Greenfield CapitalCheck size: Not publicly disclosed. Greenfield has led and joined pre-seed, seed, and Series A rounds, but public round sizes are not personal or firm check sizes.
Gleb leads Greenfield's DeFi work, combining protocol research, infrastructure operating experience, and deal execution. His current research emphasizes capital-efficient and safer liquidity architecture, intent-based execution, MEV and sequencing, and go-to-market systems that convert speculative launch capital into durable protocol use. Greenfield's broader mandate is to back early developer teams building an open, decentralized, and robust web across private, public, and liquid opportunities.
Novel DeFi primitives that materially improve capital efficiency or risk, infrastructure that gives applications sovereignty over execution and fair MEV capture, and teams able to turn technical design into real liquidity and lasting use. His work favors early developer teams and protocols with credible architecture, aligned communities, and a path beyond incentive-only growth.
No personal pass list is public. His research identifies fragile patterns: pooled honeypots and persistently idle liquidity, launch TVL concentrated in mercenary whales, long delays that dilute early users, complex contracts used before they are necessary, incentive programs without real utility, and narratives unsupported by an ecosystem ready to retain capital.
Lead with the protocol primitive and the measurable inefficiency it fixes. Map custody, approvals, atomicity, trust assumptions, MEV, counterparty and smart-contract risk; explain who supplies liquidity and why; show how initial capital arrives, what converts it into durable use, and what remains after incentives end. For agentic or intent systems, make execution sovereignty, ordering, settlement, and value capture explicit.
Evaluate whether liquidity can remain under user custody and be accessed just in time under revocable constraints, while accounting for approvals, solver incentives, liveness, censorship, price risk, and discoverability.
Separate launch-day trust and liquidity tactics from long-term retention; test whether real product utility, ecosystem readiness, aligned incentives, and broad users will remain after points or airdrops end.
Keeping liquidity in wallets and granting constrained execution access only when needed can improve capital efficiency, reduce pooled-contract systemic risk, and unlock risk-aware capital.
Protocol launches must coordinate trust, attention, and liquidity, then convert mercenary inflows into embedded utility, ecosystem readiness, and durable community participation.
Autonomous onchain agents need application-controlled sequencing infrastructure to order transactions, capture MEV fairly, and create machine-native economic primitives.

Gleb joined Greenfield in early 2021 and was promoted to Principal in 2022 after driving DeFi investments including Zharta and Flowty and working on Unbound Nation, Immortal Game, EtherMail, and Q. Previously he was Product Owner of Deutsche Telekom T-Systems' Staking as a Service unit, among the first enterprise efforts in staking and validation. He has followed DeFi as an analyst and researcher since its early years and earned a BSc in International Business from ESB Reutlingen.
