The rules of finance aren't laws of nature. They are choices.

With a foreword by Kate Raworth, author of Doughnut Economics

Brave New Capital by Aunnie Patton Power and Erinch Sahan, foreword by Kate Raworth

We changed the mission statement on the cover page. We never rewrote the story underneath.

If you've spent time in impact investing, you've felt it. That nagging feeling that something isn't quite right. The intentions are real, the capital is flowing, and yet the funds we've built to deploy it look almost identical to the ones designed decades ago for entirely different purposes.

Brave New Capital is about the people who are rewriting it. Across the globe, a generation of pioneers looked at the machine they'd inherited, understood it completely, and chose to build something else: indigenous-led outcomes funds, steward-owned management companies, neighbourhoods that own the housing they live in, funds with no carried interest or end date at all.

This is not a book of theory or critique. It's a field guide to what these pioneers actually built: how they redesigned ownership, power, structure, and incentives, what it cost them, and what becomes possible when capital is designed around the people closest to the problem.

The rules of finance were never laws of nature. They were design choices. This is the story of the people choosing differently and an invitation to join them.

What's inside

Real vehicles. Real capital. Real markets.

Brave New Capital takes you inside the work of pioneers who rebuilt finance from the structure up. Among them:

01

A fund that buys companies from retiring owners and hands them to the workers who built them.

Ownership
02

A neighbourhood that owns the housing its residents live in — and decides for itself what success looks like.

Ownership
03

A citizens' fund where 290 ordinary people vote on every investment. One person, one vote. No carried interest.

Power
04

An Indigenous-led fund where an elder assesses every deal across seven generations — three back, three forward.

Power
05

A fund owned entirely by a perpetual purpose trust, designed so its mission can never be sold.

Structure
06

A fund manager who eliminated carried interest, asking: why should managing other people's money make anyone a millionaire?

Incentives
i

Ownership

Who holds it — and who's been kept from it.

ii

Power

Who decides, and who defines what good looks like.

iii

Structure

The vehicle itself, redesigned from the ground up.

iv

Incentives

Who gets paid, for what, and why.

Why pre-order

Honestly? How far this book travels is up to you.

Every pre-order is a vote: it tells us, and the wider field, that there's real hunger for this.

Aunnie has been working on this book for over four years. Erinch joined just over a year ago. We're nearly ready to send it out into the world, but we haven't decided how.

This pre-sale is how we find out how much appetite there is. Strong demand opens doors: it's what we'd take to a publisher to win the kind of reach usually reserved for the few. Quieter demand, and we publish it ourselves. Either way, your copy is guaranteed and either way, we're keeping it affordable and accessible.

We're doing this to drive the kind of change we describe. Profits go into building the ecosystem these chapters describe, supporting the pioneers and communities redesigning capital from the inside out.

The foreword

A foreword by Kate Raworth

We're honoured that Kate Raworth — economist and author of the international bestseller Doughnut Economics — has written the foreword to Brave New Capital. Her work has reshaped how a generation thinks about what an economy is for. This book takes up that question where capital meets the people closest to the problem.

The authors

Aunnie Patton Power

Author of Adventure Finance · Founding Director, IFI

A reformed M&A banker who got out, moved to India to figure out what impact investing was all about, and has spent the fifteen years since trying to redesign how capital actually works. She's worked across five continents with funds, foundations, governments, and family offices. Her first book, Adventure Finance, has been read by tens of thousands and translated into four languages — that one about the instruments of innovative finance. Brave New Capital is about the vehicles that house them, the thing she's been (not so quietly) obsessed with ever since.

Erinch Sahan

Joseph Rowntree Foundation · ex-Doughnut Economics Action Lab

Has spent two decades redesigning business and finance from the inside — across companies, NGOs, and government, on four continents. He now invests a multi-hundred-million-pound endowment at the Joseph Rowntree Foundation toward a more just and equitable future. He has spent his career arguing that businesses and the capital behind them have to be redesigned together.

There's a brave new world of capital worth reading about.
