How CTOs Evolve: From Engineer to Executive Leadership

In a fast‑growing tech startup, a CTO typically goes through three growth stages:

Engineer: the CTO starts by building the product and works hands‑on with code. Manager: the CTO’s day becomes filled with meetings and people‑management, overseeing dozens of staff. Executive: the CTO has built a full technology‑management team but now wonders how to keep passion and drive the organization forward.

Engineers who take the management path often overlook the difficulty of moving from stage two to three. When a startup reaches a stable growth phase, transitioning from technical leader to senior CTO usually encounters several problems:

1. Communication is opaque: technical and non‑technical issues are not shared at the same level of understanding across the team. 2. Dismissing dissent : plans are made without considering business needs, and opposing voices are ignored. 3. Lack of process control : there is no long‑term planning or predictable staffing, affecting quality and delivery. 4. Personnel decisions : the company fails to hire better managers and experts or to remove underperforming staff.

To solve these, identify the root causes.

Root cause one: You don’t understand what other department leaders are doing

As the company grows, the CTO must interact with more senior leaders from other departments and should not neglect communication with them.

When the company moves from Series A to Series B financing, the management team becomes more specialized. In senior meetings, the CTO should know how to communicate effectively with other leaders.

1. Discuss product and technical needs

In the early stage, the technology department can seem like a black box to sales and marketing. Without proactive communication, shared knowledge is missed.

As a tech leader, you have a unique opportunity to convey what the tech team is doing, how goals are set, priorities are chosen, and risks are managed. This helps sales explain the product better, enables marketing to plan campaigns, assists finance in budgeting, and guides HR in hiring.

2. Understand other departments’ needs

If the CTO knows other leaders’ needs, they can respond constructively rather than dismissively, saying things like “If we change this, we need … What do you think?”

Knowing what other leaders need helps the CTO focus on actions that drive overall company growth.

Root cause two: You misunderstand the company’s needs

1. Understanding sales and marketing

When the company enters a new growth phase, product and technical discussions are gradually replaced by sales, marketing, and strategic topics. Technical issues may no longer be the top priority; the CTO must understand and support this shift.

Many startups initially lack clarity about their product, customers, and revenue model, unlike public companies that forecast revenue quarters ahead.

Therefore, predicting future revenue is crucial. Achieving growth means forecasting sales, retaining customers, and having a predictable product and performance, as well as hiring the right talent.

2. Understanding the board

The board’s concerns shift from product development and customer discovery to sales, marketing, and corporate management as the company matures.

Even if you cannot attend board meetings, you can gather information from colleagues and internal channels to anticipate challenges and plan resources, deciding whether more staff or stronger teams are needed.

In summary, when a company moves from the startup stage to a growth stage, the CTO’s goals and role must evolve. A managerial CTO should stay focused on the company’s current needs and maintain good communication with other leaders. An effective executive should:

1. Identify the real problem, not just surface symptoms. 2. Find the next challenge during good times and explain why it matters. 3. Craft specific, flexible solutions for the next goal. 4. Clearly convey what the team is doing and why it’s necessary. 5. Execute decisively.

Since you chose the management path, work will gradually shift from writing code to addressing the broader context behind the code.
