  • Marigold Health

    Led · Series A · Jun 2024

    Marigold Health offers a proprietary peer support program that pairs one-on-one coaching from certified peer specialists with 24/7 text-based support groups in an app integrated with NLP that flags health needs in chats. The company has demonstrated real-world outcomes: a 2020–22 pilot with a major managed Medicaid organization in Delaware made Marigold the state’s largest provider of peer recovery supports, and an outcomes analysis of 1,000 app signups found 98% reported improvement in at least one dimension of Recovery Capital. Today the program covers about 25,000 members across Delaware, Rhode Island, and Massachusetts. Marigold is prioritizing partnerships with Medicaid and duals health plans and is pursuing a value-based reimbursement model to tie improved member outcomes to lower total healthcare costs. The company plans to grow its peer workforce, continue developing its NLP, expand to at least four additional states by the end of next year, and pursue a longer-term vision of a nationally distributed peer delivery model that can support chronic conditions beyond SUD. Marigold Health runs a virtual program that uses trained peers—individuals in recovery—to support others via 24/7 text-based group chats. The company has patented natural language processing technology to help peers moderate its online community and has validated the approach in federally funded studies. A NIDA-funded Phase I study of 50 patients with opioid use disorder reported 64% daily use of the Marigold app across a two-month period. Since 2016 Marigold has engaged thousands of patients and reports that over 75% of current members are on public health insurance. Its service has been adopted by health plans and providers—AmeriHealth Caritas DE offered Marigold to more than 10,000 members with SUD, and Wood River Health Services will offer it in Rhode Island. Marigold plans to build state-level peer workforces and pursue Medicaid plan partnerships to expand access in communities affected by the opioid epidemic.
