Shield Capital adds two venture partners

Shield Capital has appointed Michael A Brown and John “JJ” Jack as Venture Partners. Both will bring proprietary deal-flow to the firm and seasoned management, industry expertise, and go-to-market leadership to Shield’s portfolio companies.

Brown and Jack have built and scaled market-leading technology companies over thirty years. Their experience and networks will bolster Shield’s efforts to support company founders solving important problems in artificial intelligence, autonomy, cybersecurity, and space vital to commercial and government customers.

Brown most recently led the Defense Innovation Unit (DIU) since 2018 as its 3rd Director responsible for sourcing strategic technology advantage from America’s innovation ecosystem. His prior work as a Presidential Innovation Fellow helped catalyse the Foreign Investment Risk Review Modernisation Act, which provided expanded jurisdiction to the Committee on Foreign Investment in the United States (CFIUS). Prior to distinguished government service, Brown led Symantec Corporation as CEO, a global leader in cybersecurity and the world’s 10th largest software company. Brown previously served as Chairman and CEO of Quantum Corporation, a leader in the computer storage industry which he joined in 1984 and on whose Board of Directors he served from 1995 until 2014.

Jack has worked in the software industry in sales, marketing, and senior leadership and executive management. He served as CEO at Fortify Software (acquired by Hewlett Packard), CEO of Covalent (acquired by VMware), and COO at The Vantive (acquired by PeopleSoft). Jack has decades of expertise in scaling and growing software companies. He started his career at Sybase, eventually becoming their SVP of Sales.
