Built for organizers.
You bring people together. We help you plan the work.
Why we built it
An event needs more than a list of names. Each person needs a job and a time, and the organizer needs to know who is coming.
Proximatic turns event notes, people and available times into a roster you can use. It works for event crews, clubs, tournaments, volunteer programs, classes and community groups.
Give Proximatic the event, people list, shift ideas, teams, availability and supported rules in one message. It can prepare the setup and roster, then help publish, email assigned people and manage attendance signs. You review changes and approve the actions. Billing stays in the web app; participants still confirm their own signup and attendance.
Build my rosterOur Core Beliefs
Clear pricing
Simple event pricing, with the cost shown before you pay.
Clear next steps
Volunteers should be able to see the job, choose a shift, and know where to go.
Privacy is Non-Negotiable
Attendance records check-in and checkout, not continuous location. We do not sell volunteer data.
Built for Human Beings
Respecting your time means building tools that are intuitive. We design for the exhausted coordinator.
Our Promise
Keep the everyday tools free, make paid options clear, and help organizers spend less effort keeping separate lists up to date.
