For his latest experiment, YouTuber Mark Rober is bringing his skyrocketing popularity onto the market’s leading streamer.

Netflix has ordered a kid-friendly competition series that Rober, an inventor and former NASA engineer, will host and executive produce through his CrunchLabs banner. Late-night TV host Jimmy Kimmel is also lined up as an EP through his company Kimmelot, which has previously partnered with Rober to make Discovery Channel titles like This is Mark Rober and Revengineers.

The new Netflix series will roll out in 2026, and there’s not much info yet on what shape its competition format will take. But based on this social media teaser (and the nature of Rober’s well-known viral content), it’s safe to expect a healthy dose of STEM-based hijinks. Rober is very popular with kids, thanks to his brand of videos that fold educational lessons into zany challenges—like creating the world’s largest Jello pool or battling robots with rival creators Dude Perfect.

Netflix has also acquired some existing content from Rober’s YouTube channel (70.5 million subscribers) to launch later this year.

The streamer has been successful in leveraging the popularity of YouTube creators lately, most notably Ms. Rachel, who has 16.3 million YouTube subscribers. The preschool star’s licensed videos generated 53 million views on Netflix in the first half of 2025, making her debut one of the most-watched individual seasons on the platform this year across all genres.
