What Citron does
Citron (legal entity SAS GADS) is a French proptech company founded in 2011 and headquartered in Suresnes, in the Paris metropolitan area. The company provides a Big Data and IoT-based energy management platform — branded Citron® — that collects, visualizes, analyzes, and acts on building energy consumption data for enterprise, public-sector, landlord, and real estate investor clients. The platform integrates with connected equipment, building automation systems, ERP systems, and maintenance provider feeds, and is structured into four modules: Collect (data ingestion), Visualize (dashboards and reporting), Analyze (anomaly detection, drift modeling, site ranking), and Act (energy master plan, alerts, and action tracking). A complementary human "Energy Manager" consulting layer is provided to clients on top of the software subscription.
Citron monetizes primarily through annual SaaS subscriptions to the platform, with pricing customized by building portfolio size and module selection, plus professional services revenue from regulatory audit support, energy strategy consulting, and compliance assistance with French regulations (notably Décret Tertiaire, Décret BACS, ISO 50001, and ESG certifications such as BREEAM, HQE, and ISR). The company employs approximately 150 people and serves over 70,000 buildings in France, ingesting more than 10 million data points daily. In April 2023, Citron closed a €20 million equity financing round led by Eiffel Investment Group, Eiffel Essentiel, Entrepreneur Invest, and Bpifrance, with stated use of funds to expand the team to roughly 200 employees and accelerate product development. Distribution combines direct enterprise field sales with channel partnerships (e.g., Capitole Energie) and technology alliances (e.g., iQspot, GRTgaz).
