About Flintlock

Meet the Leadership...

We are an entrepreneur first firm, created by founders who share a deep understanding of what right looks like. Having sat at both ends of the deal table, we have a first-hand understanding of the difference a great VC partner can make. We also understand the incredible challenge of creating, growing, and exiting the entrepreneurial journey.

We bet heavily on investing in the right people, even if the idea itself needs development. The idea will evolve and improve, especially in the care of a great entrepreneur. At our heart, we are an entrepreneur’s investment management company because we know we cannot force an investment’s success. We only succeed when our entrepreneurs succeed.

Seda has made it her mission to help veterans translate their military skills – leadership, teamwork, discipline, and flexibility – into launching and scaling successful businesses. She has written several opinion editorials on this subject in Military Times, Fox Business & Yahoo! Finance.
