An independent software company in the San Francisco Bay Area, building products where care, privacy, and craft matter.
We build software that helps people understand and use their own health information — private by design, grounded in real clinical records, and honest about what technology can and cannot do.
From embedded software to companion apps, we build for the products people keep close — with the reliability and long service life that everyday devices deserve.
Thylib syncs medical records from patient portals and makes them available — securely, and on the owner's terms — to the AI assistant they already use, so health questions get answers grounded in their real history instead of generic advice.
