Professional Journey

Hewitt led Exari, a contract lifecycle management provider, as President and CEO. In April 2019 Coupa Software, then Nasdaq-listed, agreed to buy Exari to extend its contract management capabilities into full lifecycle management: contract creation, clause management, negotiation and AI-based extraction of data from contract text. Announcing the deal, Hewitt said that “understanding contract exposure and opportunities is increasingly a board issue as companies struggle to effectively manage compliance and business risks”. Coupa completed the acquisition on 7 May 2019.

LinkSquares’ biography of him also lists roles as President and CEO of Aternity and as interim CEO of MindBridge Analytics and of Wagepoint. The sources read give no dates for these roles.

He also sat on the board of LinkSquares, another CLM vendor, whose Form D filings list him as a director in July 2021 and April 2022, when Vishal Sunak was President and CEO. On 10 March 2026 LinkSquares appointed him Interim Chief Executive Officer, effective immediately. Jump Capital co-founder and LinkSquares board member Mike McMahon cited “his success leading Exari combined with his dedication to LinkSquares” as giving the company continuity. Hewitt said LinkSquares was “uniquely positioned at the intersection of AI and legal technology”. The company describes him as a returning member of its board, and he continues to serve on it while acting as chief executive.
