James Earl Brown III

Founder & General Partner at Arena Growth Partners

Jim brings 20+ years of industry domain expertise and a successful investment track record in venture capital, angel investments, and private equity, as well as experience as a CEO and a director in several private companies. Jim was most notably a General Partner at Polaris Venture Partners, where he identified, led, and actively participated in investments in early-stage information technology companies, including enterprise software, telecommunications software, and technology-enabled businesses and platforms. Jim actively participated in developing firm strategy and in fundraising activities. During his tenure, Polaris grew from $85M to over $3B in assets under management (AUM). Representative investments include: Antenna Software (acquired by Pegasystems [NASDAQ: PEGA]); Avici Systems (NASDAQ: AVCI); Crimson Solutions (acquired by Experience, Inc.); Exchange.com (acquired by Amazon.com, Inc. [NASDAQ: AMZN]); InvisibleHand Networks; Linguateq (acquired by Sonus Networks [NASDAQ: SONS]); MarketXT (acquired by E-Trade [NYSE: ET]); and Watchfire (acquired by IBM [NYSE: IBM]). These companies represent over $10B in enterprise value and significant returns for Polaris investors.

Jim’s most notable investment was in Akamai Technologies (NASDAQ: AKAM), where Polaris was an initial first-round investor. Jim helped source the deal through his relationships with professors at M.I.T., and bonded with the technical founder, an M.I.T. Ph.D. student and former Tank Commander in the Israeli Army. Jim led Polaris’s investment, initially valued at ~$20M at the close of the Series A. The company went on to receive strategic investments from Cisco and Microsoft at ~$500M and ~$1B valuations, and subsequently went public to raise ~$234M of capital. Akamai was among the largest and most successful IPO’s in the Northeast, peaking at a market cap of ~$30B. Among Jim’s most noted contributions post-investment was his active role in identifying and recruiting several mid-senior level managers and leaders (known within Akamai as “Titans”) that helped rapidly scale the business to multiple Fortune 1,000 customers and partners across the globe.

Jim’s operating experience includes the roles of President & CEO, and as a director, at both InvisibleHand Networks and SparkPhone, Inc. Jim began his career as an investment banker and private equity associate with J.P. Morgan & Co., and J.P. Morgan Capital, providing equity capital and leveraged loan financing in support of acquisitions, investments, and recapitalizations for private equity firms and private companies. Jim’s career began with service to the nation as a Captain and Aviator in the United States Army with both the 2nd Infantry Division in Korea and the 101st Airborne Division.

Jim holds an MBA from Harvard Business School, where he was President of the student body; a JD from New York University School of Law, where he was an Associate Editor of the Law Review, a Root-Tilden Scholar, and an International Fellow; and a BS in Engineering and Political Science from the United States Military Academy at West Point, where he was a varsity athlete, selected as a Battalion Executive Officer his senior year, and where for four years he made the Dean’s List.
