Make buildings more connected, so others can operate them better.

Buildings in the EU are responsible for 40% of our energy consumption and 36% of greenhouse gas emissions. 

At Wattsense, we believe that to reduce those hard-hitting numbers and positively change our environment, we must bring technology, mostly reserved for new or large facilities, to smaller and medium-sized buildings. 

Wattsense gives property owners the power to make their buildings more sustainable.

We simplify the technical management of buildings so that owners and managers can optimize energy efficiency, maintenance, and comfort.

At Wattsense, we want to solve one of the biggest problems for the property sector, digitally transforming existing buildings

A bit of history …


The internet has profoundly transformed the world economy, and still, the vast majority of building assets are disconnected and underperforming, causing deficiencies for occupants, service providers, and owners. On a mission to make buildings more efficient and open to new integrations, Louis Vermorel founded Wattsense.


Wattsense successfully raises its first round of funding, amounting to €730,000. It moves into new offices and celebrates its first anniversary with a growing team. 


Nothing stops us! Wattsense raised a second round of funding, this time for 2.3 million euros.


A significant year for Wattsense, as it marks its acquisition by Siemens Smart Infrastructure to boost IoT systems for small and medium buildings.


Wattsense continues to develop its product in autonomy, presenting its new visual identity and welcoming its 30th team member.
