Overview
Cleantech Venture Day Paris 2026 is structured as a focused investment and innovation event rather than a large-scale conference. Selected early-stage companies pitch their technologies to a curated audience of investors, corporates and other organisations, with the programme also providing opportunities for discussions, introductions and networking intended to lead to investment, pilots and commercial partnerships. The Paris edition has a particular focus on energy resilience and collaboration between Europe and the UK, with technology areas including:
Energy systems
Industrial water
Advanced materials
Deep-tech and engineering-led climate solutions
The organisers are particularly interested in technologies where scientific or engineering innovation provides a competitive advantage and where scaling requires more than software alone.
Attendance
The event is aimed particularly at climate-tech founders, investors, corporates and ecosystem partners. Applications are currently open for companies seeking to pitch in Paris, with eligible applicants including pre-seed, seed and Series A ventures from the UK, France, Belgium, the Netherlands and Germany.
