Flo Health founder-backed Trellis Health emerges from stealth with $1.8m pre-seed funding
The startup begins as a pregnancy and postpartum support app integrating medical data
A digital health startup backed by the founders of leading women’s health platform Flo Health and a roster of high-profile investors has launched out of stealth with $1.8m in pre-seed funding, promising to tackle the often-overlooked complexities of women’s healthcare - starting with pregnancy and postpartum.
Trellis Health, founded by Estelle Giraud, a former commercial leader at genomics giant Illumina, is positioning itself as a ‘modern-day family doctor’ by offering personalised, AI-powered care that integrates years of medical history into a single, comprehensible timeline. The platform is designed to address what Giraud describes as “glaring gaps” in the healthcare system, particularly for women navigating the critical phases of pregnancy, postpartum and beyond. The app already connects to more than 50,000 healthcare providers across the country, aiming to simplify the typically fragmented and reactive experience of maternal care.
This funding round includes investment from Palette Ventures, Swizzle Ventures, NEXTBLUE, Suncoast Ventures, Sundial Foundation, and angel investors including Care.com founder Sheila Marcelo, as well as Flo Health’s Yuri Gurski and Andrei Kouzel.
"For too long, women have been left to navigate their health, and their families' health, without adequate tools, support, or information,” said Giraud.
“Trellis Health is changing that, using decades of health history to provide unparalleled context into an individual's health history. We’re building the foundation for generational, proactive consumer health with a private and secure digital health platform that uses AI to translate years of your health context into actionable, intelligent insights paired with innovative care solutions.”
A fragmented experience
Despite advances in medical technology and research, maternal mortality rates in the U.S. remain the highest of any high-income nation, postpartum care remains nearly nonexistent, and managing health through life’s pivotal stages remains an overwhelming and fragmented experience. With more than 100 million people lacking a primary care provider, women are often left to navigate these challenges alone, turning to Google searches, urgent care visits, and fragmented records to manage not only their health but also their families’ health.
Giraud’s personal journey through pregnancy, combined with her experience in genomics and digital health, has helped shape her vision for Trellis Health. Having spent a decade working with some of the largest consumer health data companies, she witnessed firsthand the sheer amount of health data being generated and how disconnected it is alongside outdated - yet compliant - privacy and security practices.
Ultimately, she realized that if we want to rearchitect the healthcare experience and outcomes, we need the full picture - actionable, data-driven insights and lifetime context - and give it directly to the individuals who need it. With Trellis, she is redefining that relationship. Putting women at the center of their own health blueprint to ensure they have the tools, knowledge, and confidence to navigate their health at every stage of life.
“The rapid expansion of wellness offerings, wearables, and digital health tools has created a fragmented landscape, leaving consumers overwhelmed with disconnected data and few trusted resources to make sense of it,” said Rana Taghdisi Argenio, founding partner at Palette Ventures.
“Trellis Health is stepping in at this breaking point, offering an integrated platform that unifies medical history, provides continuous care, and delivers the proactive health management solution that modern consumers, especially women, desperately need.”
Future plans beyond pregnancy and postpartum
While Trellis launches as a pregnancy and postpartum support app, its ambitions stretch well beyond the “bump” stage. Described as a ‘lifetime operating system’ for women’s health, the platform plans to expand its remit to support women through every stage of life, with personalised recommendations, secure medical integration, and expert care partnerships.
