The problem
In a company of 10 to 100 people, technology carries a lot of weight: the product, the website, back-office systems, internal tools, data, security. Technical decisions commit the company for years.
Yet technical leadership doesn’t always fill a week. A team of five developers needs someone to set direction, hire well, and settle architecture choices. It doesn’t need that person in meetings every day.
So the company faces a false choice: hire a CTO too early, or go without one for too long.
What a full-time CTO costs
Salary is only part of it. Add:
- payroll taxes, benefits, and bonus
- equity, which experienced candidates often expect
- recruiting: search firm fees, leadership time, and months of searching
- the risk of getting it wrong: a bad CTO hire shows after six months, and their decisions stay after they leave
For a small company, it’s often the most expensive and riskiest hire it will make.
What having no CTO costs
Without a CTO, technical decisions still get made. By default, by a founder with no time, by the longest-serving developer, or by a vendor whose interests lie elsewhere.
The consequences show up later, and cost more:
- an architecture that can’t handle growth and has to be rebuilt
- total dependence on one developer or one agency
- bad hires, because no one can properly evaluate candidates
- vendors billing for work no one checks
- security holes found by a customer or an attacker
- a due diligence that lowers the valuation, or kills the deal
- AI adoption left to individual initiative, with no rules or measurement, or no adoption at all
What a fractional CTO changes
The right level of experience. A small company often couldn’t attract a CTO with 20 or 25 years in the field full-time. Fractional, it can.
The right amount. The company pays for the leadership days it needs, and adjusts the cadence as things change.
An outside view. A CTO who has seen other companies at the same stage spots problems earlier, and knows what worked elsewhere.
A prepared hire. When the company is ready for a full-time CTO, the fractional CTO knows exactly what profile to look for, joins the interviews, and onboards the successor.
An AI transformation that gets led. The fractional CTO finds the use cases, builds them with the teams, and runs an adoption plan, in engineering and elsewhere.
No permanent commitment. No long-term employment contract, no severance, no probation period to manage.
Signs it’s time
- the founder spends more time on technical issues than on sales or product
- no one can say for sure whether the engineering team is any good
- releases keep taking longer, with no clear explanation
- the company depends on a single developer or a single agency
- a major technical hire is coming up
- a fundraise, a sale, or a large customer demands precise technical answers
- the CTO just left. In that case, see interim CTO
When it’s the wrong answer
- All you need is development capacity. A freelancer or an agency will cost less.
- The engineering team is already several dozen people. Day-to-day leadership fills a week: you need a full-time CTO.
- Leadership isn’t ready to delegate. A CTO with no authority to decide changes nothing.
Bottom line
For a small or mid-sized company, the question isn’t “do we need a CTO?” but “how much CTO do we need?” As long as the answer is less than a full week, fractional is the most effective option.
