BOSTON, MASS - Founders Mark Blaxill and Matthew Stack announce the establishment of XLP Capital in response to the growing industry need of comprehensive, value-driven technology investment, development, and advisory services. Headquartered in Boston, MA with offices in New York, NY, and the Berkshires, XLP takes an engineering-based, hands-on approach to strategic technology investment and advisory work. It applies sophisticated management science to a hands-on, deal-driven approach to technology investment. Whether via the application of high-throughput computational science techniques, rapid prototyping or advanced technology landscaping and analytics, XLP focuses on creating value and wealth through its technology investments. These investments take multiple forms, including venture investing, shareholder activism and corporate innovation programs.
History and Background
XLP traces its lineage to the competitive strategy disciplines pioneered by Bruce Henderson at The Boston Consulting Group (BCG). XLP co-founder Mark Blaxill worked and trained under Henderson while at BCG. Mark was an integral member of the BCG contingent that coined the term, “time-based competition.” He published articles on the ideas, but more importantly he pushed his BCG teams to apply these new strategy ideas inside of clients. Mark’s teams ran real-time experiments on the plant floor to improve quality even while they toured the world to document best-in-industry engineering practices. His unique blend of hands-on activism and leading edge theory earned him some of the best client relationships in the firm and an invitation to run the firms’ own strategy R&D in 1999.
Mark took his team out of BCG in 2007 to start 3LP Advisors, a firm focused on IP strategy development, patent transactions and IP-based investments. By 2014, this team had advised over $250M in technology transactions. While at 3LP, Mark co-authored The Invisible Edge: Taking Your Strategy to the Next Level Using Intellectual Property (Portfolio, 2009), which was named Best Strategy Book in 2009 by a leading business journal. He has been named one of “The World’s Leading IP Strategists” by IAM Magazine.
XLP’s other co-founder Matt Stack, is an experienced technology investor, having co-founded and invested in a wide variety of startups over the past decade, including a healthcare software startup, a small electronics company, an advanced composites design firm, and a semiconductor distribution company that traded high performance semiconductor chips between Shenzhen, Tokyo, and Tecate.
Currently Matt is the founding manager of the Lambda Prime Investment Incubator Fund, and the Chief Investment Officer of XLP’s technology activist fund, Devonshire Capital Fund I. Matt also runs the Stack Family Office based in Boston, MA and New York, NY. He is an experienced early and seed stage investor in high tech hardware and analytics companies with over $200M in completed deals, and serves as a technology advisor to a variety of institutions and family offices overseeing and directing over $500M. Over the past decade, Matt has acquired and developed a collection of minority interests in companies across North America ranging from small university spin outs to mid-sized industrial technology companies. Matt serves as an advisor to a number of privately held companies, where he manages and supervises technology and high performance computing investments. Matt has served as the Director of Computational Science at Mars Corporation and as a Partner at 3LP – a Boston-based elite Intellectual Property advisory firm.
