"We'd like to extend our warmest thanks to the Cristal Decisions Energy team, whose professionalism supported us very effectively in several assignments aimed at optimizing some of our expenses."

"We've been working with Cristal Decisions on energy issues for 8 years now. The expertise and know-how of Cristal Decisions' consultants on these subjects have really helped the company grow. In addition to the necessary determination of a strategy adapted to our needs, the sound advice of Cristal Decisions' experts now enables us to manage our entire portfolio of residences (300 sites) efficiently. Thank you to all those who today make up the Cristal Decisions Energy Experts, for their presence, advice and expertise in these different markets."

"Working with Donald and Ludivine from Cristal Decisions is a pleasure. They know how to make themselves available and provide clear, high-quality explanations. We've been working together for almost 2 years now, and I still see real added value in their advice and work. I trust them and appreciate their day-to-day support in helping me achieve my objectives in terms of savings, but also in terms of decarbonizing our production. I recommend them."

"We would like to congratulate you on the way in which the tender and negotiation of the gas contract for Colruyt have been conducted over the last few days, leading to the signing of conditions that are almost perfectly in line with our initial and agreed requests. It's a job we've enjoyed following with you, and one that further strengthens our good collaboration as well as the confidence we have in your teams."

Cristal Décisions managed the entire preparation of the application file with the various stakeholders. Thanks to their efforts, diligence, and persistence, we obtained all the expected subsidies"

"We would like to thank you for the excellent support and quality of your service in helping us renew our energy contracts at our 3 sites.

We are very satisfied with this collaboration, the results of which exceeded our expectations."
