Thermosphr

Thermosphr is a Berlin-based software company developing an end-to-end solution for thermal management of commercial buildings. Its product combines a plug-and-play gateway said to be compatible with any building management system (BMS), a thermal modelling and prediction layer, and real-time remote control of heating, ventilation and air conditioning (HVAC) equipment. The company describes the offering as an operating system for thermal management, built on proprietary technology derived from research in thermal optimisation and data science that simulates and predicts a building's thermal behaviour and then adjusts equipment settings for energy and cost efficiency.

The software is marketed across a wide range of asset classes, including offices and high-rise buildings, retail and shopping centres, hospitality, public buildings, transport hubs, logistics and temperature-controlled warehouses, healthcare facilities, and entertainment venues. Stated capabilities include arbitrage on energy tariff variations and smart grid management, continuous adaptation to weather conditions, air quality and pressure regulation, and 24/7 technical support for on-site technicians. The company positions the solution as a way to bring portfolios into line with current regulations and to increase asset value.

Thermosphr was founded in 2020 by Nicolas Le Borgne (CEO) and Dr. Ing. Mark Aaron Chan (CTO). Beyond the founders, the published team includes a Director of Operations, a Process & Product Lead, a Head of Sales for France, a Chief of Staff, an MPC (model predictive control) specialist, a software engineering lead, Python and data engineers, and BMS and HVAC specialists, with backgrounds cited at Siemens, VINCI Facilities, BMW Group, GE Global Research and NASA. Third-party data lists the company at 11-20 employees, headquartered at Methfesselstraße 43, Berlin.

Founding story

According to the company's About Us page, co-founders Mark Aaron Chan and Nicolas Le Borgne met in Berlin in 2020 at Entrepreneur First. Chan had spent his career in thermal management research and engineering at the National University of Singapore, NASA, General Electric and BMW, and sought to apply that expertise to a mission-driven venture; Le Borgne had held C-level roles (CEO and CFO) at startups and led business development and business intelligence at the real estate platform Lamudi, after earlier work as a consultant at Arthur D. Little and auditor at Suez. They founded Thermosphr to combine thermal engineering expertise with B2B commercial scaling in the real estate sector.

Business model

Thermosphr sells a SaaS solution to owners and operators of commercial buildings. Third-party material states the software plugs into any BMS and is offered at no upfront cost, with the company's website advertising free set-up in one day and first results within six weeks, suggesting a subscription or performance-linked commercial arrangement rather than a capital purchase.

Software-as-a-service delivered on top of existing building management systems, marketed with no upfront cost and free installation; a third-party aggregator estimates annual revenue of approximately $1.63 million, though this is an estimate rather than a company-reported figure.

Traction

The company's website reports a cumulative 1,500,000 m2 of building area operated, 20 GWh of energy saved and 3,000 tonnes of CO2e emissions avoided, alongside headline claims of up to 40% cost savings. Customer testimonials cite over 30% savings at a Veolia property within a month of activation and over 39% HVAC energy bill savings at Westfield Rosny 2. A third-party aggregator estimates annual revenue of about $1.63 million and 11-20 employees. As of the November 2021 pre-seed announcement the company had not yet commercially launched.

Latest developments

A third-party funding aggregator records a $3.2 million funding event dated 2024-02-06, bringing recorded total funding to $3.2 million across two rounds; this figure is not corroborated by a primary source or press announcement in the material reviewed. The company website, copyright-dated 2024, presents multiple deployed reference customers and cumulative savings figures, indicating the product is in commercial operation.
