Investor at Castle Island Ventures
Check size: No current first-party ticket range is published. Castle Island describes an early-stage mandate around public-blockchain infrastructure and applications; no personal range or unilateral authority is claimed for Henry.
Henry brings data science and public-equity research to early-stage public-blockchain investing. His visible work concentrates on empirical stablecoin adoption and the health of DeFi markets: how collateral, incentives, risk curators, security and native-token value evolve as onchain finance shifts from subsidy-driven experimentation toward sustainable financial infrastructure.
Bring a rigorous data room. Show cohort, volume and revenue quality; distinguish organic usage from incentives; map collateral, oracle, curator and counterparty exposure; provide audits and incident response; and explain exactly where the protocol or company captures value. For applications, quantify why a public blockchain improves distribution, settlement or trust.
Inferred from his research and interviews: teams that can support claims with clean transaction or operating data, financial primitives with real user demand, sustainable incentive design, transparent risk, credible security practices and products whose economics survive declining subsidies or changing interest-rate environments.
Inferred: vanity metrics without cohort or revenue evidence, unsustainable liquidity incentives, opaque collateral and leverage, protocols whose native token has no credible value path, avoidable smart-contract or counterparty risks, and blockchain products that do not improve a financial or enterprise workflow.
Separate subsidized volume and deposited capital from retained users, recurring transactions, fees and durable demand.
Evaluate smart contracts, collateral, leverage, oracles, curators, counterparties and governance as an interconnected system rather than independent checkboxes.
Trace how protocol usage produces cash flow, security demand or other defensible value for a native token instead of assuming adoption automatically accrues to it.
Onchain and market data show stablecoins serving as practical dollar access, savings and payments infrastructure across emerging economies.
