Stakeholders
We have three major stakeholders:
    1.
    Public health agency (PHA) planners at both the country and regional level
    2.
    Organizations with large campuses
    3.
    Citizens (including vulnerable populations)
1. Public health agency (PHA) planners at both the country and regional level
For PHAs, we create a data-rich stream of citizen activity to fill the gaps and complement other data-gathering efforts to understand case rates, the severity of symptoms, equitable deployment, and effectiveness for vulnerable populations.
2. Organizations with large campuses
For organizations with campuses (i.e. universities or large employers), the decision-makers usually take the lead in adopting innovation and expensive solutions to ensure safety, encouraging adherence to procedure (e.g. frequent testing), maintaining continued operations, and managing incentive programs (e.g. automatic sick leave). A significant frustration amongst these leaders is waiting for city or state solutions.
3. Citizens (including vulnerable populations)
For citizens, early exposure alerts, personalized risk scores for activities based on their health conditions, and visualizing local pandemic spread are critical. For vulnerable populations, our solution works for citizens without a smartphone. We developed a paper-based QR code with cryptographically tamper-evident digital signatures for citizens to engage in the test-trace-treat-vaccinate ecosystem without disclosing any personally identifiable information.
​
Further, for public planners, we have already worked with dozens of U.S. states and regions to understand their covid response needs. Seven have deployed PathCheck open-source Exposure Notification software that is now used by millions. We use these relationships as well as the fact that we are a trusted non-profit spinout of MIT to understand their future needs about anticipating and responding to the next pandemic and any future COVID-19 spikes.
We actively seek feedback on ideas, designs, and prototypes from planners and residents to prioritize our feature development, reduce deployment risk and maximize health impact. For residents, we especially work on willingness-to-use (incentives, UI/UX, etc.).
We have deployed our exposure notification app in seven places - https://www.pathcheck.org/en/covid-19-exposure-notification-app​
