Rally Health is all about putting health in the hands of the individual. It’s our mission, and it drives everything we do, which is to empower people with easy-to-use online and mobile tools that help them take charge of their health and health care, from improving their diet and fitness to selecting health benefits, and choosing the right doctor at the right price for their needs.

Our culture is built on a deep and sincere commitment to helping people live healthier lives. To do this, we are committed to innovating at every level. As our president and COO David Ko says, “We are a company that continuously innovates. It cannot end. It has to be in everything we do, which means that some of the things we’re going to do are not going to work – and that’s okay. We’re not trying to build something that is churn and burn. We’re building something that follows consumers over their lifetime.”

On the rewards and incentives team, you will have the opportunity to work with systems at massive scale, on products that have a positive impact on society. We're all about rewarding people for healthy behavior -- from preventive health and wellness to condition specific management, we provide rewards and incentives for actions and behaviors that improve health outcomes and lower healthcare costs for the consumer.
