Online tutoring service Paper recently raised $270 million in a Series D funding round. Paper says its online platform serves nearly two million students and offers unlimited, 24/7 academic support via its multilingual tutors. The company partners directly with school districts instead of families, and says this allows it to provide personalized tutoring to all students regardless of their socioeconomic status. Philip Culter, co-founder and CEO of Paper, joined Cheddar News' Closing Bell to discuss.
