John Anthony Smith
CSO and FounderJohn Anthony Smith
CSO and FounderChief Security Officer, John Anthony Smith, founded Conversant Group in July of 2009 as an outgrowth of his passion to cultivate people-focused business.
Engaged on numerous projects and consultations with companies both large and small throughout his 24-year career, John understands the unique challenges of conducting business on a human-centric level — its strategy, quality, and process. He especially understands the practice of law, as he has served law firms’ technological and business needs since 1998.
John started his IT career in 1994, at the age of 14, at Thompson Machinery Commerce Corporation of Lavergne, TN. While working with Thompson Machinery, John was involved with the initial rollout of multiple industry-leading technologies including: Citrix Winframe, IBM NetStation, Window NT 3.51, Windows NT 4.0, Windows NT Terminal Services Edition, remote access via Shiva, ISDN Internet, and WebSense.
During his time at Thompson Machinery, John founded his first company, Computech, in 1996. In 2002, he founded his second company, NetAlliant Technologies, which he sold in 2008.
In 2009, he founded Conversant Group, a technology conglomerate based in Chattanooga, Tennessee, serving clients across North America.
John studied Computer Science at the University of Tennessee at Chattanooga, and holds a degree in Organizational Management from Covenant College, Lookout Mountain, Georgia.
Mark Grazman
CEO and Co-FounderMark Grazman
CEO and Co-FounderCEO Mark Grazman is a successful entrepreneur and venture capitalist with a track record of launching, scaling, and leading successful companies. Most recently, Mark was the CEO of an email security company named MessageControl where he led the organization through a successful exit to Mimecast (NASDAQ: MIME).
Mark’s commitment to driving growth as a leader, board member, and advisor has given him the experience (and grey hair) to build a culture of excellence while rapidly scaling companies. From his transformational tenure leading strategy and technology for CBIZ (NYSE: CBIZ), launching Banque Nationale de Paris’s emerging markets private equity group to his entrepreneurial success as the founder of an internet company in Europe – Mark has an impressive track record of success and innovation.
Mark first met John Anthony and the Conversant Group during his tenure at MessageControl where John was an early adopter, reseller, and eventually an investor. John made it clear back then he was investing in Mark and started recruiting him almost immediately to join him in leading Conversant Group to drive growth, strategy, and culture. If you get them both in a meeting, be careful – they both have a lot to say!
Mark graduated in 1994 from Duke University and was invited back as an adjunct lecturer in the Public Policy Department years later. Throughout his distinguished career, Mark most prides himself on giving great opportunities to the people he has worked with, the teams he has built, and the leaders that have emerged from his mentorship.
