Building an Angel Investment Portfolio: Diversification and Follow On Strategy

A practitioner-level framework for building and managing an angel investment portfolio, for readers who already know what angel investing is and are ready to invest like a portfolio manager rather than a hobbyist. Goes beyond the basic power law story into quantifying it: how many startups you actually need, expected value math, check sizing and ownership targets, and return simulations. Covers real diversification strategy across sector, stage, geography and vintage, and treats correlation and concentration risk seriously. Devotes a full chapter to reserves and follow-on decisions, including how to actually exercise pro-rata rights and when to double down versus walk away. Closes with the operational side: tracking a portfolio, running periodic reviews, and managing exits across secondaries, M&A and IPOs. Built for experienced retail investors exploring alternatives, HNIs, and angel investors actively building out a portfolio, with Indian examples throughout including SEBI-registered angel funds, AIFs, and Indian syndicates.
