After graduating from HEC Paris in 2006 and from SciencesPo Paris in 2007, Alexis began his career in 2008 as a strategy consultant at Strategy&. In 2013, he specialized in digital health by creating the B2B department Withings, which offered remote monitoring solutions to health professionals. In 2017 when the company was bought by Nokia, he took over as head of the company's Boston office. Later in 2018, he co-founded Embleema, a platform for generating real health data. After returning to France in 2019, he became co-founder of Greenly, where he is now the CEO.

Through his background with Withings, Alexis developed an understanding for how technology can make it possible to measure what is otherwise invisible. Furthermore, how digital means can be used to invent new economic models to finance behavioral prevention, by creating immediate incentives for more virtuous behavior. He is now convinced that behavior change is the most effective way to fight against global warming, and that simple, painless measures must be generated on a daily basis to allow us to make a change.

His main objective is to find the most effective ways to encourage companies to take interest in their climate impact, and to get them started on the calculation of their CO2 emissions.

When he's not working on the development and growth of Greenly, Alexis works on improving his tennis skills, and traveling the world in search of new hiking destinations.

After graduating from Ecole Polytechnique with a degree in Data Science and Software Engineeting, Matthieu worked with Withings to see how their data can help hospitals, businesses, and pharmaceutical labs take advantage of the revolution in data exchange via interconnectedness.

Matthieu is even at the origin of the algorithm embedded in the smart watches with automatic stroke detection for swimmers! After this, he spent a year implementing the use of blockchain (the technology behind Bitcoin) so that patients could securely and reliably share their health data with clinical research.

What motivated him above all in creating Greenly was to launch a tool that allowed users and companies to have concrete results in terms of measuring and reducing their carbon footprint.

At Greenly, Matthieu leads the Tech team. His role is to ensure the best possible functioning of the technical aspects, and to assure that each member on his team can work in the best conditions, technically and humanely.

A recent graduate of the Ecole Centrale de Nantes and the Technical University of Denmark (DTU), Reda is a young engineer passionate about energy and environmental issues.

It was during his Masters in “Sustainable Energy” in Denmark that he became aware of the complexity of the phenomena at the origin of the current energy crisis. Most of all, he focuses on the gap that exists between the theoretical models - which naturally appeal to his scientific side - and the solutions applied at the societal level. With the goal of closing the gap which separates the academic and civil worlds, he joined Greenly during his end-of-studies internship in January 2021.

Within the company, Reda carefully monitors the methodological rigor of the carbon footprint calculations, ensuring that they comply with the latest levels of scientific knowledge. Among his favorite subjects: the combination of input-output tables and macroeconomic models to assess consumption emissions related to different sectors of the economy.

When he’s not at the office, Reda can be found relaxing in a park with a book, or exploring a new hike on foot or by bike.

After graduating from the University of Bath with a degree in Social Sciences in International Management and Modern Languages (Spanish), Chloe was able to learn English and Spanish in the multicultural environment that underpins our societies. The choice of a specialization in the political economy of sustainable development allowed her to support her convictions and skills related to the energy transition of international companies. After two internships in Spain in the fields of efficient e-waste management and sustainable agricultural transition, she became aware of the role of the private sector in the ecological transition, and more particularly that of the large groups whose reduction trajectory relies on the commitment of their suppliers who are asked to reduce their emissions accordingly. At Greenly, Chloé first joined the SRD Inbound team, which is responsible for understanding and responding to the needs of companies and organizations in order to provide them with the best support offer for newly acquired prospects. Following her contract renewal, she had the opportunity to move into the SRD Outbound team where she currently manages the portfolio of the food and media sectors in France. Her personal convictions have guided her career choices for a long time and she was elected President of the Oxfam Bath Society at the University. Since her return to Paris, Chloé has been an avid runner, rock climber, cinema goer, and Asian cooking class participant.

Chloe graduated with a Bachelor's degree in Commerce from McGill University in 2020, double majoring in Marketing and Entrepreneurship. She then specialized in Marketing at the ESCP Business School in Paris, joining the MCS in Marketing and Communication. Inspired by Greenly's mission, she joined the team in November 2021 after an internship at BackMarket. Since then, Chloe has helped build the brand strategy in France, working on client communication, PR, social media, events, and content for sales to strengthen their campaigns. Her challenge is to shape the company's brand identity and messaging to generate awareness and create demand for a global audience. In her free time, Chloe enjoys yoga, hitting the slopes in winter, and kitesurfing during the summer.
