Gregory Hold and his brother, Stephen, started the company. Greg was a successful day trader himself before founding the firm. He developed not just a skill for high-speed trading, but also a keen grasp of the unique needs of traders in an ever-changing sector. Greg had a distinct perspective that other C-suite executives didn't grasp because of his experience. He set out to start a business that would provide traders the tools they needed to win quickly and correctly. He chose New York City as the headquarters because he knew it was the best location for accessing all U.S. markets. Even yet, he realized he needed a technical advantage to gain an even larger advantage. Hold Brothers' unique GrayboxTM software platform was created by Greg and his design team, and the rest is history.
