Sarah Guo didn’t just grow up around startups—from her youngest years, she was immersed in one.
Her parents ran Casa, a cable and telecom infrastructure startup competing with industry giants like Cisco and Ericsson, and serving customers like Time Warner. The team was relatively small and tight-knit—and it was challenging 10,000-person competitors on the strength of their products. Guo was drawn to startup chaos even then, showing up to the office each day after school. Surrounded by snacks and Diet Cokes, she’d tag along with engineers, soaking up how their jobs really worked and learning to code.
