An inspiring read by a passionate trailblazer. Durreen Shahnaz shares her remarkable experiences with challenging the status quo, beating the odds, and fuelling change.
Slide Dr. Judith Rodin
Former President of the Rockefeller Foundation and Former President of the University of Pennsylvania
In this book, Durreen Shahnaz details her boundary-pushing experiences with candor, wisdom, and vivid storytelling. Documenting her journey from war-torn Bangladesh to the pinnacle of the financial markets, Durreen effectively weaves in the importance of finance in sustainable development and women empowerment. As President of the Rockefeller Foundation, which supported some of her groundbreaking early work in impact investing, I have seen the driving force of her passion and her intellect. This same passion flows through The Defiant Optimist™, inspiring women and girls and reminding them of the power they behold if they only dare to dream. She is a wonderful role model for girls and women everywhere.
Slide Antony Bugg-Levine
Co-Founder, Global Impact Investment Network
This book is a rare looking glass into what ‘impact investing’ really means on the ground, bridging the back streets to the Wall Streets of the world. Few are armed with the tenacity Durreen has, and even fewer go on to chart exceptional paths in creating impact for those the financial system leaves behind. I’m proud to have been a fellow pioneer in the movement, and this book reminds us that a revolutionary change starts from a small step. Let that step be “The Defiant Optimist™” and it will inspire you for miles to come.
Slide Ms. Claire Chiang
Co-founder, Banyan Tree Holdings
Read it and be inspired to make your journey of inclusion and sustainability. This book by Durreen Shahnaz is the silver lining to the challenging climate we live in today — be it vis-a-vis the environment, society, or economy and a reminder that within all of us, there is a defiant optimist who can make a change. There is an instant connection to her through her captivating stories and deep insights; this is the firestarter for our own journeys we never knew we needed. As a woman entrepreneur committed to creating sustainable and responsible growth for the company, I could relate to the struggles Durreen went through, and how one needs to persevere in our business journey in co-creating for the Greater Good. I applaud her vision, mission, and courage.
Slide Jed Emerson

There are few in our field who have been as steadfast and engaged in advancing a vision of finance with justice as has Durreen Shahnaz. The opportunity to learn from her journey and lessons in activism and financial innovation is not to be missed!
Slide Kathleen McCartney
President of Smith College
Durreen Shahnaz’s poignant account of her life’s journey, especially the courageous steps she has taken on her career path, highlight three key lessons: promoting women’s education and empowerment; advancing diversity, equity, and inclusion; and summoning the courage to identify sources of power. This memoir will inspire college students to embrace what Shahnaz calls the “defiant optimist” mindset, as they strive to create better futures for themselves and for the world.
Slide Professor Muhammad Yunus
Founder, Grameen Bank – Nobel Prize Winner, 2006
As the world pushes for gender equality and women’s representation in the global financial system, Durreen Shahnaz is one of the few who has rolled up her sleeves and done the work of lifting women up. With its compelling and intricate details, this book journeys the becoming of the defiant optimist and how it is with this spirit that Shahnaz goes on to change a system that works only for the 1%. It was touching for me to see how Grameen played a role in it all. The book is timely, necessary, and most importantly, empowering for all who want to create change, however small.
