)
We start with a technology audit. This isn’t just about what software you’re using — it’s about understanding your business goals, your pain points, and your growth plans.
Output: A written report covering:
- Current technology stack assessment
- Identified waste and inefficiencies
- Quick wins that can be implemented immediately
- Medium-term recommendations
- Technology roadmap for the next 12-18 months
Phase 2: Ongoing Advisory (As needed)
After the initial audit, you have access to technology advisory support:
- Review vendor proposals before you sign
- Evaluate new technology decisions
- Answer specific technology questions
- Provide written recommendations for major decisions
- Be available for calls when strategic decisions arise
Phase 3: Implementation Oversight (Optional)
For larger projects, we can provide implementation oversight to ensure projects stay on track and technology decisions are executed properly.
Is CTO-On-Call Right for You?
CTO-On-Call makes sense when:
- You’re spending £500+/month on technology but don’t have a technology strategy
- You’re making technology decisions without dedicated technology leadership
- You’re growing and need to make good technology investments now
- You’ve had technology failures that cost you time and money
- You want a second opinion on major technology decisions
It makes less sense when:
- You have a capable CTO already
- Your technology needs are minimal and stable
- You’re in a phase where survival is the only priority
