Mark Rober style guide
Mark Rober is a former NASA engineer and YouTube creator with over 76 million subscribers. In 2025, his company CrunchLabs signed a major publishing deal with Scholastic. For the first time, the brand required a defined content system to translate Mark’s video-native voice into print. I created the first draft of that style guide, auditing video transcripts and brand guidelines to establish scalable voice, tone, and language across a new product surface.
