Stony Lonesome Group is a Venture Capital/Private Equity firm.  From our first 3 Funds - we made early-stage investments.  From our fourth and current Fund - we make investments into later-stage, growth opportunities.

We provide individual investors and small family offices access to unique early stage companies that we originate, lead, and allow them to invest their capital alongside sophisticated sector specific institutional investors.  

Sector Focus

  • National Security & Homeland Defense

  • Cybersecurity & IoT

  • Critical Infrastructure Protection

  • Big Data & Data Analytics

  • Artificial Intelligence & Machine Learning

  • Blockchain

  • Robotics

  • Military Medicine, Healthcare, & Veteran Care

  • Veterans' Affairs

  • Health, Fitness, & Sports

  • Human Performance

  • Investment Advisors, Alternative Investments, & Hedge Funds

We will invest across the capital structure to include equity, debt, and short-term credit financings. Our typical investment ranges from $100,000 to $1mm and we will syndicate larger deals in the $1mm to $10mm range. 

We are hands on investors who leverage our vast network of operating partners and venture partners to help us source, diligence, and monitor our portfolio companies. We tend to take “execution risk” and avoid “technology risk”.

Finally, at the end of the day, we are looking to back strong management teams and provide them with the capital and mentorship to help them reach their potential. A strong investment theme is Veteran Entrepreneurship, backing entrepreneurs and management teams with military service backgrounds.
