Insurance Chattanooga, TN 10,001+ employees Founded 1848 Public Company

Unum is a large-cap insurance company rooted in disability and life coverage, now expanding into voluntary benefits, dental, vision, and behavioral health. The tech stack is heavily legacy-oriented—COBOL, z/OS, mainframe DB2, VSAM—paired with modern cloud (AWS, Databricks) and BI (Power BI), suggesting a multi-decade migration from monolithic insurance systems toward cloud analytics. Hiring patterns show sales-led growth (24 active sales roles) combined with operational and claims-processing friction: pain points cite inconsistent sales processes, low adoption of lead-management systems, and claims-processing inefficiency, indicating internal tooling and process maturity gaps.
