Waterlily

Waterlily is an AI-native, end-to-end long-term care (LTC) planning platform for financial advisors, insurance professionals, and the families they serve. Trained on more than 500 million data points, its models predict an individual's personalized likelihood of needing long-term care, project the cost and duration of that care, and estimate the caregiving hours each family member is likely to contribute. A roughly three-minute intake produces a personalized care timeline and plan with localized cost estimates, and its Quote-and-Apply engine computes mathematically optimal LTC insurance policy configurations across hundreds of thousands of options. Founded by Lily Vittayarukskul and backed by Insight Partners. Waterlily is surfaced in the API Evangelist network as a portfolio-lead company; it exposes no public developer API today (integrations are one-click CRM imports for Salesforce, Wealthbox, and Redtail).

Waterlily is profiled on the APIs.io network. Tagged areas include Company, Healthcare, Long-Term Care, Insurance, and Financial Planning.

Waterlily’s developer surface includes engineering blog, pricing, signup flow, support, and 6 more developer resources.
