I. Brief Summary
An excellent primer on impact investing by Priya Parrish who is CIO at Impact Engine and teaches at Chicago Booth. She makes the case that you don't have to choose between returns and doing good and that the belief you do is the single biggest thing holding impact investing back. She highlights the field's messy parts: the jargon, the greenwashing, the ESG backlash.
II. Big Ideas
- Priya Parrish wants to drag impact investing out of the fog of jargon, hype, and political noise and show what it actually is: investing that intends, causes, and measures real-world good while still earning a return.
- The definition is the whole game. The GIIN's framing rests on three words: intention (an impact objective set at the outset), generate (your capital actually causes the impact – the technical term is additionality), and measurable. Miss any one and it isn't impact investing.
- This is what separates impact investing from ESG. ESG asks how environmental, social, and governance factors affect a company's value – a risk and materiality lens. It considers impact that would happen whether or not you invest. Impact investing demands a direct, intended effect from the investment itself.
- ESG became a victim of its own success – now a political lightning rod, a catch-all the loudest critics don't actually understand. In practice the sophisticated treat it as a risk-management tool, impact objective or not.
- The roots run through socially responsible investing: negative screens that kept “sin” industries out of portfolios – tobacco, alcohol, gambling, weapons, later fossil fuels. The UN's Who Cares Wins report (2004) put the ESG framing on the map; KLD's Domini 400 Social Index was an early “do-gooder S&P 500.”
- The field has a birthday. The Rockefeller Foundation convened ~40 practitioners at Bellagio in 2007, coined “impact investing,” and spun up the GIIN (led by Anthony Bugg-Levine) to define and measure it. Pioneers were already at work: Acumen (Jacqueline Novogratz), Grameen Bank (Muhammad Yunus), and DBL Partners' Bay Area Equity Fund, an early Tesla backer.
- Three reasons to do it, per the preface: it can enhance returns and lower risk; it is a more efficient way to reach social goals than leaning only on philanthropy and government; and it is emotionally rewarding to put your values and your dollars in harmony.
- The 5/95% problem. Foundations give away ~5% a year while the other 95% – the endowment – often funds the very problems the grants fight. The Gates Foundation held oil companies polluting the Niger Delta while its grants battled disease there; public pressure pushed it toward mission-aligned investing.
- Why now. Governments move too slowly, anxiety about climate and the economy cuts across every generation, and for the first time U.S. children are likely to end up worse off than their parents. Households hold more investable capital than they give away – so investing with intent is the closest thing to real leverage most people have.
- Divestment proved capital is a lever. The anti-apartheid movement – Hampshire College first, 155 endowments by 1988, plus cities, states, and countries – helped force U.S. sanctions and contributed to the fall of apartheid.
- Measurement is hard and still maturing. SASB mapped the financially material ESG factors across 77 industries (~7 each); SASB and the ISSB now sit under the IFRS Foundation. Impact spans every asset class and stage – VC, PE, debt, real estate, farms and forests, public companies – though the book centers on for-profit VC and PE.
- The honest caveat: impact investing is not the answer. We still need government, philanthropy, voters, and volunteers. It is about systems change – pointing the massive power of finance at our hardest problems. Not easy, not perfect, but underutilized and powerful.
