Biography

Born in 1970, Jeff Fagnan has established himself as a central figure in the venture capital ecosystem, particularly on the East Coast. He earned his B.S. summa cum laude from Merrimack College and an MBA from Harvard Business School. Fagnan began his career as an entrepreneur, co-founding several software companies, including one that was sold to a public company. This operational background provided him with a firsthand understanding of the challenges and opportunities faced by founders, a perspective he has leveraged throughout his venture capital career. Fagnan joined Atlas Venture in 2000, eventually becoming a partner. During his tenure at Atlas, he developed a reputation for identifying nascent market trends and backing visionary founders. Notable investments from this period include DataPower (acquired by IBM in 2005), Pegasystems (NASDAQ: PEGA), and Vertica (acquired by HP in 2011). In 2014, Fagnan, along with partners Fred Destin and Ryan Sweeney, spun out a portion of Atlas Venture's active portfolio to launch Accomplice. Accomplice quickly distinguished itself as a seed-focused firm committed to high-conviction investing and hands-on support for its portfolio companies. Under his leadership, Accomplice has continued Fagnan's track record of successful early-stage investments. Key investments by Fagnan through Accomplice include PillPack (acquired by Amazon for $753 million in 2018), DraftKings (NASDAQ: DKNG), and Carbon Black (acquired by VMWare for $2.1 billion in 2019). Beyond direct investments, Fagnan is a recognized advocate for the venture ecosystem, frequently sharing insights on company building, fundraising, and market dynamics.
