How is AI Reshaping CMOs into Chief Growth Architects?

The growing integration of AI in C-suite functions is reshaping the role of the Chief Marketing Officer (CMO) into what Boston Consulting Group (BCG) describes as a ‘Chief Growth Architect’.

As a customer-facing and digitally advanced department, marketing can serve as a crucial testbed for AI experimentation, laying a foundation for how these technologies could be implemented across an organisation.

The marketing profession has been transitioning over the past decade from a role centred on creative storytelling to one that harnesses data for campaign finalisation and delivering a measurable return on investment.

AI can heighten this analytical reasoning. In the report writersJessica Apotheker, Managing Director & Senior Partner at Boston Consulting Group, and Janet Balis, Managing Director and Partner, suggest that viewing an AI-first CMO as a ‘Chief Growth Officer’ will “design martech data flows and strategies that tear down silos and connect demand signals rapidly and seamlessly”.

For human resources departments, this signals a necessary change in the skills and capabilities required within marketing teams.

Redefining talent and team structures

The traditional marketing skillset is expanding. While creativity remains important the emphasis is moving towards a science-based approach enabled by AI.

This allows marketing leaders to act on changing consumer demand in real time. Jessica and Janet write: “CMOs will own the data inputs, commercial growth platforms and measurement models that form a state-of-the-art martech stack.”

This responsibility requires a new kind of talent. Although CMOs will still need to recruit tech specialists, a major part of the HR challenge will be to reskill marketing generalists, elevate strategic capabilities and redesign incentives around new human-to-agentic workflows.

This points toward a need for structured training and certification programmes to equip the existing workforce with the necessary competencies to manage and leverage AI tools effectively.

Fostering C-suite collaboration and skills

A successful transition depends on collaboration between the CMO and the Chief Technology Officer (CTO). According to BCG, the synergy of their combined expertise is essential to optimise performance and harmonise different systems.

The report explains that, when CMOs work with their CTO, they will “connect demand signals rapidly and seamlessly to an integrated growth agenda”. This partnership model could become a blueprint for other departments.

According to BCG research, the top 5% of companies creating substantial value from AI are 50% more likely to have shared business-IT ownership of their AI operating models.

From a talent perspective the most adept CMOs will partner with IT to build a small and dedicated team of tech experts within the marketing function itself, creating a hybrid team structure.

Balancing technology with human capability

CEOs should look for a high level of AI curiosity and technical fluency in their marketing leaders. They must be able to understand the details of how data flows through the organisation and what is being done to improve ROI on every platform.

This change may cause friction with other C-suite executives, who may perceive the CMO as moving outside of their traditional remit.

However BCG suggests this resistance should be viewed as a sign of progress in organisational transformation. Amidst these technological changes the uniquely human ability to connect with emotion must not be lost.

An AI-first CMO should ensure human-driven storytelling remains central to their strategy. AI is a powerful tool for personalisation and prediction but it lacks the capacity for emotional connection.

The marketing department’s journey with AI could become an invaluable source of insight into customer behaviour that can “inform branding, media and creative strategies, product innovations, pricing and discounting decisions, and resource allocation”, says BCG, demonstrating how technology and human skills can combine to create growth.
