TreadShare is a mobile app that connects drivers and riders so they can easily organize carpools in just a few clicks — with key features like a cost-sharing agreement, user profiles, and in-app messaging. The goal: help people save money, meet like-minded travelers, and reduce traffic and carbon emissions.

In 2025, we’re launching a new private carpool group feature to help organizations address Scope 3 emissions from employee and visitor travel. Designed for mountain towns, this feature also serves cities, events (like concerts and marathons), universities, and businesses looking to promote sustainable transportation within their communities.
