- Wellthy
Participated · Equity · May 2023
Wellthy provides a tech-enabled care concierge service that matches skilled care coordinators—many are social workers—with families to manage appointments, transportation, equipment and other caregiving logistics. Founded in 2015 and based in New York City, the company moved from direct-to-consumer into employer-sponsored benefits by 2017 and now also works with health plans. From 2019 to 2022 lives covered by Wellthy benefits grew from about 100,000 to 2 million, and revenue increased 17x over that period. Today Wellthy partners with hundreds of companies, including about 30 Fortune 500 employers (six of the top 10) and customers such as Best Buy, Cisco and Hilton; it works with roughly 350 employers, 90% of which are full-time. The company maintains a small private-pay business so employees who leave a sponsoring employer can retain access. To expand its offering, Wellthy recently acquired Lantern, a public benefit corporation that guides families on end-of-life planning. Management says the new capital will be used to build out technology and to support launches with health insurance companies. Wellthy operates a digital care concierge platform that combines dedicated Care Coordinators with a technology platform to manage complex, chronic, and ongoing family care needs. The company partners with employers — including Facebook, Cisco, Accenture, Salesforce, and Voya — to provide no-cost access for employees and their families. Recent product priorities include enhancing its smart recommendations engine, advancing predictive support pathways, expanding self-service tools, and launching an online community for caregivers. Wellthy has recently expanded internationally with launches in Canada and the U.K., and the new capital will fund further international expansion, product development, and continued growth. The company reports 7.5X revenue growth over the past two years, revenue retention greater than 100%, more than 75 enterprise clients representing over 600 businesses, and 700,000+ people receiving no-cost access to its services. Customer impact metrics show improved engagement and productivity (90% more engaged/less stressed, 66% missing fewer meetings, 55% recouped 10+ hours, and 33% avoided leave or resignation due to caregiving support). Wellthy is a NYC-based concierge healthcare service that combines dedicated care coordinators with a technology platform to project-manage healthcare for families. The company schedules appointments, organizes medical records, researches treatment options, manages insurance, and communicates with family members. Its platform stores and organizes information digitally and the business runs on a subscription model. The founding team cites deep personal caregiving experience—CEO Lindsay Jurist-Rosner cared for her mother with MS—and collectively has over 50 years of caregiving experience. Wellthy targets family caregivers (an estimated 66 million in the U.S.) and plans to scale its team, expand its service, and announce partnerships to increase the number of families supported. The company recently closed a seed financing to support those near-term goals.

- Incredible Health
Participated · Series B · Aug 2022
Incredible Health operates a job-matching platform that initially targeted nurses and uses machine learning to screen and match healthcare workers with employers. The company plans to use new funding to optimize hiring workflow with ML-driven screening and matching, expand career support (skills growth, education, mobility and relocation), and add personalized features to its community hub. It is aiming to scale its platform to reach 90% of the U.S. nurse workforce and to expand into other healthcare roles facing critical shortages. The startup reported a more than 500% increase in revenue in 2021 and says more than 10,000 nurses join its marketplace every week. It claims to have reduced average time to hire to 14 days from an industry standard of 82 days, and that around 600 hospitals use its platform for permanent staffing, including more than 60% of top-ranked U.S. hospitals. Incredible Health operates a nurse-focused hiring platform that uses proprietary matching algorithms to pair nurses with hospital vacancies. The platform matches candidates and jobs using roughly 40–50 criteria supplied by both sides, and hospitals only see algorithm-selected candidates while nurses receive inbound employer applications. Since launching its recruitment platform in late 2017 in California, it has signed up 150+ hospitals and “thousands” of nurses. The company claims hires via its platform are three times faster (about 30 days versus up to 90) and deliver 25x hiring efficiency by reducing applicants reviewed from roughly 500 to about 20; it also reports average nurse outcomes of a 17% salary increase and a 15% reduction in commute time. Incredible Health charges hospitals a simple flat fee for permanent hospital roles (not travel/temp) and plans to use new funding to accelerate national U.S. scaling and expand from a hiring product into a career community for healthcare professionals. Financially, the startup raised a $15M Series A and has raised $17M in total to date.
