In this episode of More MPE, hosts Ray Horton and Sandi Wright speak with Ron Gonen ’04, founder and CEO of Closed Loop Partners, a New York-based investment firm composed of venture capital, growth equity, private equity, project finance, and an innovation center focused on building the circular economy.

During this engaging interview, we discuss Gonen’s career trajectory, and he offers lessons on the transferability of leadership skills across different sectors, from entrepreneurship to government and finance. He stresses the importance of adaptability in leadership styles, particularly in motivating teams across various environments. His experience in the New York City Sanitation Department as deputy commissioner of sanitation, recycling and sustainability taught him valuable lessons about executing for leadership and maintaining high standards of professionalism.

Gonen's interview provides valuable insights for current and future Business School students. He emphasizes the importance of having a clear vision and purpose when pursuing an MBA, advising students to tailor their education to their professional goals. Gonen's own experience at Columbia Business School demonstrates how he leveraged the School's resources, including the Greenhouse Program and Lang Fund, to develop and launch his first venture, RecycleBank. He highlights the significance of sales and HR skills, which he believes are often overlooked in top-tier MBA programs but are crucial for business success.

For aspiring entrepreneurs, Gonen advises complete commitment to the venture, cautioning against considering other options if truly dedicated to starting a business. He also emphasizes the importance of learning from failures and quickly adapting those lessons to future ventures. For those interested in impact-focused careers, Gonen suggests identifying and maximizing specific skill sets that can complement entrepreneurial ventures. Throughout the interview, Gonen's story underscores the potential for combining social impact with financial success, challenging the notion that these goals are mutually exclusive.

In this episode of More MPE, hosts Ray Horton and Sandi Wright speak with Justine Zinkin ’02, CEO of Neighborhood Trust Financial Partners, a national social enterprise providing financial services to low-income workers. Born and raised on New York's Upper West Side, Zinkin’s journey into social enterprise was influenced by her family's academic background and her parents' diverse experiences.

Zinkin joined Neighborhood Trust directly after graduating from Columbia Business School in 2002, initially leading two separate but related organizations: Neighborhood Trust Federal Credit Union and Credit Where Credit Is Due. What she didn’t know at the time is that she was inheriting two nearly insolvent organizations. Fortunately, she was able to turn things around by applying some of the things she learned in business school, like turnaround management.

Neighborhood Trust has changed a great deal under Zinkin’s leadership, evolving from a local nonprofit financed entirely by donations to a national organization that earns 25 percent of its revenues by selling financial consulting services to other organizations. Her growth plans see the Trust financed almost entirely by earned income, with donations limited to serving the organization’s research needs.

Looking ahead, Justine discusses the challenges facing Neighborhood Trust, including potential changes in consumer financial protections that would threaten the Trust’s record of expanding the financial inclusion and empowerment of low-income workers. She closes by encouraging MBA students to pursue social enterprise careers, emphasizing the rewarding nature of applying business skills to solve intractable social problems.
