“Doctors are rediscovering the medicine they went into the field to practice – and then finding out the software doesn’t exist to support it.” – Sunita Mohanty, Co-Founder & CEO
Personalization has become the baseline expectation of modern life. My shopping recommendations know my taste better than I do. My streaming queue anticipates what I want to watch before I’ve decided. And in my own life, I’ve gone deep: syncing my Whoop data to AI tools, running bloodwork through Function Health, uploading the results to make sense of them, and trying to optimize my sleep, workouts, and calendar around what the data is actually telling me. The infrastructure for personal health optimization has never been more accessible or more sophisticated.
And yet, when you actually walk into a doctor’s office, almost none of that exists.

Healthcare and medicine have largely lagged in delivering this level of personalization, still adhering to a one-size-fits-all model that fails to address what patients increasingly demand: root-cause care, prevention, and a physician who actually knows you. Entrepreneurs obsess over every detail of their business daily, yet the healthcare system takes a snapshot once a year (if that) and assumes that’s our baseline. It’s not surprising that over the past two decades patient dissatisfaction with conventional healthcare has grown steadily alongside a marked rise in chronic and complex conditions that require more individualized support. Consumers are voting with their wallets: out-of-pocket spending on health and wellness is climbing, particularly as interest in longevity and functional medicine intensifies across generations.
The pressure on the provider side is equally acute. Nearly 79% of primary care physicians reported burnout in 2023, driven by administrative overload and a system that actively discourages the kind of care they trained to deliver. In 2023, 39% of physicians surveyed said they were working a side gig: consulting, moonlighting, or exploring entirely new paths. A growing number are finding it by going independent: launching their own functional, integrative, and longevity-focused private practices, where they can finally practice medicine the way they intended. But the infrastructure hasn’t evolved at the pace of patient expectations and clinicians needs. These clinicians, many of whom left legacy systems specifically to escape fragmented, outdated technology, are stitching together five or more disconnected tools that were never built for how they practice.
Enter Ultralight: an AI-native operating system for functional, integrative, and longevity practices that brings clinical data, workflows, and intelligence into a single system. Instead of toggling between tools to prepare for a complex case, a clinician walks in with everything synthesized – wearable data, longitudinal symptoms, treatment history, and a built-in clinical intelligence layer powered by a clinician-reviewed knowledge base.
Ultralight was started by a team with deep expertise across AI, clinical workflows, and go-to-market execution. Sunita Mohanty, Co-Founder & CEO, arrived at this problem as a patient. Diagnosed with an autoimmune condition and told surgery was her only option, she sought out a more personalized, diagnostics-driven approach and reached full remission in eight months. While she led some of the most future-facing products at Meta, from launching Oculus Quest and building smart glasses AI interfaces, to launching Meta’s most successful new consumer app within its incubator, her personal health journey showed her both what modern medicine could look like and how few patients ever get access to it. Sunita is quickly emerging as a trusted voice shaping the future of personalized medicine. Pedro Tabio, Ultralight’s Co-Founder & CTO, saw the infrastructure gap from the technical side, having scaled multi-million dollar health-tech platforms serving complex, regulated markets as Head of Engineering at Stride Health.
The traction speaks for itself. Ultralight has been adopted by 75 clinics growing entirely through word of mouth within tight-knit clinician communities. Chart prep that used to take 45 minutes now takes 10. Admin time has halved. And perhaps most tellingly: 60% of Ultralight’s new customers are replacing existing systems entirely, ripping out what they had and starting fresh.
We are thrilled to have backed Sunita and Pedro from the earliest days, to officially announce our investment alongside The General Partnership, Wisdom Ventures, Emerson Collective, GSBackers and angels Jonathan Swerdlin of Function Health, former Surgeon General Vivek Murthy and Zak Holdsworth of Hint Health, and to continue supporting them as they build the system of record for the future of personalized care.
