If you were to put the words "startups" and "California" in a list and asked for a city, most people would say San Francisco, or its nickname Silicon Valley. But you cannot brush off Los Angeles--the City of Angels when it comes to business.

Although you won't find famed-Silicon Beach haunts Roscoe's or Philippe's on the list, you will find companies that have been working hard and growing their bottom lines.

Below are the top 10 fastest-growing, private companies in LA:

10. I.T. Source

Founded in 2002 by CEO Andy Kim, who was 19 years old at the time, I.T. Source started as a computer building and installation company. A few years after launch, the company's revenue started to decline but Kim's mother took charge and led the company to pivot its offerings and avoid failure. Instead of computers, the company sold credit card processing services to small businesses and brokering wholesale cellular minutes. Today, the company mainly provides IT infrastructure support provider that provides outsourced call center services, cloud-based hosting services and custom Web programming and graphic design services. It still operates a credit card processing unit called Unlimited Merchant Services.

With a three-year growth rate of 1,075 percent, the company, which reeled in $102.8 million in 2013, came in at number 444 on the Inc. 5000

9. Dope

With its roots in the Midwest, Dope is a luxury streetwear company that makes a line of T-shirts, hats, sweats, jerseys, tanks, and accessories worn by the likes of hip-hop artists including Jay-Z, P. Diddy, and Wiz Khalifa.

Founder Matte Fields started the brand in 2007 while at Indiana University. He got his break when Lupe Fiasco bought one of Dope's t-shirts in a store in Michigan. The company's rep rose when Atlanta rapper 2 Chainz was arrested in New York City's LaGuardia Airport while trying to board a plane with one of Dope's four-finger rings in his bag. (It closely resembled brass knuckles.) The purchase hit the Internet, they opened a boutique in LA, and the rest is history.

Ranking at number 356 on the Inc. 5000, Dope's 2013 revenue ($5.4 million) grew 1,331 percent in the three-years ending in 2013.
