Solen.co, founded in 2016, offers a technology platform to the real estate sector that quantifies a property's exposure to natural light and sunshine. The company's genesis traces back to a school project at HEC Paris, where founders Clément Henry, Enzo Laurent, and Thomas Tirtiaux developed an algorithm to measure sunlight on Parisian terraces. Recognizing that natural light is a top-three criterion for property buyers, they adapted their technology for the real estate market. Geoffroy De Boissieu is also listed as a co-founder.
The firm primarily serves real estate professionals, including agents, developers, and diagnosticians, by providing a tool to objectively validate and market a property's brightness. The business model is subscription-based, offering different tiers of access to their proprietary certification service. Revenue is generated by selling monthly subscriptions for a set number of light certificates, with packages tailored for individual agents, agencies, and large accounts. In 2021, Solen was acquired by the Septeo group to create synergies with Septeo's existing real estate technology solutions.
Solen's core product is a 'natural light certificate,' generated via a mobile application. Using a smartphone, an agent can perform a quick scan of a room, and within 24 hours, receive a detailed report. This certificate provides key metrics: the average daily hours of direct sunshine, the duration of sufficient natural light for activities like reading, and a comparison to the city's average brightness. The technology combines astrophysics to predict sun paths, optics adapted for smartphone lenses, augmented reality to guide the user, and artificial intelligence for image analysis. This provides a scientific measurement that can be used as a key selling point, helping agents secure exclusive mandates and sell properties faster. A free version of the app, Solen Live, allows users to visualize the sun's trajectory in real-time during a property visit.
