Legacy modernization and agency operations platform for insurance

Software Development 立川市, 東京都 ~15 employees Founded 1984

SOMPO Systems maintains a mixed enterprise stack (Java, Spring, mainframe z/OS + DB2 alongside cloud AWS/GCP/Azure and modern web React/TypeScript) while facing persistent modernization and productivity challenges. The engineering-heavy org (47 of 55 headcount) with senior-skewed seniority (25 seniors vs. 1 junior) suggests deep domain expertise applied to incremental system upgrades rather than greenfield velocity — consistent with their project mix of legacy migration, agency system maintenance, and on-premises-to-SaaS transitions.
