Asterion Ventures is an early-stage investment firm focused on systemic impact across Europe, with offices in Paris and Amsterdam and active venture partners in Brussels and Zurich. Impact-focused by design, Asterion backs founders tackling structural challenges across energy, industry, climate risk, health, and physical AI. In four years, Asterion has mobilized nearly €65M into 30 early-stage companies. Its current early-stage fund totals €50M, and Asterion is preparing a new €100M fund. Four portfolio companies are now scaling into Series A/B with top European funds, including Weefin, Spark Cleantech, Everdye, and one soon to be announced; one has already exited. Asterion’s edge lies in scale powered by people: a community of 900+ entrepreneurs and executives invest as business angels, representing roughly 50% of each round. They bring not only capital, but also operational experience, time, and hard-to-access networks. Beyond financing, Asterion has built dedicated programs for exited founders (Life After Exit), women investors (Invest Like a Woman), and entrepreneurial families (Immersion). Its LP base includes founders of French unicorns and European top impact companies such as Back Market, BlaBlaCar, and Too Good To Go, a few corporates and long-term family offices like Entheos, including prominent families from Northern France.

At WeMaintain, we believe smarter buildings start with the right people + tech. Founded in 2017 in Paris, we set out to fix what was broken in building operations: outdated processes, limited data, and a system that often overlooked the people who make buildings work.

Our product ecosystem supports every stakeholder: – An App built for engineers in the field – A customer platform for asset managers and building owners – A back-office system for operations teams – And Maximize, our independent IoT monitoring solution providing predictive insights across all equipment types, brands, and models. With this end-to-end approach, clients can optimize performance, ensure compliance, and make smarter decisions, backed by real-time data and transparent reporting. Today, we operate in France, the UK, Singapore, and Hong Kong, driven by the same mission that inspired us from day one: To empower the people behind the machines with smart tools and real autonomy, transforming traditional maintenance into seamless, data-driven operations. We’re not just maintaining buildings, were leading the building operation transformation.
