IOS will now manage Saina's endorsements, appearances, brand profiling, patents, licensing and digital rights, images and visibility on social networking sites.
The London Olympic bronze medallist had recently won a silver at the Badminton World Championship in Jakarta and today once again regained World No.1 spot.
IOS will target around 25 crore over the two years.
"I have been performing well in the international circuit but at the same time I was looking for a sports management group that could manage my overall brand portfolio and logistics plus commercial activities in the best professional way.
IOS also manages other elite sportspersons such as cricketer Suresh Raina, Olympic medallist boxers Vijender Singh and MC Mary Kom, and two-time Olympic medal winning wrestler Sushil Kumar.
Commenting on the deal, Neerav Tomar, MD & CEO IOS Sports & Entertainment said, "I would like to congratulate Saina for making the nation proud by winning historic silver medal in the World Championship and regaining the world number 1 spot. We are pleased to welcome another top women sportsperson of the world into the IOS family.
