Go-to-market is relationship-led via licensed agents at branch offices, augmented by digital channels including website quote-request forms for each business unit, the Dimond Vault client portal (delivered through a GloveBox-powered mobile app) for self-service policy management, and the Dimond Wrap-Up OCIP contractor portal (built on VUE Wrap-Up) for construction wrap-up projects.
