In public markets, financial advisors universally recommend diversification to avoid this risk. In private markets, founders, early employees, and early investors are structurally forced into extreme single-stock concentration - their equity cannot be easily sold, the company's prospects are opaque, and the holding period can extend a decade or more. Greg Brogger's data makes the risk concrete: only 38% of US Series C companies from 2010-2015 had produced shareholder value a decade later. An employee with 90% of their net worth in a single Series C company faces a 62% chance that the wealth never materializes. The typical Collective recommendation is to exchange 15-20% of shares to create a floor, preserving most upside while eliminating the all-or-nothing exposure.Smart contractSelf-executing code on a blockchain that enforces rules automatically when conditions are met — the compliance layer Fairmint embeds into equity.Social CapitalismThe investment philosophy dominant among Millennials and Gen Z: evaluating opportunities by social impact and mission alignment before financial returns. Inverts the traditional transactional investor sequence (returns first, mission secondary) — the younger generation asks 'what is the impact?' and 'why does this exist?' before asking 'what is the yield?' CJ Follini frames this as the defining capital allocation behavior of the generations inheriting the Great Wealth Transfer. His pragmatic corollary: companies that structure around mission-plus-profit (modeled on AARP, not OpenAI's muddled nonprofit-to-capped-profit conversion) will attract the most capital from the next generation of investors.
