WaltR develops a technology that pairs space imagery with ground data and AI to identify, measure and map gaseous and particulate pollutant emissions from cities, industrial sites and airport or port infrastructures. The company says the new financing will support commercial growth in France and across Europe, while backing technical developments and an innovative R&D program. WaltR closed its first fundraising of €2 million in a round led by Groupe ADP with participation from Expension Ventures, Spacefounders France, Pays de la Loire Participation and Centrale innovation. The startup opened an office in Nantes in 2024 as part of its expansion. WaltR was founded in 2018 by Éric Pequignot as a spin-off of CNES and currently employs 20 people. The capital will be used to accompany commercial rollout and further technical and R&D work.
