Insurance Manchester, New Hampshire 201–500 employees Founded 1999 Privately Held

RiverStone manages legacy insurance claims and reinsurance recovery for mid-market and enterprise insurers navigating run-off portfolios. The tech stack is heavily Azure-native (App Service, Functions, Logic Apps, DevOps, Monitor) with .NET/C# as the primary application layer, suggesting a mature internal platform designed for claims processing at scale. Current hiring focuses on legal and finance roles—nine and eight open positions respectively—while engineering remains thin (two roles), indicating RiverStone is operationally scaled and now optimizing for regulatory compliance and financial accuracy rather than product expansion.
