Keeping What Matters Close

Tethera Technologies is building medTether — a paired proximity alert system that ensures life-critical medications stay within reach of the children who need them.

What We're Building

A new kind of safety net for families managing life-threatening allergies and asthma

medTether is a paired proximity alert for life-critical medications. A small tag attaches to rescue medication like an EpiPen or inhaler, and a wearable is worn by the child. The child can customize the wearable to match their favorite colors and style. If the two separate, both devices sound an alert — no smartphone required, no charging needed.

Parents can optionally receive escalation alerts via app, SMS, or phone call with location information for added peace of mind.
