Edtech startup DoubtNut has raised $3.3 Mn (INR 23 Cr) in a Pre-Series A round of funding led by Sequoia\u2019s startup accelerator and incubation programme Surge. DoubtNut was one of the 17 select startups which are part of Surge's first cohort launched in April. Existing investors WaterBridge Ventures and Omidyar Network India also participated in the round. Japanese media and entertainment-focused AET Fund has joined the round as a new investor.\u00a0Prior to this round, the company has raised less than $1 Mn, but got a $1.5 Mn funding shot when it joined the Surge cohort. The startup plans to use the funds to expand its product offerings in terms of subjects, languages and classes while also expanding its team. How DoubtNut Got 30X Growth In One Year Launched in October 2017 by Tanushree Nagori and Aditya Shankar, DoubtNut is a comprehensive learning app. It features a simple vernacular user interface and uses complex AI and ML technologies to serve up answers and video lessons in response to photos of specific problems. Talking to Inc42, Tanushree Nagori shared that the company has over 3.5 Mn monthly active users. At present, over 90% of its users are from Tier 2 and Tier 3 cities. Nagori also shared that the company has grown over 30X in the last one year.\u00a0Sarbvir Singh, managing partner, WaterBridge Ventures said that DoubtNut has made a lot of progress over the last one year and they have no doubt that the best is yet to come. DoubtNut helps students (Classes 6-12 + IIT JEE) get answers to math problems quickly and easily \u2013 the student takes a picture of the problem and receives a video explaining the solution, in response to the problem. With over 100K videos in the library prepared by experts from IITs and other leading institutions, the company believes these are a valuable tool for students and can also act as an aid to teachers. \u201cTanushree and Aditya\u2019s insights came from their own experience where despite great teaching, they were not able to cater to individual doubt resolutions of students without turning to technology,\u201d said Namita Dalmia, Principal, Investments, Omidyar Network India.
