Healthcare Infrastructure

First Round Capital

Check: First Round's published firm-wide initial checks are typically $1M–$7M, averaging about $3.5M; it has participated in rounds from $100K to $20M. No personal range is published for Brett.

Brett studies how thousands of small choices compound into an exceptional company. He backs very early builders with contrarian insight and an outlier capability, then works at the decision level rather than prescribing the finished product. His disclosed investments—Clay, Stedi, and Persona—show an interest in foundational B2B workflows: flexible go-to-market tooling, healthcare eligibility and claims APIs, and identity verification.

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.

Northzone (Web3)

Check: Not publicly disclosed. Northzone states that the firm invests from Seed through Growth and can remain a partner through pre-IPO; Wendy's current profile labels her personal focus as Early and says she likes to work with founders from as early as seed.

Wendy backs companies that change consumer behavior and expand the economic pie by capturing neglected externalities. She studies technology through people and behavior change, looking for a valuable position in a shifting value chain and a product capable of profound systemic change. Her hypothesis-led process separates factual and emotional evidence, makes assumptions explicit, challenges them through diligence, and still requires a differentiated leap of faith about fund-returning potential.
