Unified Payments

Oleg Firer, Founder and CEO
North Miami Beach, Fla.

No. 1
2011 Revenue: $59.5 million
Three-Year Growth: 23,646%

Oleg Firer started his payment-processing company in 2003, but it wasn’t until 2008 that it began its significant growth. It was then that Unified Payments acquired eight equity-distressed competitors struggling through the recession. Firer shut most of those companies down and absorbed their customers into Unified Payments. His holding company now services more than 100,000 merchants in the United States and handles approximately $10 billion in transactions annually. Firer believes the growth will continue because consumers are becoming increasingly averse to using cash. "We make money no matter what the economy is doing," he says.
