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. 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".
