Matt VanVleet

CTO Matt Van Vleet

The eHumanize leadership team includes veteran product innovator and CTO Matt Van Vleet. Van Vleet brought two technology companies to market (including Pillar Technology, recently acquired by Accenture). Van Vleet brings a unique combination of technical development ingenuity and business entrepreneurship. He focuses on helping companies with leaders who are expert in their field launch platforms and companies that help scale their ideas and expertise.

As an investor and practitioner at Pillar Technology Van Vleet performed almost every role at the company before its eventual merger into Industry X.O, an emerging organization within Accenture Digital. As COO in its last few years, Matt was able to help Pillar scale over 30% per year and was instrumental to the VC capital raise and eventual merger with Accenture. In addition, as a Founder of Solstice Software, Van Vleet raised venture capital and eventually sold to Solstice Software from which it was subsequently purchased by IBM.
