About Jason Feimster

No ivy league MBA here. Just boots on the ground (if you'll excuse the pun) experience as an entrepreneur and investor in startups. I truly believe the soul of the US Economy is in the growth of small businesses and I'm passionate about finding them, investing in them, and nurturing them to growth. I don't have institutional funds demanding 10x returns in 7 years, so I can focus on you and your company and work together to get the right outcome for both of us. Why should you trust a Marine to invest in your business? Because we know how to work hard, to engage others in our plans, and behave with integrity and honor. We never leave a (wo)man behind and I feel the same way about my portfolio companies.
