Ultralight, a software platform built for functional, integrative, and longevity medicine practices, has closed a $9.3 million seed round to consolidate the patchwork of tools that most clinics in this space currently rely on. The company was co-founded by Sunita Mohanty and Pedro Tabio and describes its product as a single operating system for physicians focused on root-cause and preventive care.
More doctors are leaving hospital systems and large clinical networks to open independent practices centered on personalized medicine. Their patient base is growing with them. A 2025 NEJM Catalyst survey of 525 clinicians, clinical leaders, and healthcare executives globally found that 60% reported integrative care use within their organizations was prevalent or extremely prevalent, and 80% said patient outcomes were better or significantly better compared to the general population. Demand for this type of care is increasing. The software supporting it has not.
The seed round was led by The General Partnership, with participation from Wisdom Ventures, Anthemis, Emerson Collective, and GSBackers, among others.
Functional and integrative medicine works differently from conventional care. Physicians spend more time with each patient, order broader diagnostic panels, and track health across multiple body systems over longer time periods. The core problem is that existing software was not built for any of that. Most electronic health record systems were designed for short, high-volume appointments driven by insurance billing. They manage notes and invoices well enough, but they were never built to integrate wearable device data, track how symptoms change over months, or connect a patient's lab results from one visit to decisions being made in the next.
What that leaves, according to Ultralight, is a clinic running on five or more disconnected tools at once: one for scheduling, another for documentation, others for lab results, patient communication, and treatment protocols. None of them share data automatically. The physician ends up doing that manually, which takes time away from patient care.
"Personalized medicine is crossing the chasm, driven by clinicians leaving legacy systems to build independent practices and by patients demanding deeper, root-cause care. We believe Ultralight can become the system of record for this shift: a single, AI-native platform that integrates the clinical and operational silos that have held modern care back." — Phin Barnes, co-founder and Managing Partner, The General Partnership.
The funding will support three priorities. First, Ultralight plans to deepen what it calls its clinical intelligence layer, an AI-assisted feature that helps physicians process complex patient data and surface care recommendations. Second, it will expand its library of treatment protocols. Third, it will build a dedicated sales team. The company says patient demand has already outpaced what the founding team can handle without additional staff.
Ultralight also intends to support more complex clinic structures. That includes multi-location networks and practices that operate under hybrid billing, meaning they accept both insurance and direct cash payments from patients. Hybrid billing is administratively complicated, and it is an area where many existing platforms fall short.
The company operated under the name Vibrant Practice before rebranding to Ultralight alongside this funding announcement. Since its 2025 launch, the platform has been adopted by 75 clinics across the United States, all through word of mouth within clinician communities. More than 1,200 clinicians are currently using it. Roughly 60% of new customers are switching from existing systems entirely rather than adding Ultralight as a secondary tool.
The platform pulls clinical data, workflows, and AI-assisted analysis into one place. Before a patient visit, a clinician can review labs, wearable trends, symptom history, and relevant care protocols from a single screen, without switching between applications. The system draws on a proprietary knowledge base reviewed by clinicians to support personalized recommendations across different body systems.
Mohanty's path to founding the company started with her own health. After receiving a diagnosis of an autoimmune condition and being told surgery was her only option, she sought a diagnostics-focused approach and reached full remission within eight months. She then spent a year working closely with physicians practicing this style of medicine, and saw how much of their time went to manually reconciling data between tools. Tabio came to the same problem from the technical side, having led engineering at Stride Health, where he observed how fragmented and outdated healthcare infrastructure had become.
"Doctors are rediscovering the medicine they went into the field to practice — and then finding out the software doesn't exist to support it. We built Ultralight to be the system they should have had from day one." — Sunita Mohanty, co-founder and CEO, Ultralight.
Alongside the rebrand, Ultralight has assembled a clinical advisory board that includes Dr. Jordan Shlain, Dr. George Papanicolaou, Dr. Brian Hollett, and Dr. Alexis Gonzales, all practitioners working in functional, integrative, or longevity medicine.
The $9.3 million seed round is the first funding Ultralight has publicly disclosed. The General Partnership led the round, with Wisdom Ventures, Anthemis, Emerson Collective, and GSBackers also participating.
The company reached 75 clinic customers and more than 1,200 active clinicians before raising external capital. For a seed-stage software company, that level of organic adoption before a first funding round is uncommon.
