Team

The people behind the work.

Profile · 01 · Co-Founder & CEO

Naomi Rauscher

Naomi is a co-founder and the CEO of Hierarchy, and the person who turns plans into delivery. She leads the company and owns the operational backbone of client work: campaign execution, automation workflows and the communication that keeps projects moving. She makes sure what gets designed actually ships. She pairs marketing instinct with a writer's ear for language, so the campaigns and content that go out sound like people wrote them, not templates. Where Tenzin and Martin build the systems, Naomi is the reason they run day to day.
