Company

Built by two founders who wanted influence done right.

Founded in 2018 by Cathy Pill and Sarah Levin Weinberg, Stellar was created to solve a simple problem: influencer marketing was growing fast, but the tools were fragmented, manual and hard to scale. Coming from fashion on one side and digital and tech on the other, they built Stellar to bring more structure and intelligence to the industry. Today, Stellar develops AI-powered technology for brands and agencies worldwide, while its founders remain actively involved in the Women in Tech ecosystem.
