Venture Partner at Big Pi Ventures
Check size: 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.
Vassilis brings a blockchain ecosystem and go-to-market lens to Big Pi's technology investing. His public work emphasizes the transition from crypto trading toward usable infrastructure: privacy-preserving institutional networks, interoperable bank deposits, Ethereum applications, zero-knowledge systems, stablecoins, and real-world financial workflows. This sits within Big Pi's broader preference for defensible technology, global markets, and teams that can translate technical invention into commercial products.
Show a hard technical advantage and the path from invention to distribution. For blockchain products, specify the user, trust model, privacy and compliance architecture, interoperability and settlement path, and why a chain is necessary. Bring evidence of developer or institutional demand, a globally relevant market, and a balanced team that can commercialize the technology.
Technically differentiated systems that solve a concrete coordination or privacy problem, products that can move from prototype to regulated production, teams combining deep engineering with business development, global market potential, and infrastructure that makes blockchains useful to institutions without sacrificing verifiability or interoperability.
Big Pi's published criteria reject technology without a defensible advantage, narrow markets, incomplete teams, and early inventions without a path to a useful marketable product. Vassilis's public commentary also implies caution around trading-only narratives, institutional products without privacy, and interoperability claims that ignore clearing and settlement. The latter are inferred signals, not a formal personal exclusion list.
Evaluate privacy, permissioning, compliance, data residency, neutral verification, interoperability, clearing, final settlement, uptime, and integration with existing institutional systems.
For deep technology, connect defensible invention and intellectual property to a specific buyer, usable product, business-development capability, scalable delivery, and a global market.
Distinguish messaging from actual interoperability by tracing redemption, issuance, netting, residual settlement, privacy boundaries, and the ultimate claim on each bank's balance sheet.
Tokenized bank deposits require private, neutral, verifiable clearing and settlement architecture; regulatory delay changes timing but does not remove the underlying institutional buildout.
