Technis, a Lausanne company that sells spatial and energy analytics for buildings, has acquired Konstl, a Geneva-area firm that installs sensors in buildings and collects their data over its own wireless network. Technis announced the deal on its blog on November 3, 2026, and Swiss startup news site Startupticker reported it the next day, saying Konstl was joining Technis with immediate effect.
Terms were not disclosed. Technis said the acquisition continues its strategy of growing by buying companies.
Konstl will now operate as "Konstl, a Technis company", and its brand will be folded into Technis over the coming months, with each step announced in advance. Existing clients keep their contacts, installations and contracts. Didier Bernaud and the Konstl team are joining Technis, where Bernaud becomes head of operations.
What Konstl built
Konstl started in 2017 as a Geneva initiative led by naxoo, and Konstl SA was incorporated in 2020 together with five long-established Swiss companies, according to Technis. Konstl's website lists naxoo SA, SEFA, SEIC, SEVJ and TRN (SIN) as its backers. The company did not disclose its founders, funding or headcount.
The company specialises in Internet of Things networks for buildings. It installs sensors, many of them measuring temperature and humidity, gathers their readings over its own LoRa radio network and hosts all of the data in Switzerland. Its services include remote meter reading, monitoring of technical installations, tracking of indoor comfort and monitoring of the heat consumption index (IDC).
Konstl's own website describes a wider range of uses. Its Konstl App pulls data from connected equipment such as boilers, meters, lift pumps and doors into one view, and the company also offers water and water-quality monitoring. Beyond property managers and utilities, it targets cantons and care homes, for which it offers remote patient monitoring with connected watches.
Its clients are property management firms, utilities and municipalities in French-speaking Switzerland. Konstl's website also promotes energy performance contracts that require no upfront investment, and a client case study reporting average energy savings of 15% in the 12 months after deployment.
“Swiss property owners need to measure and improve the performance of each of their buildings.”
Why Technis is buying
Technis uses computer vision on existing cameras to count and map people and vehicles, and combines that data with energy figures for buildings. Its website lists clients such as SWISS, SNCF, Nestlé and Bouygues, and offices in France, the United States, Saudi Arabia and Qatar in addition to its Lausanne headquarters.
According to Startupticker, the deal pairs Technis's energy optimisation expertise with Konstl's data collection and technical supervision, so that optimisation can be based on actual measurements of indoor comfort. The aim is to help Swiss property owners measure and cut energy use across their portfolios one building at a time. Startupticker noted that energy performance of buildings in Switzerland is now both a regulatory requirement and a financial priority for owners.
The two companies had already worked together, notably on the Realstone property portfolio. Wiktor Bourée, Technis's chief executive, said Konstl had been doing on the ground for years what Swiss owners now need, and that together the companies could move faster and go further in reducing energy consumption.
A run of deals for Technis
Konstl is not Technis's first acquisition. In a September 2026 profile of Bourée published on the Technis blog, the company said it had raised 21 million, without specifying the currency, and had bought two companies, Videtics in France and E-NNO in Switzerland. It also said it had 82 employees, more than 200 international clients and over 2,100 buildings fitted with its technology. In January 2026, Startupticker reported that Technis had bought a Geneva pioneer in building energy performance.
Bernaud said Konstl had always wanted simple, robust supervision for building professionals in western Switzerland, and that clients would keep the close relationship they have with his team while benefiting from the backing of a larger Swiss group.
