Ultralight replaces fragmented medical software with a single AI-native system, built for functional, integrative, and longevity practices
SAN FRANCISCO–(BUSINESS WIRE)–Most doctors went into medicine to help people. But the system they entered wasn’t built for that — high-volume visits, fragmented records, treat the symptom and move on. Over time, a growing number of physicians have gotten disillusioned and started asking a harder question: what if I could practice medicine the way I originally intended?
That question is driving a movement. Functional, integrative, and longevity medicine is one of the fastest-growing segments of practice formation in the U.S., fueled by clinicians who want to treat root causes and patients who want more than a prescription. But the clinicians building this future are still running on infrastructure designed for the system they left behind — stitching together five or more disconnected tools that were never built for how they practice.
Ultralight, an AI-native operating system for preventive and personalized care, today announced it has raised $9.3 million in seed funding to change that. The round was led by The General Partnership, with participation from Wisdom Ventures, Anthemis, Emerson Collective, and GSBackers among others.
Ultralight co-founder Sunita Mohanty’s path to the company started with her own health. After being 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 8 months time. The experience showed her both what modern medicine could look like and how few patients ever get access to it. She spent the next year embedded with the physicians delivering this care and discovered they were spending hours each week as their own data integrators — copying between tabs, reconciling disconnected systems, doing everything except the medicine they’d set out to practice.
“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, saw the same infrastructure gap from the technical side while leading engineering at Stride Health, where he experienced firsthand how fragmented and outdated healthcare systems had become.
Ultralight gives clinicians a single system built around the full patient story — not just notes and labs, but wearable data, symptoms tracked over time, and treatment protocols that connect across visits. Instead of toggling between five tools to prepare for a complex case, a clinician can walk into a patient visit with everything synthesized in one place. A built-in clinical intelligence layer — powered by a clinician-reviewed, proprietary knowledge base — helps physicians synthesize complex data and surface personalized care insights across body systems.
Since launching in 2025, Ultralight has been adopted by 75 clinics, growing entirely through word of mouth within tight-knit clinician communities. More than 1,200 clinicians have discovered the platform and are using it to reduce administrative burden, automate documentation, and ultimately spend more time with patients. Approximately 60% of new customers are replacing existing systems entirely, the strongest signal that Ultralight is solving a problem clinicians have been waiting for someone to solve.
“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
“Ultralight has allowed me to do what I think I do best — and that’s being fully present with my patients.“ – Dr. Dannette Kallay
The funding will be used to deepen Ultralight’s clinical intelligence layer, expand protocol coverage, and hire the company’s first dedicated sales team to serve a qualified pipeline that has outpaced the founding team’s capacity. Ultralight also plans to support more complex practice models, including multi-location networks and hybrid insurance and cash-pay models.
Alongside the funding, Ultralight announced it has rebranded — formerly operating as Vibrant Practice — and has formed a clinician advisory board of leading voices in functional, integrative, and longevity medicine, including Dr. Jordan Shlain, Dr. George Papanicolaou, Dr. Brian Hollett and Dr. Alexis Gonzales.
