Caeli Energie raises €2.1M pre-seed for its low carbon air conditioner

Linksium is delighted with Caeli Energie's €2.1 millions pre-seed financing round. The Alpine startup, co-founded and incubated by its TTO Linksium, is revolutionising the world of air conditioners thanks to its patented technology that guarantees summer thermal comfort in a building with very little environmental impact.


Caeli Energie is an industrial deeptech startup that designs and manufactures low-carbon air conditioning systems. The solution is different from conventional air conditioning systems because it doesn’t use polluting refrigerant, consumes 3 times less electricity for the same cooling power and doesn’t increase the urban heat island phenomenon. The innovation is based on a particularly compact and efficient evaporative cooler with a patented architecture. Its technological developments are carried out with various public research laboratories in the Auvergne Rhône Alpes Region: LOCIE (USMB/CNRS), LGP2 (Grenoble INP) and INSA (Lyon).

This pre-seed round will allow the financing of the deployment of proofs of concept in real conditions to finalise the products before their commercialisation. For this deployment, Caeli Energie was able to gather several investors around its entrepreneurial and technological project, including the Vinci Group, a true ally of its future development.

"Thanks to this first round of financing, we have been able to recruit key profiles that will enable us to approach the next quarters, focused on product development, with confidence and determination. We are not forgetting our scientific fundamentals, however, with new academic collaborations planned for this year to oo on optimising our systems," says Rémi Perony, CEO and founder of Caeli Energie.

The startup has also been selected as part of the Deeptech Alpes acceleration programme, which is led by Linksium. "We are delighted to continue supporting Caeli Energie in its development. The acceleration Deeptech Alpes programme will enable it, over 18 months, to structure itself and to reach a milestone with a view to the next round of financing planned for 2023", concludes Philippe Mattia, Director of Linksium's Business Equity division.


Based at the Grenoble Alpes site, Caéli Energie has 11 employees and aims to become a major French industrial player offering a proven, sustainable and efficient alternative to the dependence of Asian groups in fields of climate systems. The startup has been supported by Linksium since October 2019. It was detected via the Out of Labs Challenge by the SATT's Incubation Department and linked with the LOCIE laboratory of the University of Savoie Mont Blanc and the CNRS. The incubation phase enabled the team to structure the business model and led to the creation of Caeli Energie in December 2020. Also supported by the CSTB (Centre Scientifique et Technique du Bâtiment) , Caeli Energie meets the expectations of professionals in the sector and hopes to become a new standard in summer thermal comfort.
