Keas
Keas was made to help companies improve the health of their employees.
The site creates personalized health plans for members, including advice on diet and exercise and SMS and email reminders. Keas is not open to consumers - only to business clients.
Keas' founder, Adam Bosworth, says Keas will have a health plan collection similar to Apple's App Store. Medical experts can add health plans to the site they have designed. If users purchase one of these plans, Keas takes a cut of the revenue and passes the rest onto the plans designer.
