Inspect the highlighted sourceThe challenge
SIGNAL IDUNA, a major German health insurer, faced rising inquiry volumes, a shortage of skilled talent, and the loss of institutional knowledge as roughly 30% of its workforce nears retirement, while needing to navigate strict regulations like the EU AI Act and the Digital Operational Resilience Act without slowing innovation.
The solution
SIGNAL IDUNA partnered with Google Cloud to roll out the Gemini Enterprise app (branded internally as Co SI) company-wide to 10,000+ employees and sales partners within six months, giving employees a single hub to use Google-made agents, specialized SIGNAL IDUNA agents, and to build their own no-code custom agents. Over 100 internal AI champions used Agent Builder to create agents such as an intelligent message-routing agent and a language agent for insurance terminology, while the Co SI Health knowledge agent -- built with Google Cloud, BCG, and Deloitte -- uses Document AI to extract and structure over a century of policy documents across 600+ tariffs and Gemini models to reason across that knowledge base.
Reported business value
80% of the workforce became weekly active users of Gemini Enterprise with a +45 Net Promoter Score in the first five months; AI champions built 200+ custom agents in two weeks; the intelligent routing agent cut the customer-message routing error rate by 40%; weekly usage of the Co SI Health knowledge agent rose 400%; and employees can now find answers in thousands of complex policy documents in about 20 seconds.
