Investment thesis

Planet A backs European green tech startups from pre-seed to Series A that can demonstrate quantifiable positive impact across climate mitigation, waste reduction, resource savings, and biodiversity protection. Every investment passes a scientific veto gate — the in-house science team runs life cycle assessments and can block deals that don't meet impact thresholds.
