Things about me

  • I believe curiosity is key to professional success and personal fulfillment. I love partnering with and learning from curious entrepreneurs.
  • I played golf competitively growing up and was the co-captain of the Columbia golf team.
  • Given the opportunity, I am happy to name the entire 1986 New York Mets roster, including the coaching staff.
  • Nate and I are pretty evenly matched in ping pong. A lot of our best business ideas come in the middle of very close matches.

Steve co-founded Growth Street Partners with Nate Grossman. Prior to Growth Street, Steve was a Partner at Mainsail Partners, a growth equity firm based in San Francisco. Steve has extensive experience investing in founder-owned software and technology-enabled services companies with specific experience in financial services, education, and supply chain markets. Steve was a Director of PayLease (sold to Francisco Partners), Netchemia (sold to PeopleAdmin), 3PL Central, Ncontracts, and nCourt. While a Director, three of the companies successfully completed add-on acquisitions: Netchemia-SchoolSpring, Ncontracts-Strohl, and 3PL Central-iTracker. Prior to Mainsail, Steve led deal sourcing for Vector Capital, a multi-billion dollar technology private equity firm, where he helped to source three platform investments. He began his career as an investment banker at Credit Suisse First Boston and Merrill Lynch. Steve earned a BA from Columbia University.

  • I am the third oldest of six siblings. At any given time one of us is almost definitely on a tennis court.
  • I got my master’s degree in Social Psychology. I love learning about how people make decisions and how seemingly small cues can have outsized impacts.
  • I believe strongly in the Growth Mindset. I want to work with entrepreneurs who are driven by learning.
  • I never lose to Steve in ping-pong.
