Guilherme Stefanini

Stefanini Group, a global technology consulting firm that employs 35,000 people across more than 100 countries, appointed Guilherme Stefanini as Chief Executive Officer for North America and the Asia-Pacific (APAC) region. He will direct the company's regional expansion, prioritizing the United States, where the firm has operated for 25 years and maintains a portfolio of over 200 clients.

In this role, Stefanini will oversee the implementation of enterprise technology solutions across the financial services, retail, manufacturing, and consumer goods sectors. The company develops custom software to modernize operations and manage infrastructure for corporate clients.

“Over the past two decades, we have built a solid foundation in North America, and especially in the United States,” said Guilherme Stefanini. “There is an enormous space to expand our presence and help large companies address urgent challenges within their organizations. In the last year, Stefanini Group clients recorded a 13% increase in sales and a 60% reduction in infrastructure costs. We achieved these results because we built long-term relationships with our clients, developing and implementing custom technological solutions that make them more prepared for the future.”

The company's expansion strategy relies heavily on artificial intelligence integration. In 2024, the firm opened an Artificial Intelligence Center of Excellence at its U.S. headquarters in Southfield, Michigan. The facility houses engineers and developers dedicated to building enterprise applications and aligns global teams to meet the specific technical demands of North American businesses.

“Some of the most influential companies in the world are headquartered in the United States, which makes this market characterized by both its massive scale and the complexity of the business challenges we are prepared to solve,” Stefanini added. “Being closer to clients, expanding our presence in North America, allows us to better understand their priorities and connect the competencies of our global organization to the most relevant challenges of each business.”

Prior to this appointment, Guilherme Stefanini served as CEO of Stefanini Marketing starting in 2020, where he increased the unit's revenue sixfold and managed a global rebranding initiative. Under his management, the parent company restructured its portfolio into seven global business units: Technology, Cyber, Data & Analytics, Financial Tech, Operations, Marketing, and Manufacturing. This architecture integrated capabilities from more than 40 corporate acquisitions.

An employee of the group for 10 years, he also held the position of Global Chief Marketing Officer starting in 2024. His work managing the corporate ecosystem and acquisition strategy became the subject of an academic case study published by the INSEAD business school, where he also organizes the Leadership in Digital Transformation program.
