Our history

A hyper-growth scale-up in Lyon

Founded in 2007 in Lyon, GAC Software (formerly GAC Group) was born out of its founders’ desire to simplify corporate asset management through digital technology. Since launching our first software solution dedicated to vehicle fleet management, we have expanded our expertise by developing solutions that now cover real estate portfolio management and employee equipment management. At every stage, our ambition remains the same: to provide businesses with greater traceability, control, and performance, while minimizing hidden costs and facilitating the transition to a sustainable model. Today, more than 950 clients trust us, and we continue to expand internationally.

A growth trajectory driven by innovation

From the outset, we have been developing software focused on performance and traceability, initially for automotive and telecom fleet management. Our approach, recognized by an Innovation Trophy, has strengthened the confidence of our customers: in 2017, around a hundred of them placed their trust in us, and our offering was extended to include the management of infractions and real estate assets; and in 2024, our flagship software, GAC Car Fleet, will pass the milestone of 500,000 vehicles managed, with innovative new functionalities, including artificial intelligence, to support our customers as their businesses evolve.

GAC Software goes international

For several years now, the group has been expanding internationally, with the challenge of accelerating this expansion while preserving the company’s DNA. Today, GAC Software is present in over 30 countries in Europe and Africa. Since 2022, two new partners, New Alpha Verto and Bpifrance, have joined the adventure at our side to support us in this ambitious project.

2025: from GAC Group to GAC Software, a new name for the same ambition

This new name embodies the natural evolution of our company and reinforces our position as a business software publisher for professionals. GAC Software more clearly expresses our core business: designing robust, specialized and scalable SaaS software solutions to optimize enterprise asset management. This change is part of a dynamic of growth in France and internationally, continuous innovation and reinforced commitment to our customers.
