Frequently asked questions
What sectors does Stony Lonesome Group target?
The firm concentrates on dual-use technologies across AI, cybersecurity, healthcare, quantum computing, unmanned aerial vehicles, and deep tech. Its investment thesis favors products that can scale in both government and commercial markets simultaneously.
Who runs investment decisions at Stony Lonesome Group?
Founder and Managing Partner Sean Drake leads investment decisions. He is supported by Partners Brooks Bash, Don Noble, and General Partner Patrick Murphy, who chairs the Military Advisory Board and brings direct defense-sector sourcing capabilities.
Is Stony Lonesome Group a single family office or a venture firm?
Stony Lonesome Group operates as a venture capital firm, not a family office. It accepts limited-partner capital and has deployed $125M across more than 70 companies since 2011 (per the firm).
How does Stony Lonesome Group source proprietary deal flow?
The firm builds an 'SLG Deal Team' for each investment, staffed by former Special Forces operators and defense-acquisition veterans who originate and diligence opportunities within the national-security ecosystem. Over 80% of portfolio companies are led by military veterans, reflecting deep sourcing ties to the veteran-entrepreneur community.
What investment stages does Stony Lonesome Group typically target?
SLG invests from seed through late-stage growth rounds. Its public materials emphasize early-stage dual-use companies, though the portfolio spans more than seventy companies across the startup lifecycle.
Does Stony Lonesome Group participate in fund commitments or only direct deals?
The firm structures investments as direct equity and co-investments. There is no public indication of fund-of-funds commitments or limited-partner positions in peer venture funds.
Does Stony Lonesome Group maintain a specific veteran mandate?
Veteran-led entrepreneurship is central. SLG reports that over 80% of its portfolio companies are founded or managed by military veterans, and its operating model deliberately integrates former military personnel into diligence and portfolio management. It has also been recognized for creating more than 1,000 jobs for veterans and their spouses.
