Built by a Seller, for Sellers: The Story Behind Subhoo with Mark Flournoy

In this episode of The Peel, David Blackburn sits down with Mark Flournoy, a Marine Corps veteran and the founder of Subhoo, which is redefining how federal sales and BD teams uncover teaming relationships across the government contracting landscape. Drawing from two decades of experience, both as a government insider and a commercial seller with companies like Amazon, Red Hat, and F5, Mark created Subhoo to solve a very personal pain point: the frustrating lack of clear, actionable insight into prime-subcontractor dynamics.

Mark shares how he’s personally building and refining the tool based on real-world feedback, what’s next on his roadmap (think: better search, burn rate insights, and smarter filters), and why honest critique is the key to creating something genuinely useful in the GovCon space.

Whether you’re a federal seller trying to break into a new agency, a BD leader managing up and across, or just someone tired of paying big bucks for complex tools you rarely use, this conversation might just change how you approach the market.
