Director of Digital Strategy

Josiah Hritsko is a data-driven YouTube strategist who has helped Theorist earn over 1.9 billion views. He manages ideation, thumbnail development, experimentation, and strategy across the channels.

His evidence-backed approach has helped Theorist maintain consistent growth, earning over 600 million views and 1 million new subscribers since MatPat retired.

Senior Director of Editorial

Melissa Yinger is a seasoned editorial leader and storyteller who works with Theorist’s all-star team of writers, editors, and creative visionaries. She holds a Ph.D. in Literature and brings 10+ years of experience in editorial leadership and content creation that ranges from academic essays to viral shorts and No. 1 iTunes documentaries. She enjoys blending deep research and cultural analysis with YouTube pragmatism (translation: the narrative arc matters, but so does the hook). Favorite part of the job? Finding great creatives and helping them shine — also, not quite believing they pay her to do this.
