About OneHaven

Protecting What Matters Most – Online and Beyond

At OneHaven, we’re on a mission to safeguard children, seniors, and individuals from today’s digital threats — from online predators and scams to mental health and screen time concerns.
We’re not another tech startup chasing buzzwords.
We’re parents, caregivers, and tech experts who have experienced these threats—and built the protection we all needed.
We believe safety shouldn’t be an afterthought in the digital age.
That’s why we built OneHaven: an intelligent protection platform designed to give caregivers and individuals
peace of mind, control, and real-time insights — all in one place.
