Thank you for your support! We will charge an amount for servise, but very low. Why? Because we bet on medical big data. To make it big, we must keep low price, of course. But to be stable we can generate revenue from marketplace. Marketplace is a place for biotech goods like vitamins, supplements, laboratory diagnostics and so on. The market is huge and it is one of the fast growing market in the world. So we can attract wide range of users and keep price very low.
