Sig Mosley is widely known as the “godfather of angel investing” in Atlanta, having served as former president of Imlay Investments and now as Managing Partner of his own fund, Mosley Ventures [1][3][5]. He focuses on early-stage technology startups, primarily in seed and early rounds, with a thesis centered on B2B software, cybersecurity, health IT, mobility, and big data in the Southeast, especially Atlanta [3][7]. While specific check sizes and lead/follow behavior are not publicly detailed, Mosley emphasizes nurturing entrepreneurs alongside funding them and remains actively involved with his companies [3]. His notable portfolio includes Tradex, which was acquired by Ariba for $5.7 billion, as well as software companies Knowlagent and Synchrologic [1][7]. Over his career since 1990, he has invested in more than 120 to 165 startups with 82 to 106 exits, reflecting a high success rate compared to typical venture failure rates [1][3][8]. Mosley does not appear to have published distinctive public writing, but his patient, affable, and firm approach to investing is frequently highlighted in interviews and profiles [3][8].
