In January 2000, Neil Gagnon, Brian Gagnon, Maureen Drew and Susan DuMont left Gilder, Gagnon, Howe & Co. to form Gagnon Securities LLC. The founding team had a stated goal of creating a unique environment where group participation and collaborative research would be the foundation for managing money on both a long-only and a hedged basis. Since then, our management team has successfully applied this approach to investing on behalf of our clients.
