About Hello Watt

Hello Watt operates as a key facilitator in France's residential energy transition market. Founded in 2016 by Sylvain Le Falher, Xavier Coudert, and Patrick Rousset, the company was established to address the complexities individuals face in managing and reducing their energy consumption. The founders identified a market opportunity driven by the deregulation of France's energy market in 2007 and the increasing availability of detailed consumption data from smart meters. Le Falher and Coudert, both graduates of Ecole Centrale de Paris, along with Rousset, an avionics engineer, chose to gain professional experience before launching the venture to ensure a solid foundation for their business.

The company's core offering is a multi-faceted platform centered around a free-to-use mobile application, which has surpassed one million downloads. This application connects to residential smart meters (Linky and Gazpar) to provide users with detailed tracking and analysis of their electricity and gas consumption in kWh, euros, and CO2 emissions. It disaggregates energy usage by appliance, compares consumption to similar households, and offers personalized recommendations for reduction. Hello Watt's business model is based on acting as a business facilitator for energy suppliers and installers. The company generates revenue by earning commissions when users switch to a new energy provider through its comparison tool or when they contract for energy renovation services with installers in its network.

Beyond consumption tracking, Hello Watt provides a comprehensive suite of services aimed at improving home energy efficiency. The firm offers an energy supplier comparison tool, manages energy renovation projects such as insulation, and installs renewable energy systems like heat pumps and solar panels. For solar installations, the application includes features to monitor energy production and optimize self-consumption. The company manages the entire renovation process, from initial assessment and securing government aid like MaPrimeRénov' to coordinating the work with certified technicians. After six years of self-financed growth, Hello Watt raised its first funding round of €12 million in November 2023 from BNP Paribas Solar Impulse Venture Fund and Starquest Capital to accelerate its expansion. This capital is intended to support further technological development, brand investment, and international growth, starting with Spain.
