    Signal Lake focuses on early stage investments in the broadband telecom and networking infrastructure industries. The firm seeks to fill the funding gap between angel funding and major venture capital firms by investing $100K to $100 million in world class technical teams that have developed highly innovative intellectual property that can be turned into a product line, resulting in a sustainable competitive advantage. Signal primarily focuses on companies in the Northeastern U.S., but is globally opportunistic. Signal Lake was founded in 1998 and is based in Westport, Connecticut with an additional office in Boston, MA. Signal Lake first raised a $25 million fund in 1999, and then raised a second fund totaling $35 million the following year. Those efforts were followed up by a $45 million 'Signal Lake Side Fund' in 2003 and a $23.5 million 'Signal Lake Side Fund 2.' The firm raised a 2009 fund of $150M.
