Territory plans should start with Foster City, CA and then map regional hubs by function. Security, infrastructure and data-platform sellers often need US executive sponsorship plus technical champions in engineering or R&D centers.
Field events, ABM and partner coverage should align to the office where the buying committee actually works, not just the legal headquarters.
