John Viglione, Former Senior Vice President, Vertex, Inc.

Before his retirement, John Viglione was the senior vice president of Vertex Inc., a public software and SaaS company located in the suburbs of Philadelphia, and was responsible for the strategic and operational alignment of the company. Having initially joined Vertex as its chief technology officer to complete the introduction of its then early market client/server offerings, John led efforts to architect its next-generation global transactional system known today as Vertex Indirect Tax O Series®, an on-premises, private-cloud and public-cloud platform solution. John was a member of the company's executive committee and strategy incubation board, which sponsored incubation investment in new and emerging business and technology ventures. He was also a member of the executive IPO sub-team to bring the company public and was responsible for the development of various industry models and market intelligence. John is active in the technology and industry analyst community associated with the global technology eco-systems, and he is responsible for business development and partner ventures.

Today John spends his time as an active board member of various technology companies. He is also an active member of the advisory board for Penn State University’s College of Information Sciences and Technology, his alma mater.
