Alexie Holmberg

Alexie Stephen Holmberg is a Managing Director at Arena Strategic Advisors, a Fairfax, Virginia–based strategy and mergers-and-acquisitions consulting firm founded by Michael B. Kotarski. The firm works across growth strategy, M&A, and operational improvement, and staffs itself with people drawn from corporate leadership, top consulting firms, the U.S. military, and the U.S. intelligence community. Holmberg is one of three Managing Directors alongside Kotarski (Senior Managing Director/Founder) and Andrea P. Zahlis.

Holmberg has spent more than 17 years in transaction advisory, supporting M&A due-diligence engagements first at CSP Associates and now at Arena. By the firm's account he supports "over a dozen due diligence engagements per year" for Fortune 500 companies, mid-market firms, and private-equity groups, with both buy-side and sell-side experience concentrated in defense electronics, military subsystems, aviation services, government IT, and intelligence markets.

Before his advisory career, Holmberg served as a U.S. Army officer — an active-duty infantry platoon leader who deployed to Afghanistan, and later a National Guard intelligence officer mobilized to support U.S. Cyber Command (USCYBERCOM) operations. He holds a BA from Boston University and an MBA from the MIT Sloan School of Management.

• Note: Holmberg surfaces in startup-fundraising aggregator databases (e.g., Foundersuite) tagged as a seed-stage / angel contact, but his verifiable public profile is that of a defense-and-aerospace M&A advisor, not a documented full-time angel investor. Treat the "angel / seed" label as directional rather than a proven mandate.
• Deep domain expertise sits in aerospace, defense, government services, and national-security-adjacent technology — the sectors where any investing or advisory involvement would most plausibly concentrate.
• Strong orientation toward diligence and transaction rigor: his day job is evaluating businesses for acquirers and private-equity sponsors, so he is oriented to fundamentals, defensibility, and market structure rather than momentum.
• No publicly stated personal check size, investment thesis, or standalone angel fund was found in the available sources.
