## Questions

### Who runs investment decisions at Leslie Ventures?

Mark Leslie serves as Managing Director and makes investment decisions personally. He is the former founding Chairman and CEO of Veritas Software, which sold to Symantec for $13.5 billion in 2004. Leslie's operating background in enterprise infrastructure informs his investment selection, and he frequently takes board seats in portfolio companies as part of his active oversight approach.

### Does Leslie Ventures commit to external venture funds or only invest directly?

Leslie Ventures invests primarily through direct equity positions, though the firm has co-invested alongside top-tier seed funds on specific opportunities. The firm's permanent-capital structure — fully proprietary with no outside LPs — means it is not a traditional fund-of-funds, and its direct investments often reflect Mark Leslie's personal operating experience and board involvement.

### Which sectors does Leslie Ventures prioritize?

Leslie Ventures focuses on enterprise technology, specifically data management, storage infrastructure, cybersecurity, and applied AI. These sectors mirror the domain expertise Mark Leslie developed as CEO of Veritas Software. The firm also has exposure to digital health and fintech through opportunistic early-stage investments.

### How is Leslie Ventures related to the Leslie Family Foundation?

The Leslie Family Foundation is the philanthropic vehicle of Mark and Debra Leslie, with sons Seth and Josh Leslie involved in its governance. While legally separate from Leslie Ventures, both entities are funded by the Veritas Software exit proceeds and share a common family governance structure. The foundation does not make venture investments.
