The Arena Collective

A network of builders, strategists, and operators united by one mission — helping entrepreneurs grow by design, not by default.

The Arena Gauntlet Team

Mark Fleming

Arena Founder

After bootstrapping his company, Signature Closers, to more than $65 million in annual revenue and successfully exiting to a Fortune 800 buyer, Mark distilled the lessons of that journey into a repeatable framework for entrepreneurs. His background spans sales, operations, finance, and strategy—and his philosophy anchors Arena’s purpose: to help business owners build companies that thrive without them, and lives that thrive beyond them.
