The SourceFed channel found early success in attracting a sizable subscriber base. DeFranco later created a spinoff channel, SourceFedNerd (stylized as SourceFedNERD), which was announced on May 16, 2013. A teaser trailer was released, promising the debut of the channel on May 20. The New Movie Thing Show, The SourceFed Movie Club, and #TableTalk were moved from the original SourceFed channel to the Nerd channel. The spinoff channel hosted a live version of the #TableTalk series during the YouTube Comedy Week in 2013. The online stream was received well, being successful in terms of both raw viewership, as well as viewer retention.
While discussing the dissolution of SourceFed Studios, DeFranco retrospectively detailed that after selling his DeFranco Creative umbrella to Revision3, he began to have less involvement in SourceFed, before having no involvement at all. DeFranco expressed, "for you [long time viewers of SourceFed] who know what the original content was, and what it is now, you know that it's like, it's pretty much a completely different channel—both in content and the people running it." Previously, in June 2016, DeFranco made his earliest public clarification that he has "no hands on the creative decisions [made] on [SourceFed]."
On September 19, 2013, the SourceFedNerd channel reached 500,000 subscribers.
