  1. Career Highlights
    Joe began his career in software technology sales for a multinational company where he quickly rose through the ranks into leadership roles that charged him with running a $80M business unit across North and South America. Subsequently, he was recruited by the CEO of a $7M start-up, INSOFT (which later merged with Netscape Communications), where he led the development of innovative sales and marketing models that poised INSOFT for growth and resulted in a significant valuation increase, from $21M to $180M. He opened the European and Asian Pacific markets and directed merger integration initiatives with Netscape.

    Joe continued his executive career at TrueSecure (CyberTrust), a $50M start-up provider of security solutions for Internet-connected organizations, which later became acquired by Verizon. At TrueSecure, Joe raised over $40M in four rounds of financing to fund the company’s development efforts, increased sales from $1M to $47M, and established subsidiaries in Japan, Brussels, and Hong Kong.

    Subsequently, Joe joined Consul Risk Management, a SoftBank backed company based in the Netherlands, as its COO and quickly advanced to serving as CEO and a Board Member. In his capacity as CEO, Joe increased Consul’s business value through growth of its novel technology, leading the company to achieve market leadership and ultimately positioning it for sale to IBM which resulted in a 500% increase in shareholder value. Thereafter, Joe joined Harmony Information Systems, Inc. (now WellSky), an underperforming venture-backed company, as its CEO and Board Member, earning it the Deloitte Fast 500 Technology Award, and establishing a positive exit to a Thoma Bravo-backed company for 5X its hold value.

    Most recently, Joe served as CEO and Board Member for Arxan Technologies (now Digital.AI), a TA Associates private equity-backed cybersecurity company that he helped pivot into a world-class enterprise sales and marketing organization and successful “rule of 40” business model. Joe led the organization through a period of meaningful growth, profitably generating tens of millions of annual recurring revenue with hundreds of enterprise customers worldwide, and ultimately to a successful sale to TPG Capital in July 2020.
