Kyruus Health and the Mystery of the Empty Appointment

Julie Yoo was told to wait more than four months for a specialist appointment. Friends who worked in hospital administration told her something peculiar: the department was operating at only 70% to 80% capacity. There was room, apparently. Just not room anyone could offer her. In her later account of founding Kyruus, this mismatch became the problem worth building a company around.

The doctor was there. The appointment was elsewhere.

Co-founder Graham Gardner had seen another version of the problem. A cardiologist before entering venture capital, he watched patients reach the wrong specialist, receive another referral and begin waiting again. Yoo brought experience in software and data. Together they founded Kyruus in 2010 around what the company calls the patient access paradox.

The founders’ 2018 AWS interview describes referrals influenced by familiarity: doctors sent patients to colleagues they knew, had trained with or shared space with. Perfectly human behavior. A less dependable way to distribute demand across a complicated organization.

There was a business consequence too. As Yoo put it, “there’s also the financial impact on the health system in the form of lost revenue opportunities.” A patient who cannot obtain a useful appointment may take their search elsewhere. The unused slot stays unused; the original hospital still pays to operate it.

The revealing detail is the coexistence of a queue and spare capacity. It suggests a question any operator can borrow: before buying more capacity, can customers discover and use what already exists? In healthcare, that question must also account for clinical suitability. An available doctor is not automatically the right doctor.

An address book that can take a booking

Kyruus Health’s current platform, Kyruus Connect, begins with provider and location data. It ingests, standardizes and maintains records that can feed directories, internal tools and external listings. The company’s expertise sits at the intersection of data management, clinical vocabulary and the operational rules of getting someone through a door.

Consider the difference between a name in a directory and an appointment you can use. A name answers “Who works here?” Booking requires more: what care is offered, where, for whom, and at what time. Each extra condition is an opportunity for information held in separate systems to disagree.

The Schedule product connects to electronic health records to expose appointment availability. Pre-booking questions help route people appropriately. Search supports finding providers; APIs let organizations build experiences around the information. These are tools for healthcare organizations, whose websites and other channels become the patient’s point of entry.

That positioning helps explain the competitive field. Optum Patient Access and Engagement, formerly DocASAP, overlaps with parts of the offering. A hospital can also use scheduling features within its existing EHR. Consumer booking marketplaces address discovery from another direction. Kyruus’s distinctive proposition is maintaining the provider information that can travel across organizational boundaries and support several access channels. Whether that breadth justifies another vendor depends on the buyer’s existing systems and actual problem.

The mammogram hiding in the wrong search

A 2025 customer case study provides a useful test. An unnamed health system with more than 5,000 providers rebuilt its provider data and connected search and scheduling to Epic. Kyruus reports a threefold increase in average monthly online bookings, reaching more than 10,000 a month.

The more instructive result was smaller. Analytics showed preventive mammogram demand going to the wrong provider type. The team changed the routing to mammogram-specific providers or locations. Nearly 1,000 mammogram appointments a month were then booked online.

The failure was in how the service had been represented and routed. More traffic could simply have delivered more people to the wrong destination. The evidence changed the configuration. For anyone managing an online service, this is a practical habit to copy: inspect unsuccessful searches, and follow them all the way to the action the person wanted to complete.

The bill for making things simpler

The business model is B2B software as a service. Health systems, medical groups and health plans buy the tools; patients and members encounter the resulting experiences. The customer’s return can come from acquiring patients, reducing administrative work or putting appointment inventory to better use. Those benefits need measurement against implementation and ongoing operating costs.

There is also a visible capital bill. Kyruus announced $42 million in Series D financing in January 2020, led by Venrock and Highland Capital Partners. That June, Francisco Partners supplied another $30 million. Building the connections behind an easy appointment required substantial investment.

A customer result makes the economics more concrete. Kyruus reports that Northeast Georgia Health System booked 2,000 appointments in its first six months of online scheduling, with 75% attributed to new patients, and that the technology paid for itself in less than a year. That is a named deployment’s reported experience, rather than a universal payback period.

By February 2025, Kyruus said it had been profitable since 2023 and projected more than $150 million in annual recurring revenue for 2025. ARR is a recurring-revenue measure; the figure was a projection. It nevertheless indicates why this unglamorous part of healthcare attracted investors.

Following the patient beyond the hospital website

The company’s expansion follows the places where a patient’s task continues. The HealthSparq combination, announced in December 2020 and subsequently described as a 2021 acquisition, brought health plan navigation and cost transparency into the picture. Insurance directories matter because patients do not necessarily begin on the hospital’s preferred website.

The 2022 Epion Health acquisition extended the work into intake and engagement. Today, Check-In lets patients respond to a text, supply insurance information, complete forms and make payments without needing a new portal login for that workflow. Finding an appointment is only the first administrative chore.

Reach, launched in October 2024, pushes accurate provider listings outward. A Healthgrades partnership announced in October 2025 adds profile maintenance and review management on another destination patients already use. A directory’s usefulness depends partly on whether its information survives the trip beyond the organization that maintains it.

Kyruus describes a remote-first culture with offices in Boston and Portland, and employee groups that work on the employee experience. Its published values include respect and accountability. The photograph supplies a more entertaining glimpse: people leaning over a branded jigsaw puzzle, an unusually literal activity for a company in the matching business.

Then the journey reached the bill. In September 2025, RevSpring announced an agreement to acquire Kyruus. Current company materials identify it as part of RevSpring. The stated plan joins search, scheduling and transparency with engagement and payments. The strategic logic is easy to follow: a patient experiences these as successive tasks, even when different departments own them.

Start where the records disagree

For a healthcare buyer, the useful starting exercise is to trace one real care request across the directory, scheduling rules and intake process. Give responsibility for maintaining the underlying records to someone who can resolve disagreements. Connect the systems. Measure suitable bookings and the staff work they replace. Then widen the channels that expose those appointments.

An empty slot is useful only when the right person can find it.

The lesson of the access paradox

The conditions matter. Software cannot conjure a specialist who is genuinely unavailable. Unmaintained records, restrictive booking rules and incomplete integrations can frustrate a polished interface. A November 2025 survey commissioned by Kyruus, conducted by Wakefield Research among 100 senior U.S. health plan leaders, found 85% struggled with inaccurate provider data. The company’s own research keeps bringing the argument back to the records.

Yoo’s original predicament remains a good diagnostic question. When someone says there is no appointment, does the organization know that - or has it merely failed to find one?
