Investors
Vassilis TziokasVenture PartnerBig Pi Ventures
Big Pi publishes a firm-wide equity-ticket range of €0.5M–€30M across its early-stage and growth funds; its early-stage Fund II described €1M–€3M lead investments. These are firm parameters, not Vassilis's personal allocation range.Blockchain InfrastructureZero-Knowledge ProofsEthereum
Aristos DoxiadisPartner EmeritusBig Pi Ventures
No current personal check range: Aristos is Partner Emeritus and an official 2025 biography says he is not involved with Big Pi's later funds. Big Pi's current platform range is €0.5M–€30M across funds, but should not be attributed to him.Deep TechResearch SpinoutsArtificial Intelligence

Firm-wide: Big Pi publishes equity tickets of €0.5M–€30M across its early-stage and growth funds.
