Coles Group CTO Departs After Year in Role – What’s Next?

Leadership changes in tech can send ripples through an organization. For Coles Group, the departure of Chief Technology Officer Mike Sackman after just one year in the role marks a pivotal moment in the grocery retailer’s digital transformation journey. Let’s unpack what this means for Coles and its future tech strategy.

Mike Sackman’s Brief Tenure and Key Contributions

Mike Sackman joined Coles Group in March 2025, bringing 30 years of technology leadership from UK retail giants like John Lewis Partnership, Waitrose, and Argos. His mandate was clear: drive innovation under Coles’ 3D strategy—focusing on food and drink as a destination, digital acceleration, and operational consistency.

During his tenure, Sackman spearheaded initiatives such as:

• Rolling out AI tools like ChatGPT Enterprise and Copilot to streamline workflows
• Enhancing cybersecurity to protect customer and employee data
• Modernizing IT infrastructure to support digital-first retail operations

Despite these achievements, Sackman is returning to his native UK, leaving behind a legacy of practical tech upgrades and a foundation for future innovation.

Interim Leadership: COO Matt Swindells Steps In

Coles Group has appointed Chief Operating Officer Matt Swindells as interim CTO. This move ensures continuity while the company searches for a permanent replacement. Swindells’ operational expertise will be critical in maintaining momentum on existing projects.

What This Means for Coles’ Tech Strategy

Swindells inherits a roadmap shaped by Sackman’s focus on customer-centric technology. Key priorities include:

1. Expanding AI integration for personalized shopping experiences
2. Strengthening cloud-based systems for scalability
3. Enhancing data analytics to drive inventory and supply chain efficiency

However, the transition highlights the challenges of sustaining tech leadership in a competitive retail landscape. Coles must now balance innovation with operational stability.

Broader Implications for Retail Tech Leadership

Sackman’s departure follows a broader trend of tech leadership reshuffles in retail. From 2024 to 2025, major retailers have restructured IT teams to adapt to AI-driven commerce and evolving consumer expectations.

For Coles, the challenge lies in maintaining its digital edge while addressing the complexities of a hybrid workforce and cybersecurity threats. The interim leadership period will test the company’s agility in executing its 3D strategy.

What’s Next for Coles?

As Coles searches for a new CTO, the focus will remain on delivering tangible outcomes for customers and employees. The incoming leader must:

• Build on Sackman’s cybersecurity and AI foundations
• Align tech initiatives with Coles’ long-term growth goals
• Ensure seamless integration of new tools into daily operations

The retail sector is watching closely to see how Coles navigates this leadership transition. Will it emerge stronger, or will the shift disrupt its digital momentum?
