Cirrus Logic

The chipmaker does the bulk of its business — at least 80% -- with Apple and the two firms' fates are tightly intertwined. Cirrus Logic's audio chips are found in everything from the iPad mini to the iPhone. when the semiconductor firm posted disappointing revenue forecast this Spring, Apple's stock also took a tumble. The Austin-based firm still posted $136.6 millio in revenue, up from $88 million last year. What's more, analysts are predicting that its growth will slow down. The question is whether Cirrus will manage to maintain its biggest account going forward.

Opentable

Opentable

Opentable — founded during the first dotcom boom — still leads the restaurant reservation sector. It was feared that the San Francisco-based company would lose ground to international competitors expanding in the U.S. but it still has more restaurants using its booking software and more diners using its site. Opentable's acquisition of food-social site Foodspotting and mobile technology firm Just Chalo has also put it on track to dominate the mobile-booking market, while other expansion efforts have focused on gaining market share abroad, notably in the U.K.

3D Systems

3D Systems

3D printing promises to transform manufacturing. Chuck Hull — who founded 3D Systems — created the first 3D printer in 1983. Now the technology is finally becoming more wide spread (and hyped). Data can be inputted into printers that lay down thin layers of material, plastic or metal for instance, to create everything from gun parts to artificial limbs and jewelry. The company's products range from the Cube, a personal 3D printer sold at Staples for $1,300 to production printers used by the likes of General Motors to prototype new parts. The company brought in $378 million in revenue over the past year. Not surprisingly, its annual growth rate has been a scorching 119%.
