In his new role, the executive will focus on expanding the potential of Stefanini Group’s portfolio to create value for clients, support acquisitions and develop the company’s next generation of leaders

Stefanini GroupStefanini Group, a global technology consultancy with an AI-First mindset, has appointed Guilherme Stefanini as CEO of North America and Asia-Pacific (APAC). In his new role, the executive will focus on accelerating the company’s growth across the regions, particularly in the United States, where Stefanini Group has operated for more than 25 years and serves more than 200 clients.
He will continue working to help companies address complex business challenges through technology, with operations spanning sectors including financial services, retail, manufacturing, consumer goods and services.
“Over the past two decades, we have built a solid foundation in North America and, particularly, in the United States,” says Guilherme Stefanini. “There is significant room for us to expand our presence and help large companies address urgent challenges within their organisations. Over the past year, Stefanini Group’s clients recorded a 13% increase in sales and a 60% reduction in infrastructure costs. We achieved these results because we have built long-term relationships with our clients, developing and implementing customised technology solutions that make them better prepared for the future.”
Artificial intelligence will also play a central role in the company’s long-term vision for North America. In 2024, Stefanini Group opened an AI Centre of Excellence in Southfield, Michigan, at its US headquarters. The facility brings together professionals developing technology solutions as part of the company’s global AI team, bringing development capabilities closer to North American businesses and strengthening collaboration across the region.
“Some of the world’s most influential companies are headquartered in the United States, making this market one characterised by both enormous scale and the complexity of the business challenges we are prepared to solve,” adds Guilherme. “Being closer to our clients and expanding our presence across North America allows us to better understand their priorities and connect the capabilities of our global organisation with the most relevant challenges facing each business.”
Stefanini Group operates across different markets and sectors, including North America and APAC, and will continue its expansion with a focus on delivering results and creating value for clients.
Before taking on his new role, Guilherme served as CEO of Stefanini Marketing from 2020, where he grew the business sixfold, led the company’s global rebrand and helped unify Stefanini Group’s presence across more than 35,000 employees and 2,000 clients in more than 100 countries.
Under his strategic leadership, Stefanini Group structured its portfolio into seven global business units: Technology, Cyber, Data & Analytics, Financial Tech, Operations, Marketing and Manufacturing. The structure integrated capabilities from more than 40 strategic acquisitions.
Guilherme has been with Stefanini Group for 10 years and, since 2024, has served as CEO of Stefanini Marketing and Global CMO. He also contributed to INSEAD recognising the company as an ambidextrous organisation.
Guilherme is an organiser of INSEAD’s “Leadership in Digital Transformation” programme. A case study based on his work, “Creating an Ecosystem Strategy in the Age of AI”, became an academic reference and is studied at business schools around the world.
