Alex Ehrlich's bio photo
Alex Ehrlich
Alex Ehrlich
Alex was raised in Long Beach NY by loving parents and an older sister who is still smarter than him. Uninspired by academics, but motivated by arts, causes and the need to pay bills, Alex worked part-time at Goldman Sachs before dropping out of college to spend the next 40 years having fun and making friends on Wall Street.

Alex built and led prime brokerage businesses throughout his career. He co-founded Goldman Sachs’ Prime Brokerage business in the early 1990s, and headed or co-headed that business in Europe and Asia, until he departed from that firm after 24 years. He went on to lead Prime Brokerage at UBS in London and New York for six years, after which he co-headed Prime Brokerage for a decade at Morgan Stanley, where he also oversaw the Listed Derivatives and Fund Administration businesses, served on the Equities and Securities Operating Committees, and chaired the Diversity Council of the Investment Bank. He left Wall Street with gratitude for his many mentors and friends, and recognition of how privileged he was to have had such opportunities.

During his years in London, Alex met the woman of his dreams on a blind date, and pursued her to Paris three days later. They’ve been married 30+ years, and have raised three sweet young men, all of whom are making the world a better place. They really want grandchildren.

“Talent is equally distributed, but opportunity is not. I founded Percapita with the aim of creating an equitable financial services firm that can play a role in addressing America’s unsustainable income inequality. Percapita is the product of lessons learned in banks, restaurant kitchens, basketball courts, shelters, and every place where people work to build better lives for their families.”

Aliah Greene
As a child, whenever told she had three wishes, Aliah's third wish was always for three more wishes. It was a way to continuously expand the realm of the possible in a framework designed to limit. Through a 20+ year career in finance, Aliah has been guided by three rules to do the same in her work. The first: Questions carry more power than answers. The second, which she learned from her son: Practice makes progress. The third is from the great Arthur Ashe: “Start where you are. Use what you have. Do what you can.”

As Percapita’s Chief Operating Officer, Aliah brings her experience working across risk management, treasury, and financial control at Morgan Stanley, most recently as a Managing Director and Head of Enterprise Risk and Analytics for the Wealth Management division and the Private Bank. More than that, Aliah brings the insights and passion gained from living the problem at the heart of Percapita’s work—and a commitment to all the communities still grappling with its challenges.

"Despite the substantial challenges my family has faced, I’ve been fortunate enough to be given access, opportunities, and systems of support that allowed years of hard work to eventually lead to financial health for us. Being part of Percapita gives me a chance, first, to help others now trying to overcome those same challenges and, hopefully, eventually, to help remove them entirely."

“When people lack access to financial services that so many of us take for granted, they lose a part of their dignity. At Percapita, we want to change that in a big way, and for a whole lot of people.”
