SAN FRANCISCO — Ultralight, a healthcare technology startup focused on preventive and personalized care, has raised $9.3 million in seed funding to develop an AI-powered operating system designed for clinicians in functional, integrative, and longevity medicine.
The funding round was led by The General Partnership, with participation from Wisdom Ventures, Anthemis, Emerson Collective, and GSBackers. The company aims to replace fragmented medical software systems with a single platform tailored to newer models of care that emphasize root-cause treatment and long-term patient outcomes.
Ultralight’s platform integrates patient data — including medical records, lab results, wearable device data, and symptom tracking — into a unified system. It also includes a clinical intelligence layer, built on a proprietary knowledge base, to help physicians analyze complex information and generate personalized treatment insights.
“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 co-founder and CEO Sunita Mohanty. “We built Ultralight to be the system they should have had from day one.”
The company was co-founded by Mohanty and Chief Technology Officer Pedro Tabio, who previously led engineering at Stride Health. Mohanty said her own experience with an autoimmune condition, and subsequent recovery through a personalized treatment approach, inspired the company’s creation.
Since launching in 2025, Ultralight has been adopted by 75 clinics and more than 1,200 clinicians, growing primarily through referrals within medical communities. The company said about 60% of its customers are replacing existing software systems entirely, indicating strong demand for a unified platform.
“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,” said Phin Barnes, co-founder and Managing Partner at The General Partnership.
Clinicians using the platform say it reduces administrative workload and allows for more patient-focused care.
“Ultralight has allowed me to do what I think I do best — and that’s being fully present with my patients,” said Dr. Dannette Kallay.
The company said it will use the new funding to expand its clinical intelligence capabilities, broaden treatment protocol coverage, and build out its sales team. It also plans to support more complex practice models, including multi-location networks and hybrid insurance and cash-pay systems.
Ultralight also announced it has rebranded from its previous name, Vibrant Practice, and has formed a clinician advisory board that includes leaders in functional and integrative medicine.
