Run the Numbers

Running the Long Game in Growth Equity | Larry Contrella


Listen Later

In this episode of Run the Numbers, CJ Gustafson sits down with Larry Contrella, General Partner at JMI Equity, to unpack how JMI invests in software without financial engineering or roll-up strategies. Larry explains how the firm builds conviction through founder relationships, long-term partnership, and a product-and-brand-first view of durable growth. They discuss how JMI supports companies through scaling, why operating partners keep returning, and how underwriting looks different in mission-driven sectors like K–12 and nonprofit tech where customers are schools and communities, not Fortune 500s. Larry’s background as a competitive runner at Penn ties the conversation together with a clear ethos: patience, discipline, and playing the long game.
