In this episode of TheMilVet Podcast, host Beau Higgins sits down with Randy Mullen, Founder & CEO of Sightline Ventures and a former U.S. Air Force Officer, to explore his journey from military service to building a mission-driven company in the defense tech space.

Randy shares how his upbringing near Edwards Air Force Base first sparked his interest in the military, eventually leading him into Air Force contracting and acquisitions. With experience spanning global deployments, the National Reconnaissance Office, and the Education with Industry program at Ball Aerospace, he developed a deep understanding of how the Department of Defense operates and how innovation reaches the warfighter.

Throughout the conversation, Randy offers a candid look at one of the hardest decisions of his life: stepping away from a promising military career and command opportunity to prioritize his family. He opens up about the emotional weight of that transition, the uncertainty that followed, and how a series of unexpected pivots ultimately led him to entrepreneurship.

Listeners will gain insight into:

• Choosing family over career and navigating the tension that comes with it
• Embracing uncertainty and adapting when plans fall apart
• Translating military experience into entrepreneurship and business development
• Building a company with purpose while continuing to serve beyond the uniform
• Taking calculated risks and betting on yourself during transition
• Reinventing yourself to stay challenged, relevant, and growing
• Investing in mentorship, personal development, and long-term vision

Randy also shares how Sightline Ventures is helping early-stage defense tech companies bridge the gap between innovation and implementation, ensuring critical technologies get into the hands of those who need them most. His story is a powerful reminder that while transition may be messy and unpredictable, it can also open doors to impact, growth, and renewed purpose.

Whether you’re navigating your own transition, exploring entrepreneurship, or looking to lead with greater intention, this episode delivers practical insight and real-world perspective to help you move forward with confidence.

In this episode of TheMilVet Podcast, host Beau Higgins sits down with Mike Gaffney, Naval Academy graduate, former nuclear-trained submarine officer, and now CEO of Cellphire Therapeutics, Inc., to unpack a career that spans undersea operations, top-tier consulting, private equity, and biotech leadership.

Mike shares how growing up around his father’s Naval Academy classmates and mentors, including a future vice admiral, shaped his decision to attend the Academy, not for prestige, but for values, character, and leadership. An unlikely nuclear submariner who majored in English and later earned a graduate degree in politics, he explains how the process of elimination, the end of the Cold War, and a few hard realities (like getting seasick and wearing glasses) pushed him beneath the surface and into the Navy’s nuclear community.

Mike then walks through his pivot from consulting into the investment world with Allied Capital, where he ultimately became the firm’s de facto healthcare lead. He breaks down how the private equity landscape has transformed since the late ’90s, from a smaller, less crowded field to today’s hyper-competitive market where deal flow, specialization, and relationships are everything and why that shift pushed him toward building companies rather than just backing them.

Throughout the conversation, Mike offers practical insight on:

• Leveraging your network the right way; focusing on adding value, reciprocity, and long-term relationships rather than transactional asks
• Translating military leadership into commercial settings by obsessing over team quality, clarity of purpose, and execution discipline
• Surviving “getting punched in the face” in business through resilience, problem solving, and resourcefulness forged in uniform
• Understanding how modern private equity and growth capital really work; why deal flow, specialization, and operating value creation matter more than ever
• Stepping into a new leadership role with humility, curiosity, and a deliberate approach to listening before changing things
• Shaping culture intentionally so strategy doesn’t just live on a slide, but shows up in daily behaviors and decisions

For veterans interested in private equity, venture capital, or executive roles in high-growth companies, Mike offers grounded advice: this is a brutally competitive space where many people want the same jobs, but trusted introductions, demonstrated grit, and a reputation for solving hard problems can differentiate you. He emphasizes that trust and likeability aren’t built in one conversation or a single coffee, they compound over time through consistent behavior, follow-through, and showing up for others.

In this episode of TheMilVet Podcast, host Beau Higgins sits down with Matthew R. Brooks, Founder and Principal of Second Echelon Capital, Colonel, US Air Force (Retired) and U.S. Air Force Academy graduate to explore his journey from the cockpit to entrepreneurship, and now to investing in fellow veterans.

A graduate of the United States Air Force Academy, Matt shares how a single touchdown catch against Notre Dame became a lifelong lesson in teamwork, humility, and mission-first leadership. He reflects on his Air Force career, commanding the 5th Bomb Wing, and the values that shaped him; integrity, service, and excellence.

But Matt’s story doesn’t stop at retirement.

After leaving active duty, he stepped into the world of entrepreneurship, acquiring and scaling his family’s hotel supply company before successfully exiting. Now, as founder of Second Echelon Capital, he invests in veteran-owned small businesses, helping other service members navigate the path of entrepreneurship through acquisition (ETA).

Throughout the conversation, Matt dives into:

• The realities of military transition; what he expected vs. what surprised him
• Entrepreneurship through acquisition (ETA) and why buying a business can be a powerful path for veterans
• The sleepless nights, financial pressure, and hands-on leadership required to run a small business
• Why community matters, and how organizations like Entrepreneurs' Organization help founders avoid going it alone
• Translating military leadership into building systems, processes, and high-performing teams
• Aligning your commercial pursuits with your personal passions
• The importance of mentorship, financial readiness, and learning when to say “no”

Matt also shares practical resources including books, podcasts, and conferences for veterans interested in business ownership, along with candid advice about preparing your family and finances before taking the entrepreneurial leap.

Whether you're a transitioning service member, a veteran considering buying a business, or a leader looking to invest with purpose, this episode offers a real-world look at what it takes to move from leading airmen to leading companies, and from operator to investor.
