LETWESAF was born out of a real-life bear attack in the wilderness. A couple lost their lives while sleeping, despite taking all the standard safety precautions. Deeply affected by the tragedy, our founder — an avid camper himself — set out to create a radar-based alert system that would truly allow people to sleep in peace and wake up safe. LETWESAF is where technology stands guard, protecting life in the wild.
