Apprentice Health

A Boston company that clips Bluetooth badges to clinicians and to patients, turns the location trace into a model of how a clinic runs, and rewrites the appointment template around it. Founded 2017, Y Combinator Summer 2018, now listed at two employees.

The badge on the lanyard

A medical assistant clips a plastic tag to a lanyard at the start of clinic. A patient arriving for a urology appointment is handed one at check in. Neither tag is a microphone and neither is a camera. Each is a Bluetooth Low Energy beacon that chirps to gateways screwed to the walls of the rooms that matter: exam rooms, procedure rooms, the waiting area.

That was the setup at Vanderbilt Urology. In the company’s own account of the deployment, “Cloud connected gateways were placed on the walls of rooms relevant to clinical care and patient waiting, and BLE badges were worn by Vanderbilt Urology clinicians and patients.”

What comes out is not a video feed. It is a timeline. The software converts the chirps into “patient wait times, cycle times, interaction duration times, and room occupancy and utilization,” then renders them as a path through the building. One case study screenshot is labeled “Patient journey view: single patient.” That is the resolution: a single appointment, room by room, minute by minute.

From that trace it builds what it calls an operations digital twin, simulates adding a surgeon or sharing rooms, and hands each clinician a scheduling template to accept or refuse.

What a clinic cannot see about itself

Hospitals fly on instruments that do not measure the thing they need. Scheduling systems record what was booked. The electronic record captures what was billed. Neither knows how long a patient sat in a gown, or whether the room next door stood empty.

Apprentice Health puts it directly in its own overview: “Connected sensors are the key to our approach, as the EHR alone contains insufficient operations data to solve some of the most important and intractable problems in healthcare operations.”

The size of the gap is not in dispute. Fierce Healthcare in January 2026 quoted Apella co-founder David Schummers: “In most facilities, OR utilization hovers around 60%, which means between one-quarter and one-third of expensive OR time is going to waste.” Apella, founded 2020, raised $80 million that month and named Houston Methodist and Tampa General as customers. Apprentice Health has worked the same problem for longer, on a fraction of the capital, with one publicly named clinic.

A physician and a data scientist

Rajiv Sivendran holds a BA from the University of Pennsylvania, an MD from Duke and an MBA from Harvard Business School. He trained in internal medicine at Brigham and Women’s Hospital, residency 2011 to 2014 per Doximity, and was an attending there for three years.

The idea predates the company. In 2016 the Rappaport Foundation gave him an award, and its write up is the clearest outside description of what he set out to build: trackers worn on the identification badges of medical assistants, nurses and physicians, with a matching tracker handed to each arriving patient. By then, it wrote, the venture “has already accepted a number of medical centers as clients throughout the U.S.”

His co-founder, Artur Menzeleev, chief science officer, holds a PhD from Caltech and a BA from Penn, and worked as a data scientist on business intelligence, healthcare analytics and IoT.

ClearView MD becomes Apprentice Health

The company incorporated in 2017 as ClearView MD, went through Y Combinator in Summer 2018, and took a seed round that September. When the pandemic closed waiting rooms, the pitch turned to occupancy limits and texted wait times. The Vanderbilt work, and the site that carries it, date from 2020.

Since then the public trail has thinned rather than thickened. Trackers put headcount at two. The about page now carries a warning: “Apprentice Health is not currently hiring. If you are contacted by HR personnel claiming to be representing Apprentice Health, be on alert for possible fraudulent activity.” The Y Combinator listing still shows open engineering roles.

What is proven, and what is still claimed

Read plainly: the idea is sound, the physics is cheap, and one named clinic reports a large result. But every number comes from the vendor, the security claim is a mark rather than a dated report, and the company’s own marketing asserts a peer-reviewed system the literature does not contain. For a product that watches patients and clinicians move through rooms, the absence of any published account of consent, retention or access control is the gap that matters most.

What to watch

• Whether any customer confirms a result under its own name. Vanderbilt Urology is named by the vendor, not by Vanderbilt.
• The peer-reviewed paper the company already claims to have. Publishing it would settle the conflict in one step.
• A dated SOC 2 Type II report with a named auditor, and a published privacy and retention policy for badge traces.
• Headcount and the open roles. The about page says the company is not hiring while the Y Combinator listing shows engineering openings.
