About Us

With over 10 million active families and $90 million in venture funding, Life360 is the world’s largest mobile app for families. Today, we are very focused on location sharing and safety, but our mission is to become the must-have Family Membership that gives families peace of mind anytime and anywhere.

Our team is focused on building technology that helps families feel safe and together even when they are outside of the home and apart. From personalized location-based alerts that help make daily coordination easier, to advanced sensor tech that can detect if you are in a car crash and automatically send you an ambulance, we are leveraging smartphones to their fullest extent to reinvent how families get through the day.

You will be joining Life360 at a key moment in our history. We doubled active users and tripled revenue in 2017, and we are scaling our team to accommodate this rapid growth. We currently have 75 full-time employees, with offices in San Francisco, Las Vegas, and San Diego.
