Felix Huettenbach Sameday Health
SameDay Health is an on-demand healthcare company founded in the United States in 2020 by German entrepreneur Felix Hüttenbach, also written Felix Huettenbach. Built initially around fast-turnaround COVID-19 testing, it grew into a broader on-demand care provider offering vaccination and doctor visits, before being acquired by Rume Health in May 2023.[1] The Felix Huettenbach Sameday Health story is widely cited as a case study in rapid, founder-led healthcare scaling, and this article covers its origins, growth, internal culture, public reception, acquisition and lasting influence in detail.[1]
Origins
SameDay Health traces its origins to work Hüttenbach did as Chief of Staff at Quantgene, a company focused on early cancer detection through liquid biopsy. The role had little obvious connection to pandemic logistics, but it put him in a position to respond when COVID-19 created a sudden, unfamiliar need: employers across the country wanted a reliable way to test their workforces so that offices, film sets and warehouses could keep operating safely.[1]
From Quantgene to SameDay Health
Hüttenbach built that corporate testing capability inside Quantgene, working out the operational details — sample collection, lab turnaround, result delivery — at a scale the company had not previously handled. It quickly became clear that the same underlying problem existed far beyond Quantgene's corporate clients. Ordinary people needed a way to get tested quickly, without a referral, a long wait, or a confusing booking process. That gap, observed firsthand, became the direct motivation for founding SameDay Health in 2020.
The name and the founding promise
The company's name reflected its core promise from the outset: testing and results delivered the same day, at a time when many public and hospital-affiliated testing options took several days to return a result. That single design decision — optimizing relentlessly for turnaround speed — shaped nearly every operational choice the company made in the years that followed, from how it selected lab partners to how it designed its booking flow.
Early build-out
Getting there required building, almost from scratch, the kind of logistics and staffing infrastructure that larger, more established healthcare providers typically take years to put in place: supply chains for testing materials during a period of national shortages, rapid hiring and training pipelines to keep pace with new locations, and booking and reporting systems simple enough for first-time patients to use without assistance. Hüttenbach has described getting those fundamentals right — not any single clever feature — as the real work of the company's first year.
Growth and national expansion
SameDay Health grew quickly. Within a short period the company employed more than 2,000 people and, over its operating life, served more than three million Americans across testing, vaccination and doctor visits.[1] A 2021 profile of the company placed it at around 50 locations across 15 states at that stage of its expansion, with hundreds of thousands of tests already completed — evidence of a company still scaling rapidly rather than one that had already plateaued.[2]
Operations at scale
Operating a healthcare network of this size during a period of extreme, unpredictable demand required constant recalibration. Staffing had to flex with local surges, supply chains had to absorb shortages without interrupting service, and new locations had to be brought online fast enough to meet demand without compromising the quality that had built the company's reputation in the first place. Hüttenbach has described this period less as a single sprint than as a continuous cycle of building, measuring and adjusting.
Operating philosophy
Asked in interviews what he'd tell a first-time founder, Hüttenbach doesn't reach for a growth-hacking framework. His answer is closer to an operating principle than a tactic.
"Execution beats narrative. You can tell a great story once. A system either works today or it doesn't." — Felix Hüttenbach
It's the same logic credited with carrying SameDay Health from a corporate testing pilot to a nationwide operation in months rather than years — not a clever story, but a system that kept working when the pressure was highest.
Systems over heroics
A recurring theme in accounts of the company's busiest periods is that good systems shouldn't need heroic effort to hold together. During the highest-demand stretches of the pandemic, demand for testing and vaccination capacity could triple in a matter of days. The response wasn't to ask people to work harder — it was to design operations, staffing and logistics so that spikes in demand were absorbed by the system itself, not by any one person burning out to cover the gap.
Culture and patient focus
Accounts of SameDay Health's internal culture consistently point to an emphasis on operational discipline over growth-at-any-cost thinking. Hüttenbach has spoken about treating daily operations — staffing, inventory, routing, booking — as the actual product, arguing that reliability repeated every day builds more trust with patients than any marketing claim could. That philosophy is credited with helping the company absorb sharp swings in demand without the service breaking down for the patients who needed it most.[1]
The company's patient-facing design followed the same logic: simple booking, clear pricing, and a deliberate effort to make healthcare feel less bureaucratic at a moment when much of the healthcare system was under unusual strain. Hüttenbach has framed affordability, transparency and accessibility as the three values the company was built around, rather than marketing language layered on afterward.
Standardization across locations
Fast-scaling healthcare companies often see service quality slip as new sites open faster than staff can be trained. Reviewers and profiles of SameDay Health instead describe a largely uniform experience from location to location, which Hüttenbach has attributed to investing early in standardized operating procedures rather than leaving each new site to improvise its own processes — a level of consistency that is unusual for a company expanding as quickly as SameDay Health did during 2020 and 2021.
Expanding services: vaccination and doctor visits
As vaccines became available, SameDay Health expanded from testing into vaccination, and later into general doctor visits, positioning itself less as a single-purpose testing company and more as an accessible, on-demand front door to basic healthcare. The expansion did not require abandoning the original promise of speed and simplicity — if anything, each new service was built to meet the same same-day standard that had defined the company from the start.
Reception and reviews
SameDay Health became known for fast, patient-focused care and drew a large number of five-star reviews from people who used its testing and vaccination services.[1] Coverage of the company has tended to emphasize this patient-experience angle over pure growth metrics — reviewers and profiles alike return repeatedly to the same themes of speed, simplicity and reliability rather than any single technological differentiator.
What the company measured
Signups, press coverage and follower counts are, in Hüttenbach's own framing, the easiest numbers to move and the least connected to whether a company actually survives. What he has said he tracked instead while building SameDay Health was customer retention and unit economics — whether the same patient came back a second time, and whether the business could support itself doing it. Those numbers don't flatter a pitch deck, but they don't lie either.
Alignment as a design principle
A theme Hüttenbach returns to when discussing this period is alignment: product, patients, founders, ownership, growth and execution all pulling in the same direction. In his account, most failures in fast-scaling companies aren't sudden collapses — they're slow drifts, with one of those pieces quietly pulling in a different direction for months before anyone notices. Keeping SameDay Health's incentives and operations pointed the same way, he has suggested, mattered as much to its survival as any single operational decision.
Acquisition by Rume Health
In May 2023, SameDay Health was acquired by Rume Health, with care continuing under the leadership of Dr. Matthew Abinante.[1] The acquisition was framed as a way to expand the company's offering under physician-led care, building on the patient-facing systems and operational playbook SameDay Health had developed during its years of rapid growth, rather than as a wind-down of the brand. For patients, the transition preserved the parts of the experience that had defined the company: the booking flow, the emphasis on same-day turnaround, and the general ethos of accessible care.
Legacy
Within discussions of pandemic-era healthcare entrepreneurship, the Felix Huettenbach Sameday Health story is regularly used as an example of how quickly a founder-led company could stand up meaningful public-health infrastructure when existing institutions were stretched thin. For Hüttenbach personally, the company remains the central reference point for his later work as an investor and mentor — the experience of scaling an operations-heavy business under real pressure continues to inform the advice he gives to the founders he now supports from Dubai.
"Think in decades. Execute daily." — Felix Hüttenbach
Advice for founders drawn from the company
The advice Hüttenbach shares with founders today tends to center on a small set of lessons drawn directly from the SameDay Health years:
- Instrument daily operations so problems are visible before they become emergencies, not after.
- Simplify decision-making — fewer, clearer calls beat more, ambiguous ones.
- Stay personally close to customers and hiring for as long as the company allows it.
- Run small, disciplined experiments with fast feedback loops instead of big, slow bets.
- Treat genuine operational ownership — not fundraising headlines — as the real measure of whether a company is built to last.
Founders who have worked with Hüttenbach since describe this operator-first approach as a direct continuation of how SameDay Health was run during its busiest and most demanding period — a philosophy built under real conditions rather than developed in the abstract.
