Complexly
Complexly, Inc. is an online educational audio and video production studio, headquartered in Missoula, Montana. In February 2026, Complexly founders John and Hank Green donated their equity to restructure the company as a 501(c)(3) nonprofit, focusing on the production of free, accessible, and fact-based educational videos. Complexly produces educational videos distributed through their YouTube channels including Crash Course, SciShow, and more.
Originally named EcoGeek LLC, it was founded by Hank Green to support his blog on environmental and science issues and was renamed in 2016. Also associated with the Green brothers, but separate from Complexly's operations, are DFTBA Records, the Project for Awesome, VidCon (acquired by Viacom), and Subbable (acquired by Patreon). The company's strengths in educational content has led to production funding from Google, PBS, and the Poetry Foundation, among other corporations and charitable foundations.
Julie Walsh Smith became acting CEO of the company in September 2023, and the Green brothers are now listed as founders on the company's website; Smith was later named as permanent CEO.
Early 2024 saw Complexly venture into their first esports sponsorship, signing Blue Scuti, who had just gone viral as "the boy who beat Tetris".

Crash Course is an educational YouTube channel providing many courses of study, often based around the AP curriculum of a given subject. The level of study matches that of high school or early college, but the content is available for all ages. Many courses are co-produced with PBS Digital Studios. The channel launched in 2012, with two subjects, World History and Biology, being taught by John Green and Hank Green, respectively.

SciShow is a series of science-related videos, hosted primarily by Hank Green and Michael Aranda. Video topics include breaking scientific news, in-depth analyses of scientific concepts and science history, and science fact compilations. A spin-off channel, SciShow Space, launched in April 2014 to specialize in space exploration, astronomy, and cosmology. A second spin-off, SciShow Kids, launched in March 2015 to specialize in delivering science topics to children. Kids went on hiatus in late 2018, returning in April 2020. A third spinoff channel was announced in February 2017, SciShow Psych, which debuted in March 2017, specializing in psychology and neuroscience. A podcast, SciShow Tangents, was launched in November 2018; it features entertaining exchanges of scientific facts among many of the shows' staffers, and is directed at a mature audience.
