Planet A Ventures

Quick read

Planet A Ventures is a climate-focused VC, founded in 2020 and headquartered in Hamburg, Germany. It backs European green tech startups from pre-seed through Series A, deploying €500K–€5M checks across a €160M fund. What sets it apart is an in-house science team that runs life cycle assessments on every deal — scientists hold veto power if a startup's environmental impact can't be quantified.

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.
