Official press release from Astek

Astek, a global engineering and technology consulting group, announces the acquisition of Quantion, a leading Spanish digital transformation specialist. Founded in 2015 in Barcelona, Quantion has established itself as a trusted partner for major European clients thanks to its “Digital Factory 360º” model, which combines technological innovation, integrated business solutions and strong delivery capabilities. This acquisition strengthens Astek’s footprint in Spain and consolidates its position among the leading digital players in Europe.

Strengthening European Presence

With over 150 experts and an annual growth rate close to 30% since 2020, the acquisition of Quantion represents a new milestone in Astek’s European expansion. It is also a key growth driver in Spain, where the Group now employs 500 professionals.

As Barcelona joins Astek’s network of Global Delivery Centers, it becomes a strategic hub, enhancing the Group’s near-shore offering and reinforcing relationships with major European clients.

A Strategic Alliance in High-Value Expertise

The integration of Quantion enables Astek to strengthen its expertise in three key areas: customer experience, data and artificial intelligence, and cloud infrastructure.

In addition, Quantion brings strong complementarities in the travel and airline sector, where Astek has established itself as a European leader. This activity generated more than €150m in revenue in 2025 and continues to show strong growth.

Through this acquisition, the Group further enhances its ability to support clients with their most ambitious transformation projects, addressing challenges of technological and digital complexity, business knowledge, and economic competitiveness.

Strong Strategic and Cultural Synergies

Quantion also stands out for its entrepreneurial culture, focused on innovation, the delivery of complex projects, and attracting top-tier technology talent. These values are fully aligned with those of Astek, where innovation and excellence lie at the heart of client value creation.

Julien Gavaldon, Chairman of the Management Board of Astek, commented: “The integration of Quantion within Astek represents a tremendous growth opportunity to accelerate our innovation momentum and provide our clients with even more effective digital solutions to support their transformation strategies.”

Jordi Griful, President of Quantion, added: “Joining Astek, a group that shares our DNA of innovation and operational excellence, is a major lever to pursue our commitment to clients and strengthen the Group’s impact on the European market.”
