I have spent over two and a half decades working with entrepreneurial, venture-backed businesses. I have had the great pleasure of working with some of the most reputable venture firms and venture partners in the industry. Throughout those experiences, I have found that venture firms, while very committed to their portfolio companies, are not well equipped to provide the operational support that can truly help companies and management teams scale.

OpenView has “cracked the code” on providing the resources and services that expansion stage software companies need to grow into market dominant positions. For me, this is the fun part. OpenView gives me a platform from which I can leverage the lessons I have learned and skills I have developed as an operating executive to help our portfolio companies succeed in their markets.

Jim brings over 25 years of experience growing and managing cutting-edge technology businesses. As an operating executive, his career includes building highly successful organizations, bringing businesses to scale, IPOs, and a multi-billion-dollar exit. Jim is passionate about entrepreneurship and helping to build successful enterprises around exciting market opportunities. Jim currently serves on a range corporate boards from innovative startups, to fast growth pre-IPO companies, to publicly traded companies. He is a Trustee at Worcester Polytechnic Institute (WPI) and co-chair of WPI’s initiative in innovation and entrepreneurship as well as a lecturer in entrepreneurship at MIT’s Sloan School.

Jim previously served as President and CEO of data warehousing and analytics company Netezza. Throughout his tenure at Netezza, Jim brought his passion for building great teams that deliver disruptive technology solutions to market. In 2007, Jim worked to take Netezza public, ultimately driving the nearly $2B acquisition of Netezza by IBM in 2010 — a transaction dubbed the most “disruptive acquisition” of 2010 by Information Week.

Jim also led Endeca’s early rise from tiny startup to the leading provider of innovative information access and delivery software solutions to the Global 2000. Endeca was acquired by Oracle in late 2011. Prior to Endeca and Netezza, he served at PTC as an Executive Vice President and General Manager. Over the course of his 11-year tenure, he had the opportunity to manage roles across nearly every facet of that organization, helping the company grow from $11M to $1B in revenue.
