Our Vision: “Making premium education affordable”The level of personalized attention required during the formative years is lacking in most schools, except for a few premium ones. Moreover, most parents, especially working professionals, often find it difficult to find time to compliment their kids learning in school. A rather serious implication of this is that children whose development lag behind during their early years find it very difficult to catch up in their higher classes. Through Toffee Ride, we attempt to bridge this gap using technology as an enabler to provide the much-needed personal attention in early learning.
