NoRedInk

NoRedInk (stylised as noredink) is an online web-based writing education platform.

History
NoRedInk was founded by Jeff Scheur, a high school English teacher at Whitney Young Magnet High School in Chicago. After documenting years of misconceptions that popped up in his students' writing and developing a taxonomy to address them over several years, Scheur posted an advertisement on Craigslist asking for an engineer to help him build an educational platform. Scheur's students voted on the name "NoRedInk."

In February 2012, Scheur shared the first version of NoRedInk with some colleagues at an Illinois conference. The application grew to 15,000 users in its first two months. In September 2012, NoRedInk won the Citi Innovation Challenge, hosted by NBC, netting the company $75,000 in prize money. In January 2013, NoRedInk raised $2 million from a series of investors, including Google Ventures.

In 2021, NoRedInk raised a $50 million, series B.
