Sessions is a personal exercise coaching program that uses SMS and email to provide support, accountability, and encouragement to help people build sustainable exercise habits. The company was founded by Nick Crocker after he became frustrated with the healthcare system in 2010 and wanted to use his experience in technology and behavior change to create a more effective way to promote healthy living. Sessions pairs users with personalized coaches who create customized plans based on individual needs, and uses text reminders to help users stay on track. The company is using Twilio's SMS platform to deliver these messages, and is currently launching its third version of the product and completing further clinical piloting to validate its model. By combining technology and behavior change, Sessions aims to make it easier for people to exercise and live healthier lives, particularly those who are too busy or have difficulty accessing traditional healthcare services.
