About Us

Fifty Stones Capital Group is a direct private lender built for one purpose: getting deals done when others cannot.

We started with a simple observation, too many viable transactions fall apart not because they’re bad deals, but because the capital behind them fails to show up. Lenders retrade, timelines slip, and sponsors are left scrambling. We built Fifty Stones to be the opposite of that.

We provide structured private capital for commercial real estate transactions across the United States, with a focus on speed, discipline, and certainty of execution. From time-sensitive acquisitions to complex transitional assets, we step in where traditional lenders hesitate and bring clarity to situations that often feel anything but.

Our name reflects our reach. Each “stone” represents one of the 50 states we serve, markets where we don’t just claim to lend, but actually execute. Whether it’s a straightforward bridge loan or a deal with more moving parts than a watch, we approach every transaction with the same objective: structure it correctly and close it.

At Fifty Stones, we don’t chase volume and we don’t rely on guesswork. We underwrite with intent, move with purpose, and focus on delivering capital that performs when it matters most.

Because in this business, talk is common. Execution is not.

Mark Shea didn’t enter real estate and finance by accident, he came up through it, one deal at a time. Early in his career, Mark found himself on both sides of the table, working through acquisitions, navigating financing structures, and seeing firsthand how often deals fell apart not because they didn’t make sense, but because the capital behind them wasn’t built to perform. It didn’t take long to realize that in this business, knowing real estate is only half the equation. Understanding capital, how it moves, where it breaks, and how to structure around risk, is what actually gets deals done.

Over the years, Mark developed a reputation for stepping into situations others avoided. Complex transactions, tight timelines, unconventional assets, cases where most would hesitate, he leaned in. It was that approach, measured, analytical, but quietly confident, that attracted the initial group of investors behind what would become Fifty Stones Capital Group. ​
