Thatch has raised a $108 million Series C at a $1 billion valuation, the company announced, pushing its bet that employers should hand workers a health budget rather than a one-size-fits-all group plan into unicorn territory.
The round was led by The General Partnership, with participation from Index Ventures, Scale Venture Partners, General Catalyst, Andreessen Horowitz, Avid Ventures, Quiet Capital, SemperVirens and QuantumLight. Notably, the cap table now includes strategic checks from Eli Lilly, ADP Ventures and Paychex — pharma and payroll incumbents with a direct stake in how employer health benefits get administered.
The model
Thatch is built on ICHRA — the individual coverage health reimbursement arrangement. Instead of picking a group plan, an employer gives each employee a defined budget; the employee buys their own plan and can spend the remainder through the Thatch Marketplace on services like mental-health support and biomarker testing. Founded roughly five years ago and led by co-founder and CEO Chris Ellis, Thatch says it now serves more than 5,000 employers, with annual recurring revenue up nearly 7x year over year.
What the money buys
Thatch says the capital will go toward better member-navigation tools, deeper carrier partnerships, more payroll integrations and a smoother user experience — the unglamorous plumbing that determines whether "give people a budget" actually beats the group plan on employee experience.

ICHRA — letting employers fund individual coverage instead of buying a group plan — has been the most-hyped structural shift in employer health benefits, and a $1B valuation with strategic money from Eli Lilly, ADP and Paychex is the clearest signal yet that the payroll and pharma establishment is betting the 'budget, not a plan' model is real. For HR and benefits buyers, it raises the pressure on traditional group-plan brokers and makes ICHRA administration a category worth evaluating, not just watching.
