Christian Zimmermann

Partner and Chief Operating Officer

Greenfield Capital

Check: No personal check-size range is published. Greenfield invests across pre-seed through later stages, while Christian's stated responsibility is implementing investment decisions rather than owning a public personal allocation range.

Christian applies transaction, regulatory, and policy expertise to executing Greenfield's crypto investments. His work argues for clear decentralization standards, practical token tax treatment, open institutional access to digital assets, and privacy-preserving crypto infrastructure that reconciles public networks with legitimate personal and institutional confidentiality.

Felix Machart

Research Partner

Greenfield Capital

Check: No personal check-size range is published. Greenfield's venture mandate spans pre-seed through later stages; financing amounts in Felix's investment essays are company-round totals, not personal limits.

Felix uses research and market data to identify durable crypto infrastructure and distinguish fundamental adoption from speculation. His work favors protocols with measurable usage, revenue or value accrual; secure programmable ownership; credible governance; and infrastructure that connects decentralized finance with institutional and real-world assets.

Pre-seedHackathon to acceleratorInitial product sprint

Michael Rinko

Associate

Colosseum

Check: Colosseum's published accelerator investment is $250K pre-seed for accepted teams; it is a program-level standard, not Michael's personal discretionary check. Current materials say hackathon winners are interviewed and considered, with accepted teams receiving capital, mentorship and network access. Earlier official content described 7% terms; founders must verify the current instrument, percentage and token/equity structure.

Michael's lens combines markets research with Colosseum's tournament-style venture funnel: use global hackathons and four-week build sprints to observe which founders ship, learn and attract users before investing. He is interested in Solana products that exploit crypto-native primitives rather than append tokens to conventional software—especially futarchy and market-protected capital formation, tokenized cash-flowing assets, sophisticated trading tools, privacy-enabled settlement and AI-enabled onchain agents. He treats tokens as useful when distribution, user alignment, liquidity and governance matter, but recognizes that early public prices can distract pre-product teams and that long-horizon capital-intensive companies fit equity better.

Eterna Capital

Check: $250K–$1M indicated by current investor directories, with roughly $500K described as a sweet spot. Eterna's own live site confirms a global, early-stage mandate but does not publish a check range, so founders should verify current size, reserves, instrument and lead appetite directly. Eterna has publicly co-led at least one pre-seed round (Stoffel Labs).

Nassim invests where decentralized protocols, programmable value layers and AI-native infrastructure converge to reshape the internet. His work connects crypto's ownership and market primitives to broad economic utility: tokenization and stablecoins that improve access and liquidity, privacy-preserving computation that makes sensitive applications possible, authenticated data for AI and blockchain, and technical infrastructure capable of moving from inception through real products, sustainable business models and network-effect communities.

Vassilis Tziokas

Venture Partner

Big Pi Ventures

Check: 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.

Sebastian Blum

Founding Partner

88%

Greenfield Capital

Check: No personal check-size range is published. Greenfield's venture strategy invests from pre-seed through later rounds; its EUR 135 million Fund III size and portfolio financing totals are not Sebastian's personal check parameters.

Sebastian backs open, decentralized infrastructure that removes single points of failure and gives users and institutions resilient alternatives to concentrated cloud, communications, identity, and financial systems. His current thesis treats privacy, self-sovereign asset management, encrypted computation, and machine infrastructure as commercially important layers of European digital sovereignty rather than speculative crypto niches.

Claude Donzé

Principal

88%

Greenfield Capital

Check: No verified personal check-size range is published. Greenfield invests across private, public, and liquid crypto assets from pre-seed through later stages; disclosed Claude-led financings include Rebind's €1.6M pre-seed, Greenfield's co-lead in Layer3's $15M Series A, and Greenfield's lead in Self's $9M seed. Those round sizes are not Claude's personal allocation authority.

Claude leads Greenfield's consumer investing and backs crypto products that turn mature onchain rails into understandable, trusted consumer experiences. His published work focuses on mobile-native DeFi that hides operational complexity, engagement networks that verifiably connect protocols and users, and privacy-preserving identity that protects human participation as AI agents proliferate. He evaluates both private companies and liquid tokens through product-market fit, token value capture, team execution, macro structure, and network effects.

Greenfield Capital

Check: No personal check-size range is published. Greenfield's venture strategy spans pre-seed through later rounds; disclosed portfolio round totals are not Andrzej's personal allocation limits.

Andrzej brings an operator-CTO lens to Greenfield's crypto portfolio. His current published work emphasizes privacy as general-purpose infrastructure and backs decentralized encrypted computation that can make sensitive finance, healthcare, AI, and enterprise workloads usable without exposing raw data. His role is technical and portfolio-facing rather than publicly described as a conventional sourcing mandate.

Collider Ventures

Check: No reliable official current check range was found. Collider publicly describes itself as an early-stage Web3 investor and accepts pitches at invest@collider.vc; third-party directory estimates conflict, so founders should confirm current vehicle, stage and sizing directly.

Eylon connects two decentralization theses: crypto-native individual sovereignty that minimizes centralized authority through technology, and Web3 collective empowerment that democratizes ownership and access. In practice he looks for non-consensus early-stage infrastructure capable of moving capital formation, markets and digital ownership onchain while remaining alert to the new choke points, governance hierarchies and risk created by ostensibly permissionless systems.
