Overview
Mainstay
Mainstay helps you bridge the gap between your organization and the people you serve through purposeful, AI-driven conversations. Originally built to help students navigate the complexities of college, the platform now supports both higher education institutions and modern workplaces. You can use its behavioral science-backed messaging to proactively reach out to individuals, answer their questions instantly, and guide them toward important milestones like enrollment or employee onboarding.
The platform focuses on boosting retention and engagement by meeting people where they are—on their phones.

Beyond simple caller ID, you can use the platform to manage your dialer, send flash messages, and even record important conversations. It serves over 400 million active users globally, making it a vital tool for anyone looking to eliminate phone-based harassment. Whether you are a professional protecting your work hours or a casual user avoiding scams, the software provides a layer of digital trust for every incoming notification.
