An ounce of prevention is worth a pound of cure

ReturnSafe is transforming healthcare through the power of prevention. We do this by enabling risk-bearing organizations and owners of shared spaces including employers, schools, concert venues, sports arenas and more to keep these spaces open and their occupants healthy, well and safe with preventative and early detection measures. This is fundamentally important because it aligns prevention with business continuity and profit!

Why choose ReturnSafe?

The company was created to address COVID-19.

The entire company is 100% focused on our mission to prevent infectious disease outbreaks.  This is a new type of problem and a new type of problem requires a new company, not just a re-skinning of existing tools.

Holistic approach, combining Screen, Test and Trace

More than the sum of the parts.  A screening app is not enough.  Screening and testing data drive workflows and processes such as contact tracing, and quarantine management.

A pragmatic approach to privacy

Privacy is a fundemental right and no one should have to give up their privacy for their paycheck or reveal personal health information to someone that doesn’t absolutely need it.

ReturnSafe is a public benefit corp, mission over purpose.

We started as a non-profit.  Our mission to prevent outbreaks at schools and offices is sacred, above profits.  We use the revenue as we generate to make our products better and offer 80% discounts to schools, nursing homes and non-profits.

An enterprise-grade system with a human-centric design. 

We know you need a secure, compliant infrastructure that checks all the boxes for enterprise IT, but we also need to make staff & students FEEL stafe when they return to campus and want to participate in keeping the community safe.  

Need for a BioSecurity Platform vs. ‘Screening App’

A screening app is a point solution that doesn’t truly address the need to create a safety bubble around offices or campuses.  ReturnSafe provides the core app and integrated workflows out of the box and integrates with your existing infrastructure and industry-specific solutions to bring all the data together to enable a safe campus.
