We are passionate about making healthcare more accessible for anyone who needs it.

Born out of frustration

Overlap was founded in May 2016. We were born out of a frustration with lack of a complete services to help healthcare organizations deliver value to patients so they can lower costs and improve health access.

Improving healthcare has no borders.

Our headquarters are in California, but we are a distributed company with team members in 5 different countries speaking 13 different languages. Overlappers (as we like to call ourselves) are free to live and work wherever they want. Our common goal, the thing that binds us, is to build good technology that promotes greater health equity.

Open-source in our bones.

We believe in open source and are the main contributor to the Open mHealth data standard. So much that we use a lot of the Open mHealth tools and data formats to make your health data as easy as possible to use.

Here to serve.

If you have a general question for us, just drop us an email at hello@overlaphealth.com and we’ll get back to you as soon as we can. If you’re a client, and you want to talk to someone in customer service, send an email to support@overlaphealth.com.

You can stay up-to-date on our thoughts on healthcare, technology, design and business on our blog. You can also follow us on Twitter @overlaphealth and Facebook.
