Early life and academic career

Bill Janeway was born on May 3, 1943 in Manhattan, the second son of Elizabeth Janeway, author and critic, and Eliot Janeway, political economy columnist. He attended Trinity School in New York, from which he graduated as valedictorian of the class of 1961, and Princeton University, from which he graduated as valedictorian of the class of 1965. He received a Marshall Scholarship to the University of Cambridge, where he received a Ph.D. in economics in 1971. His doctoral thesis on "The Economic Policies of the Labour Government of 1929-1931" was supervised by Professor Lord Kahn.
Investment career
Investment banking:
In 1970, Janeway joined F. Eberstadt & Co., Inc., the investment-banking firm that was founded by Ferdinand Eberstadt. In 1979, he became director of corporate finance. In 1985, F. Eberstadt was acquired by Robert Fleming & Co., the London merchant bank and investment management firm. Janeway served as director of corporate finance of the resulting American subsidiary, Eberstadt Fleming & Co., Inc., until 1988.
Venture capital:
Janeway joined Warburg Pincus, the private equity firm, in 1988 as head of its high technology investment team. The firm’s high-tech investments through the 1990s centered on information and communications technology, and, after 1991, increasingly focused on enterprise software.
In 1992, the firm funded the launch of OpenVision Technologies, which subsequently merged with VERITAS Software in 1996. In 1999, Warburg Pincus also was the founder and sole investor in BEA Systems. Warburg Pincus eventually distributed its positions in both companies to its limited partners, realizing total returns of $750 million in VERITAS shares and $6.5 billion in BEA shares on investments in each of approximately $50 million.
In 2006, Janeway retired as a Vice Chairman of Warburg Pincus. He remains a senior advisor.
Recent research

Work on innovation
Janeway re-engaged with academic economics through a friendship with Hyman Minsky that began in the mid-1980s. Janeway’s article, "Doing Capitalism: Notes on the Practice of Venture Capitalism," presented at the annual meeting of The Association for Evolutionary Economics in December 1985, was written at Minsky’s behest.
