About Primary.Health: Built by people who were in the field

We started as volunteers in 2020. Today we build shared infrastructure for immunization and public health: everyday workflows done with excellence, ready to reconfigure for the next response.

Our story

From a folding table to shared infrastructure

  1. 1

    Spring 2020 · A group of volunteers

    Researchers at the University of California, San Francisco needed to answer a question no one could: how much COVID was actually in the community? They had the science. They needed a way to register thousands of people on a sidewalk, track every sample, and return results quickly, in a year when results still traveled by fax. So we built it.

  2. 2

    April 2020 · The Mission and Bolinas

    In one week we ran the data system, patient portal, and lightweight EHR behind community-wide testing in a census tract of San Francisco’s Mission District and across the rural coastal town of Bolinas. Volunteers in borrowed PPE, a tent, a folding table, and results returned to each person in their language, with a clean dataset for researchers every night.

  3. 3

    2020–2021 · Data that changed the response

    The findings showed far more infection than case counts suggested, falling hardest on essential workers who couldn’t stay home. That work helped shape San Francisco’s Right to Recover program. The partnership went on to serve more than 100,000 people and ran one of the first community-scale variant surveillance efforts.

  4. 4

    Incorporated · Built to last

    Once it was clear this would be needed for a long time, the volunteer team became a company with the same instinct: run a fast, well-designed response at scale while the question is still open.

  5. 5

    The height of the response · About 200 people

    As programs spread across states, the team grew to about 200 people at the peak. Many of them ran testing and vaccination operations side by side with our partners, and their work is a big part of why those programs held up when it mattered.

  6. 6

    After the emergency · A deliberate reset

    As emergency programs wound down, we made the hard choice to become a much smaller company of about 20 people, focused on the software that would outlast the emergency. We remain grateful to everyone who carried that work with us.

  7. 7

    Today · A lean team, growing again

    About 30 people and growing: a lean, skilled team of engineers, integration specialists, and public health operators who have run this work at scale, built for the work ahead rather than the overhead of the last emergency. We remove access barriers to immunization and fix provider workflows, run public health labs, newborn screening and case management, and bring schools into the public health system, all on shared infrastructure that reconfigures for the next response.

What the field taught us

Why we build the way we do

Pathogens move quietly

Disease can spread for weeks before it shows up in case counts. Surveillance teams need data systems that keep up with them.

Tools fail, not people

In 2020, public health teams did extraordinary work with systems that weren’t built for the scale they faced.

Shelf-ware goes stale

Preparedness funding often covers plans and exercises, but rarely the infrastructure that has to be live on the day something happens.

Readiness has to be useful every day

Response capacity holds up best when it’s used for routine work: immunization, labs, case management, schools.

Trust is hard to rebuild

Systems holding the public’s health data have to be accurate and secure from the first day of a response.

Choose partners in advance

In 2020, partners were chosen under extreme time pressure. Selecting and testing them on a normal timeline leaves room for real due diligence.

Primary.Health’s Mission

To reduce the spread and severity of disease by making diagnostics, immunization, and preventive care simple and affordable to deliver at scale.

Mission-driven

We began as volunteers supporting one community’s response, and we still judge our work by what it does for the communities our partners serve.

Evidence-based

We start from the evidence, measure what our tools change, and publish with research partners when we can.

Partnership-oriented

Our success is credited to the many organizations and businesses who share our vision and focus, and we’ll keep growing through partnership with communities, businesses, and public health.
