"It gives me great joy when international hospitals and healthcare professionals embrace Rabbit Ray as part of their treatment plan. I'm grateful for the mentors who gave me the confidence to venture forward, as well as the incubation space from NUS Enterprise's Social Venture Lab@NUS, which allowed Joytingle to build our products."

- Esther Wang, Founder of Joytingle

While doing volunteer work at a local hospital, Esther Wang noticed many of the children were scared of having their blood taken. She wondered how she could address this issue, and thus began her entrepreneurial journey. Esther leveraged upon the incubation support from NUS Enterprise's Social Venture Lab@NUS and a SG$40,000 grant from the ACE Startup Scheme to set up her social venture, Joytingle.

Their flagship product, Rabbit Ray, is a patient engagement device targeted at four to eight-year olds to help them learn about various medical procedures. The Rabbit Ray tool kit, in the shape of a friendly rabbit, contains an educational book and medical instruments, including a safe plastic 'needle'. Children can draw coloured water from Rabbit Ray, give him a 'vaccination', and set up an intravenous plug.

​The process of designing and developing Rabbit Ray took four years and 30 different prototypes. To help fund Rabbit Ray's development, Joytingle undertook several educational projects at hospitals, including creating videos teaching children about head wounds and stitching. Esther also went for four years without a regular salary, to keep business overheads low. Their dedication paid off when Rabbit Ray was launched in December 2015.
