"Zepto" is a math term for the very tiny number 10-21, but for fraternal twins Semyon and Efim Voinov, it would become the name of their game company.

"We were a very, very small lab – just the two of us – so the name 'ZeptoLab' made sense," Efim told us.

"It also sounded cool," said Semyon.

ZeptoLab first made waves in 2010 with the release of its game Parachute Ninja, which was met in Apple's App Store with modest success. In an effort to continue riding that success, the brothers got to work on the game that would become a resounding hit, Cut The Rope.
