Her aunt’s care nearly broke the family. Lily Vittayarukskul built Waterlily so other first-gen kids see the bill early.

Lily Vittayarukskul was supposed to keep building rockets. At 11 she won a NASA water-rocket competition and visited Kennedy Space Center. As a teenager she interned on the aerospace path and started college at 14. Then her aunt, who had lived under the same roof and helped raise her, was diagnosed with terminal colon cancer. The diagnosis was devastating. What redirected her career was the bill that followed, and the quiet way it emptied a Cambodian immigrant family’s savings and strained every relationship in the house.

Vittayarukskul is 30 now, co-founder and CEO of Waterlily, a San Francisco company that uses AI to estimate when someone may need long-term care, what it could cost, and how a household might pay. In late July she told that origin story in a Business Insider as-told-to essay. The useful file for first-gen readers is not another founder myth. It is the coverage gap her family hit, and how often diaspora households still assume a hospital plan or Medicare will catch what is really years of bathing, meals, and night shifts at home.

Her aunt spoke little English, so Vittayarukskul’s mother translated at appointments. After chemotherapy, the aunt became frail. The family, originally from Cambodia, spent roughly two and a half years covering daily long-term care needs that health insurance did not treat as medical care. “It wiped us out financially,” she later told TechCrunch. In the Insider essay she remembered the quiet more than any single meeting: everyone exhausted, moving from factory work to caregiving without language for what was happening. She went to her parents’ factory after school and often stayed until 10 or 11 p.m. Only later did the full cost show: strained relationships, blame, isolation, and almost nothing left after her aunt died.

That surprise is written into federal coverage rules, even if families discover it in a living room. Medicare, the federal health program for people 65 and older and for some younger people with disabilities, does not pay for custodial long-term care. Custodial care is help with everyday tasks such as bathing, dressing, eating, and getting in and out of bed. Medicare can cover short, skilled nursing or rehab stays after a qualifying hospital stay, usually measured in days or weeks, not years at home. Most ordinary health insurance follows the same line. Medicaid, the joint federal-state program for people with limited income and resources, is the main public payer when nursing-home stays stretch long; KFF data put Medicaid as the primary payer for roughly six in ten nursing-facility residents. Qualifying often means spending down first. None of that is intuitive when a relative still has “good insurance” on paper.

The price of the private market makes the gap feel personal. CareScout’s 2025 Cost of Care Survey, which Genworth’s CareScout unit publishes from tens of thousands of provider rates, put the U.S. median for assisted living near $6,200 a month, or about $74,400 a year. A private nursing-home room ran about $355 a day, or roughly $129,575 a year. Semi-private sat near $114,975. Those are national medians, not your ZIP code, and home care can look cheaper until someone in the family quits a shift or a sibling stops sending remittances. AARP’s 2026 update of Valuing the Invaluable estimated that about 59 million family caregivers of adults provided 49.5 billion hours of unpaid care in 2024, worth about $1.01 trillion at an average of $20.41 an hour. The unpaid workforce is the real long-term care system for many households. Immigrant families with limited English elders often carry an extra translation load on top of the hours.

Vittayarukskul’s response was to leave the aerospace track for genetics and data science at UC Berkeley, lead product and engineering at early healthcare startups, and found Waterlily in December 2021. Evan Ehrenberg, who had founded Clara Health and sold it in 2022, joined as co-founder and chief operating officer after an early angel stretch. The company launched publicly around March 2024. It markets personalized projections from more than 500 million data points and a free consumer tool alongside software for advisors and agents. In January 2025 it closed a $7 million seed round led by John Kim of Brewer Lane Ventures, with strategic checks from Genworth, Nationwide, and Edward Jones, on top of an earlier $2.2 million pre-seed. Company and press math put total raised near $9.2 million. Forbes named Vittayarukskul to its 2026 30 Under 30 list in Social Impact. That is the résumé. It is not a shopping list.

Treat the company news as proof that the parent-care problem is large enough for insurers and venture funds to chase, not as a reason to buy a policy from a headline. Long-term care insurance, hybrid life policies with care riders, annuities, and self-funding all have trade-offs that depend on age, health, assets, and whether parents live in the United States or abroad. An AI estimate is still a model. Your job is to put real local rates, travel costs, and sibling capacity on one page before anyone promises to “just take care of it.”

For diaspora households, the practical sequence looks familiar. Ask what Medicare or a parent’s employer plan actually covers for help at home, and write down the answer in plain language. Price one year of care in the city where your parent actually lives, not the national median alone. Decide what you can put on a monthly family-support line without raiding rent or retirement. Then hold a sibling check-in that names hours and dollars before a crisis forces the assignment onto the person who translates best. The relationship damage Vittayarukskul described is not a side effect. It is what happens when money and care stay unspoken until nobody has anything left.

If her aunt were alive, Vittayarukskul has said, the questions would be whether the work helps people and whether the business can last. Generational’s version for readers is narrower. See the coverage gap before the hospital discharge. Cap what you can fund. Share the load in writing. The rocket career can wait; the care calendar usually will not.
