Portage Partners was founded in 2010 by Michael Leffell, former Deputy Executive Managing Member of Davidson Kempner, as a family office focused on compounding and diversifying wealth in private markets. Over the years, Portage expanded to include a select group of partners and senior executives at large-scale alternative investment firms. In 2022, we evolved into 10 East, an investment firm focused on targeted exposures to private markets across private credit, real estate, private equity.
