Company News
Anzen is the System of Execution for insurance — AI that does the work inside every policy transaction across the systems you already run.
Thatch has raised $108 million at a $1 billion valuation to expand its health benefits platform. The San Francisco-based company now serves more than 5,000 employers and has seen revenue increase nearly sevenfold in the past year. The financing was led by The General Partnership, Index Ventures, General Catalyst and Andreessen Horowitz, with participation from ADP Ventures, Paychex and Eli Lilly and Company, among others. Thatch's platform allows employers to provide defined healthcare budgets to employees, who can then choose individual health insurance coverage based on their personal needs. This differs from traditional group health plans where employers select coverage for their entire workforce. The company has integrated with major health insurance carriers and payroll providers including ADP, Paychex, Gusto and QuickBooks. Thatch aims to make healthcare purchasing decisions more consumer-driven, with plans to incorporate AI agents to help individuals navigate care options.
