Chelsa Materi

Chief Growth Officer

In April 2025, Chelsa Materi was named Chief Growth Officer at Sandbox Mutual Insurance—continuing a journey that started in 2007, when she joined the company as an Underwriter. From day one, Chelsa has been a champion of smart, flexible insurance solutions that are easy to understand and built around the real needs of policyholders.

Prior to stepping into her CGO role, Chelsa served as AVP, Underwriting, beginning in January 2021, where she led product development, streamlined underwriting processes, and helped make policyholder experiences faster, simpler, and more transparent. Now, as Chief Growth Officer, she’s focused on driving strategic expansion, enhancing value for policyholders, and creating new opportunities to connect with brokers in meaningful ways.
