About

Hey 👋 I’m a Clay customer turned team member because I love the product so much! Before joining Clay I led client services for Volley, a lead generation agency and signed the first 15 customers for our AI email personalization tool. Before Volley, I co-founded a workplace culture building software, closing our first 40 customers and getting us to $1M ARR.
