Groupe AG3i – Strategic Marketing Support for High-Growth Expansion

Marketing Strategy, Communications & Branding by Change Muse

About the Company

Groupe AG3i began as a small maintenance company and, under the leadership of Mr. Christian Ghio, evolved into a major player in the building and maintenance sector in the PACA region (South of France). Its remarkable growth led to two major milestones:

• A successful IPO on the Euronext Paris regulated market

• The acquisition of Adessia, a company specializing in industrial access control and security management

This rapid expansion required a flexible, forward-thinking marketing strategy to evolve in step with the company’s ambitions.

The Challenge

As AG3i scaled rapidly, the company faced several key challenges:

• Navigating new markets and strategic transformations

• Aligning internal and external communications with a fast-moving business strategy

• Maximizing impact on a limited marketing budget

• Ensuring that marketing could adapt to the evolving needs and vision of the CEO

The task was to provide both immediate tactical support and a long-term strategic marketing foundation to help AG3i grow with confidence and clarity.

The Solution

Change Muse worked closely with AG3i and its leadership to build a comprehensive, growth-aligned marketing approach. Key contributions included:

• Development of a new corporate website to reflect the company’s positioning and growing capabilities

• Ongoing internal and external communications support, ensuring consistent messaging during each stage of the company’s evolution

• Strategic guidance and execution of corporate events, aligning messaging with the company’s brand and business milestones

• Creation of scalable marketing tools designed to support future acquisitions, brand consolidation, and investor communications

The approach was tailored, agile, and always aligned with the CEO’s evolving vision—ensuring marketing was never an afterthought, but a core driver of growth.

The Result

AG3i emerged with a stronger, more relevant brand presence and a professional marketing framework that supported the company through key transitions. This foundation played a direct role in enhancing investor confidence and contributed to the success of:

• The company’s IPO on Euronext Paris

• The acquisition and integration of Adessia

This project is a clear example of how Change Muse supports fast-growing companies with smart, scalable marketing strategies that grow with them.
