The New CTO: From coder to transformation game-changer

My hot take on how the most technical role in the C-suite became the most complex leadership job in the organisation

Last week I wrote about how the CIO role has changed over the years, and how many of the leaders currently sitting in that role haven't changed with it. The response to that piece made one thing clear: this isn't a CIO-specific story. It's happening, in a slightly different way across all technology roles in the C-Suite, but especially to the CTO role.

The CIO and the CTO are, in most organisations I work with, the two most senior technology roles on the leadership team. If one is getting a facelift, it would be strange if the other wasn't.

I don't think I placed a single CTO into a role for the first 10 years of my exec search career. That certainly isn't the case anymore. The last couple of years has seen demand for the role skyrocket. Part of that is market demand for great technology leaders. But a bigger part, if I'm honest, is a shift in my own focus. I've moved away from major enterprise businesses and toward mid-market companies, where the CTO role tends to show up more often, carry more weight, and prove harder to fill well.

That shift in my practice has given me a different vantage point on what's actually happening to this role. And what's happening seems to me more significant than most organisations have recognised.

Much like the CIO role, the CTO title hasn't changed, but the job itself has changed almost completely.

Ask a board, or a CEO, what they want from their Chief Technology Officer and most will describe a version of the role that ceased to exist about five years ago. Someone who runs the tech stack, manages the engineering teams, and keeps the systems running. A highly capable operator working, largely, in the background.

That CTO, if they ever existed in their purest form, is gone. What has replaced them is something far harder to hire for, far harder to develop, and far harder to evaluate. And most organisations haven't kept the CTO position description up to date.

Why Mid-Market Makes This Harder

In large enterprise, the CTO role is demanding but cushioned. There are layers of specialists underneath: heads of architecture, security leads, data teams, transformation directors. They absorb much of the technical complexity, and the CTO can focus upward on strategy, board, and stakeholders.

In mid-market businesses, those layers don't exist. The CTO is closer to everything. They carry a broader remit with fewer people beneath them, which means they do more themselves. They sit closer to the commercial engine of the business, with less insulation between technology decisions and revenue outcomes. And they operate at a pace that enterprise organisations rarely match, with less governance, less process, and fewer places to slow down, reflect and think.

It is the combination of all three that makes mid-market CTO searches genuinely difficult. You need someone with the strategic range of an enterprise leader and the hands-on adaptability of an early-stage operator. That profile is extremely rare. And the pressure AI is placing on the role has made it rarer still.

From Gatekeeper to Strategist

At the start of the century, the CTO was, in essence, the organisation's chief gatekeeper. Responsible for infrastructure, systems architecture, hardware-software integration, and technical staff. Operationally critical, strategically peripheral. Rarely in the boardroom. Rarely expected to be. (The first CTO I placed actually turned up to his first board meeting wearing a Daffy Duck tie.)

That began to shift around 2010, as digital platforms moved from competitive advantage to survival requirement. Technology stopped being a support function and started being the product. CTOs were pulled into strategy conversations, tentatively at first, then with urgency.

By 2016, the shift was visible enough in the research literature to name. The best technology executives, one study noted, were already emphasising "business, organisational, and innovation skills more than technology prowess." That line landed with little fanfare at the time. In retrospect, it marked a turning point.

Four Jobs in One Title

A 2020 systematic review of technology executive competencies found the role had moved well beyond its traditional technical base and could now be grouped into four distinct functions: technologist, strategist, enabler, and innovator. Not four roles. One role, expected to perform all four simultaneously.

In practical terms, today's CTO is asked to set technology vision and strategy at the senior leadership level; drive digital transformation and innovation across the business; act as a translator between technical teams and the board; and shape organisational priorities across cybersecurity, data governance, talent development, and regulatory risk.

That is not a job description with some extra responsibilities bolted on. That is a fundamentally different leadership mandate wearing the same title it wore twenty years ago.

Research by Perri and colleagues puts it plainly: today's CTOs engage "a broad set of stakeholders" and must provide "a vision and strategy to execute within their organisation." A 2019 study was equally direct. Modern technology executives are "not n

arrowly profiled specialists focusing on purely technological issues." They sit in the top management team and act as a bridge across the entire organisation.

Three Horizons, One Leader

There is another way to see this expanded mandate, and it is one boards are increasingly explicit about. The modern CTO operates across three horizons at once: defending the existing business, extending it into adjacent opportunities, and disrupting tomorrow's business before a competitor does.

Most CTOs, left to their own instincts, overweight the first horizon. Productivity dominates, cost reduction consumes attention, and AI becomes primarily an efficiency story. But boards are looking for something closer to the opposite balance. Recent industry commentary puts the gap starkly: many CTOs spend the overwhelming majority of their effort on productivity, while boards expect the overwhelming majority of that effort to be directed at revenue growth.

That gap is not a communication problem. It is a structural mismatch between how the role has traditionally been performed and what it is now being asked to deliver. A CTO who is excellent at horizon one, keeping the lights on and the technology efficient, can still be quietly failing the mandate if horizons two and three are left unattended.

What the Research Says About Who Succeeds

If the role has changed this dramatically, it follows that the traits predicting CTO effectiveness have changed too. The data here is more counterintuitive than most boards expect.

A firm-level study by Chung and Kang across 140 US manufacturing companies found that CTOs with diverse functional experience and diverse industry backgrounds were associated with significantly greater radical innovation. Marketing experience in a CTO's background also mattered. Age, tenure, and education level did not.

Read that again. The credentials boards traditionally lean on when evaluating CTO candidates, seniority, years in role, educational pedigree, showed no significant relationship with innovation outcomes. Cross-functional range did. Breadth of industry exposure did.

In my own searches, this rings true. The CTOs who have hit the ground fastest in mid-market businesses are rarely those with the most decorated technical CVs. They are the ones who have operated across functions, who understand commercial pressure firsthand, and who can shift register fluently between an engineering stand-up and a board conversation.

A separate interview study of 30 CTOs by van der Hoven and colleagues found that CTO priorities cluster around three things: aligning technology with corporate strategy and business models; choosing technology entry and exit points at the right moments; and building compelling business cases for investment. These are not engineering tasks. They are leadership and commercial judgement tasks.

The Role Has Outpaced the Science

There is a deeper problem beneath all of this. The CTO role has evolved faster than our ability to understand, define, or develop the leaders who hold it. There's a reason why I coach more CTOs than leaders in any other role!

CEO effectiveness has decades of research behind it, with a mature literature on traits, styles, and behaviours. The CTO literature, by contrast, is thin. A 2016 review noted that even for CIOs, leadership-style studies were scarce and still framed in outdated categories. For CTOs, the evidence base is thinner still, assembled mostly from interviews, conceptual reviews, and a handful of firm-level studies.

The consequences are practical. Without a clear picture of what effective CTO leadership looks like, organisations default to hiring for the old profile: deep technical expertise, long engineering tenure, credentials in the right systems. They promote for the same reasons. Then they wonder why their technically brilliant CTO struggles to influence the board, build cross-functional coalitions, or translate a technology roadmap into a business case.

One study found that CTO effectiveness was associated with innovation and financial improvement, but also that effectiveness fell as firm size increased. This is a finding I'd extend in a different direction: in mid-market businesses, where the CTO has fewer people around them and less structural support, the leadership gap shows up faster and more visibly than it ever would in a large enterprise.

AI Has Accelerated Everything

All of this was already true before AI moved from experiment to operational reality. Now the pressure has intensified dramatically.

Every board is asking some version of the same question: what should we do with AI? It is, on the surface, a technology question. In practice, it is a strategy question, a risk question, a talent question, and a culture question simultaneously. The CTO is expected to answer all four and to do so in terms the board can act on.

A 2025 fintech study framing CTO leadership explicitly described the role as coevolving with strategy, requiring technical leadership, strategic thinking, collaboration, adaptability, resilience, innovation, data analysis, stakeholder management, and regulatory navigation. That list is not aspirational. For organisations taking AI seriously, it is the minimum viable CTO.

The IBM Institute for Business Value put it starkly in 2026: AI is pushing CEOs to redesign how C-suite roles are structured. Decision cycles are compressing. Functional boundaries are dissolving. The CTO who can only speak to technology is increasingly a liability in that environment, not an asset.

The Hiring Problem Hiding in Plain Sight

There is a final complication worth naming. The term CTO itself has become contested. Research identifies "hidden" CTOs, executives performing CTO functions without the formal title, and notes that in some organisations the responsibilities traditionally held by a CIO are being reallocated across both roles. One 2019 paper observed that the term is still associated with "dozens of contradictory definitions."

This is not an academic footnote. It means that two organisations can both claim to have a CTO and mean entirely different things. It means job descriptions are frequently describing the role that existed a decade ago. And it means that executives stepping into the title are often walking into a mandate that nobody has clearly defined. With 40% of new leaders failing in the first 18 months in a new role, this ambiguity can mean "taking an early bath", pardon my English sports idiom.

Organisations that get this right will do three things. They will rewrite what they are actually hiring for: not technical depth alone, but cross-functional range, commercial fluency, and the ability to lead through ambiguity at scale. They will invest in developing these capabilities in their current technology leaders before the gap becomes a crisis. And they will stop treating the CTO as a background operator and start treating them as what they have actually become: one of the most consequential strategic leadership roles in the organisation.

The title hasn't changed, but it's time the job description caught up.

Finding — and Landing — the Right CTO for Your Business

Identifying this kind of leader requires a different approach to search. At Vantyr Group, we work exclusively on senior technology appointments, including CTO, CIO, Chief AI Officer, Chief Product Officer, and the broader technology leadership team, for mid-market businesses, PE-backed portfolios, and scaling technology organisations. Our work is built around three integrated phases.

The first is executive search: evidence-based identification and evaluation of candidates against a brief that reflects what the role actually demands today, not what it demanded five years ago. The second is leadership assessment, where shortlisted candidates are evaluated using industry-leading psychometric testing as well as our own Growth Capacity Framework. This proprietary instrument measures the dimensions most predictive of leadership effectiveness in a complex environment: learning agility, feedback responsiveness, cognitive flexibility, and emotional regulation under sustained pressure.

The third phase is where most search firms stop entirely, or charge massive fees to manage: six months of executive integration coaching, structured around the first six months that a newly hired CTO is in role. The assessment findings don't get filed away after the hire. They transfer directly into the coaching brief, so every session is anchored to what we already know about this leader and what the role demands of them. The result is a CTO who gets up to speed faster, secures critical early wins and establishes themselves quicker in their new role.

If the argument of this article holds, that the CTO role has outpaced our ability to hire, develop, and evaluate the leaders who hold it, then the response cannot be a conventional search. It has to be something more integrated. That is what we built Vantyr Group to deliver.
