Remember the tutions we used to go when we were in school? They sell the idea that if you enroll your kid he/she will score very well. So parents give it a try, spend money upfront and the kid end up getting ok-ish score. Indian parents are never satisfied so they change tution.
Imagine the same scenario, but the tution is virtual. Parents give it a try and pay hefty fee upfront. But end up realising its basically an expensive version of Youtube premium. So they drop.
They need long term customers to sustain. Which I don't think is possible atleast in India.
