IceFrog

IceFrog is the lead developer for both Dota 2 and the original Defense of the Ancients. To date, he has remained pseudonymous, and other than revealing that he was 25 years old in early 2009, characteristics such as his physical description and real name are unknown.

IceFrog officially began his involvement with Defense of the Ancients in 2005, when he was recruited by Guinsoo--the mod's lead developer at the time--to assist with programming. Later that year, Guinsoo left the project and passed the lead developer position to Neichus, who continued to develop with IceFrog. Neichus' departure a short time later left IceFrog as the sole designer for the map. Since then, IceFrog has ushered in an era of competitive play by consistently balancing and renovating the game.
