21K School, which claims to be India's first online-only school, has raised $5 million in pre-Series A funding from upGrad Co-founder and Chairperson Ronnie Screwvala. Founded in 2020, 21K School offers Indian, American and British programmes for children aged 3 to 18 years. "The future of education is here, and it's changing the way we think about schooling," Screwvala said.
