5 Tiny Companies Making Millions

NEW YORK (MainStreet) -- What do organic baby food, the relief of back ailments, nutritional water, IP-phone services and a golf simulator all have in common?

Companies with less than 50 employees figured out how to turn each of these niches into multi-million dollar revenue streams.

No easy task, and the secret of these successful entrepreneurs is to find where the opportunity is and make sure your product is one that consumers (or commercial customers) can't live without. Though once the products gave these companies their start, they didn't rest on their laurels. Staying focused on their industries and constantly considering new products or markets keeps these companies in growth mode.

Shazi Visram launched Happy Family on Mother's Day in 2006 after being unable to find suitable home style healthy, organic baby food options.

She started the company with the intentions of making the food for her friends' babies and her own family, but the concept took off. Six years later, Happy Family products are available in more than 17,000 stores nationwide and on Amazon(AMZN) and Diapers.com.

Last year, revenue totaled $34.7 million, up from $156,000 in 2006.

What's more impressive is that this is all done with a staff of just 32 full-time workers.

Happy Family's beginnings were very grassroots. After Visram's company started selling at a New York City grocery chain, it hired part-time workers (called "Happy Mamas") to spread the word about their products by handing out coupons to moms in parks and playgrounds. The company now has more than 50 Happy Mamas across the U.S.
