Ultralight Raises $9.3M to Arm Doctors in Personalized Medicine Revolt

SAN FRANCISCO, CA – April 17, 2026 – As a growing wave of clinicians departs from the high-volume, symptom-focused world of traditional healthcare, a new AI-powered platform has secured significant funding to build the infrastructure for what comes next. Ultralight, an AI-native operating system for preventive and personalized care, announced today it has raised $9.3 million in seed funding.

The round, led by The General Partnership, with participation from Wisdom Ventures, Anthemis, Emerson Collective, and GSBackers, signals strong investor confidence in a new model of medicine—one focused on treating root causes rather than just symptoms. The funding aims to empower physicians in the rapidly expanding fields of functional, integrative, and longevity medicine, who are currently underserved by outdated and fragmented software.

The Great Resignation of Doctors

The healthcare industry is grappling with a quiet but powerful movement. Disillusioned by a system that prioritizes volume over value, a significant number of physicians are leaving conventional practice models. Burnout fueled by 15-minute appointments, overwhelming administrative tasks, and an inability to practice the deep, investigative medicine they were trained for has led them to seek alternatives.

This exodus is fueling one of the fastest-growing segments of practice formation in the United States. The market for functional, integrative, and longevity medicine is experiencing explosive growth, with some projections showing the global complementary and alternative medicine market reaching over $900 billion by 2034, growing at a compound annual rate of nearly 18%. In the U.S. alone, the functional medicine market is valued at over $66 billion and continues to see double-digit annual growth.

These clinicians are not abandoning medicine; they are seeking to reclaim it. They aim to build practices centered on the full patient story, using advanced diagnostics and personalized protocols to address the root causes of chronic illness. However, in building this future, they have found themselves running on infrastructure designed for the system they left behind.

A System Built on Disconnected Tools

The inspiration for Ultralight began with co-founder Sunita Mohanty's own health crisis. Diagnosed with an autoimmune condition and told surgery was her only option, she pursued a personalized, diagnostics-driven approach that led to full remission in eight months. The experience revealed both the potential of modern medicine and the immense gap in access for most patients.

To understand the problem deeper, Mohanty spent a year embedded with physicians delivering this type of advanced care. She discovered they were acting as their own data integrators, spending countless hours each week toggling between five or more disconnected software tools—one for patient notes, another for lab results, a third for wearable data, and separate systems for protocols and patient communication. They were trapped by the very technology that was supposed to liberate them, doing everything except practicing the medicine they set out to perform.

"Doctors are rediscovering the medicine they went into the field to practice — and then finding out the software doesn't exist to support it," said Mohanty. "We built Ultralight to be the system they should have had from day one."

Her co-founder, Pedro Tabio, recognized this infrastructure gap from a technical perspective during his time leading engineering at Stride Health, where he witnessed firsthand how fragmented and outdated healthcare systems had become.

An AI-Native Operating System for the Full Patient Story

Ultralight is designed to be more than just an electronic medical record (EMR). It is a comprehensive, AI-native operating system that provides a single source of truth for the entire patient journey. The platform consolidates disparate data streams—including clinical notes, complex lab panels, continuous data from wearables, patient-reported symptoms tracked over time, and detailed treatment protocols—into one unified view.

Instead of spending hours preparing for a complex case by copying and pasting between browser tabs, a clinician using Ultralight can walk into a patient visit with all relevant information synthesized and ready. This is powered by a built-in clinical intelligence layer, which uses a proprietary, clinician-reviewed knowledge base to help physicians analyze complex data sets and surface personalized care insights across multiple body systems.

The platform's impact is already being felt. Since launching in 2025, Ultralight has been adopted by 75 clinics and is now used by over 1,200 clinicians, growing entirely through word-of-mouth within close-knit physician communities. A powerful indicator of its value is that approximately 60% of new customers are replacing their existing systems entirely, a clear signal that Ultralight is solving a long-standing and critical problem.

“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 at TheGP

Fueling the Future of Proactive Healthcare

The new infusion of capital will be used to accelerate Ultralight's mission. The company plans to deepen its clinical intelligence layer, expand its library of evidence-based protocols, and hire its first dedicated sales team to manage a growing pipeline of interested clinics. The funds will also support the development of features for more complex practice models, including multi-location networks and hybrid insurance/cash-pay structures.

Alongside the funding, the company announced its rebranding from its former name, Vibrant Practice. It has also formed a clinician advisory board featuring leading voices in the field, including Dr. Jordan Shlain, Dr. George Papanicolaou, Dr. Brian Hollett, and Dr. Alexis Gonzales, ensuring the platform continues to evolve with direct input from the practitioners it serves.

For clinicians on the front lines, the platform represents a fundamental shift in their daily work, allowing them to reconnect with the core purpose of their profession. As Dr. Dannette Kallay, a user of the platform, noted, "Ultralight has allowed me to do what I think I do best — and that's being fully present with my patients.“ This shift from administrative burden to meaningful patient interaction is at the heart of the new paradigm of care that Ultralight aims to power.
