  • Chief Of Staff at Series

    Effortlessly automate payments, global payroll & HR, treasury management, contracts, and more— all within a modular & modern ERP alternative, the Series EOS. 1. Joined as Employee #1. Learned how to, and not to, scale from 0-1. 2. Built the playbook and processes as our 1st CS, BD, and Operations rep. I made lots of mistakes. 3. Led Sales and Strategy over last two years. I made even more mistakes, but learned a lot.
