“Grow with confidence”

Account manager

“I arrived at EdE in March 2015 as a CEE manager. I was then able to move on to work as an adviser, then as coordinator and today I am an account manager. I feel the company provided me with trust and great opportunities, by letting me move up within the same department. What I enjoy most day-to-day is the interaction with different employees to get the job done. What I like most about the firm more generally is that even after all the progress I’ve made I can still ask, 'what's the next step'? This is what gets me out of bed in the morning: nothing is set in stone. There are always new ideas to explore and new challenges to meet.”


“It's inspiring to know the company sets no limits, for employees or for itself. Once you realise this, anything is possible.”
Key Account Manager

“I joined Économie d’Énergie in 2012 as an administrative officer. I soon won their confidence through my personal commitment and the results I got with the tasks I was given.
In 2 years, I worked up through the portfolio manager position to the deputy supervisor. I was made team supervisor in 2013. Since 2014, I’ve been working in Sales as the Key Account Manager. Today I run a client portfolio that includes the biggest energy suppliers in France.
What I like about Économie d’Énergie is the positive energy in the air and the constant dynamism that allows the company to continually grow. In my average day, I meet and work with enriching clients and partners and keep me growing professionally. In Économie d’Énergie, I find that my colleagues are always available to help or lend an ear, even when they're working multiple projects. Our multi-disciplinarity and diverse team and the variety of skills we cover have really had an influence onme. There's a real openness, a real willingness to bring on the most committed employees, particularly those who want to develop professionally and who are interested in energy efficiency. It's inspiring to know the company sets no limits, for employees or for itself. Once you realise this, anything is possible.” Parce que chez Économie d’Énergie, c’est la pluridisciplinarité et la diversité des profils et des compétences qui m’ont le plus marquées. Il y a une vraie ouverture et une réelle volonté de faire grandir les collaborateurs les plus investis, souhaitant s’y développer. Savoir que la société n’impose et ne s’impose aucune limite est très inspirant. Car à partir de ce constat, tout est possible.”


“A spirit of initiative and independecne is promoted and encouraged: this is what drives me to grow.”

Customer Relations Manager

“I have been with Économie d’Énergie since the start, which means I have been able to watch and learn how to set up a company and how to develop different service chains. I started in October 2011, as an administrative officer on a 4-month temporary contract. After that, I joined the company as a client relations officer on a work-study basis (BTS NRC). When that finished, the company offered me a permanent contract. Having worked as a client relations officer for 4 years, I got the chance to move up to Assistant Manager of Client Relations; a year and a half later I was running the department. The human scale of the company and closeness among colleagues means I can stay in touch with all aspects of the business and build skills fast, particularly as the spirit of initiative and independence are promoted and encouraged. These two factors were what drive me to grow.”
