Macks Managed Investments

Larry Macks and Josh Fidler sit at the top of the two primary investment vehicles. Macks leads Chesapeake Realty Partners as Co-Chairman and CEO, focusing on Mid-Atlantic real estate development. Fidler is a Founding Partner of Boulder Ventures, which handles early-stage venture commitments. Philip Warsal manages the family office itself as Executive Vice President. The structure suggests capital allocation decisions are made within each entity's leadership team rather than by a single family office CIO.

Boulder Ventures, the family's venture arm, sources through traditional venture networks in technology hubs. The real estate portfolio relies on longstanding relationships in Maryland's development and construction community, anchored by Larry Macks's tenure as president of the Baltimore County chapter of the Homebuilder's Association of Maryland. The family office does not publicly operate a centralized deal-sourcing platform, and flow likely arrives through the separate pipelines of each entity.

It operates as both. The Macks family invests through two distinct platforms — Chesapeake Realty Partners for real estate and Boulder Ventures for venture capital — while maintaining a centralized family office led by Philip Warsal. This hybrid structure means the family deploys capital both like a traditional venture GP and like a direct real estate operator, with the office managing overlapping governance, tax, and philanthropic functions.

Boulder Ventures is itself a venture capital firm that raises outside LP capital alongside the family's commitment, suggesting the family acts as an anchor LP in the fund while also benefiting from direct co-investment exposure. Chesapeake Realty Partners invests directly in ground-up development and existing assets across the Mid-Atlantic. The family office does not publicly disclose a fund-of-funds program or commitments to external managers.

The wealth originates with Morton J. Macks, who founded Macks Homes, a major homebuilder in the Baltimore region. That operating business generated the capital that later seeded Chesapeake Realty Partners and Boulder Ventures. The fortune now spans two generations, with Mort's children — Larry Macks, Genine Macks Fidler, and Martha Macks-Kahn — actively involved in the family's business and philanthropic enterprises.

Yes. The Louise D. & Morton J. Macks Family Foundation is the family's charitable vehicle, named for the founder and his wife. Genine Macks Fidler serves as President and Martha Macks-Kahn as Vice President. The foundation operates separately from Chesapeake Realty Partners and Boulder Ventures, maintaining a distinct governance structure focused on grantmaking rather than program-related investing.

The family's venture entity, Boulder Ventures, routinely syndicates rounds with other institutional venture firms. The family itself can co-invest through balance-sheet capital alongside the fund. For real estate, Chesapeake Realty Partners at times brings in joint-venture equity for larger ground-up projects, though the firm does not market itself as a co-investment syndicate.
