Meet Sig Mosley

Today we’d like to introduce you to Sig Mosley.

Hi Sig, we’re thrilled to have a chance to learn your story today. So, before we get into specifics, maybe you can briefly walk us through how you got to where you are today?
I received my BBA from Emory University in 1968. In 1969, I joined MSA in Atlanta and worked there until we sold the company in early 1990. Shortly thereafter, I went to work for the Chairman of the company, John Imlay. I ran his family office and his family foundation and as a part of his investing, we did angel investing in early-stage technology companies, primarily in the Atlanta area. Over a 20 years period, we did 122 investments. In 2012, I created Mosley Ventures, an early-stage venture founded, raising 31.6 million dollars and doing 23 deals. In 2019, I joined Zane Venture Fund as a venture partner and served on the investment committee and became an advisor to Silicon Road Ventures.

We all face challenges, but looking back would you describe it as a relatively smooth road?
MSA went thru bankruptcy in 1970 and reduced the workforce from 800 to approximately 45. In addition, there was an attempted takeover of MSA in 1988. Raising Mosley Ventures took approximately two years.

As you know, we’re big fans of you and your work. For our readers who might not be as familiar what can you tell them about what you do?
While at MSA, I served as Vice President, Secretary and Treasurer. I handled a number of financial and administrative functions. As an angel investor, I did due diligence on deals, wrote term sheets, assembled investors, and served on many boards of directors. As a venture capitalist, I continued the angel functions as well as managing the fund.

I am currently an EIR at the ATDC, Ga. Tech Tiger program, Emory Goizueta Business School, on the cybersecurity advisory board at Ga State University, member of the Creative Destruction Lab at Ga Tech, and on the board of directors of StartUp Atlanta.

I continue to serve as Vice Chairman of Imlay Investments, Treasurer and Director of the Imlay Foundation, chairman of GATV and am on the board of the Russell Innovation Center for Entrepreneurs.

Other notable achievements include:

I currently hold the record for the largest Southeast Venture deal with the $5.7 Billion acquisition of Tradex by Ariba.

I was inducted into the Georgia Technology Hall of Fame in 2007.

I received the John Imlay Leadership award from The Executive Roundtable in 2010.

I received the Lifetime Achievement award from TiE Atlanta in 2011.

I was the 2012 Speaker of the Year Ward recipient from Emory Pelham Education Foundation.

I was chosen as one of the Georgia Titan 100 in 2022.

I am widely regarded as “The Godfather of Angel Investing’’ a title I earned as president of Imlay Investments.

Additionally, I have had two awards named for me:   TechBridge – Sig Mosley Entrepreneurial Leader Award and The ]] The Siggie Awards (, an event honoring the early-stage investors helping to grow Atlanta’s entrepreneurial ecosystem Awards recognize some of the unsung heroes in the Atlanta startup community: early-stage investors.
