Instasolv, a Noida-based edtech startup, has raised $2 million in pre-Series A funding from undisclosed investors. The company is a doubt-solving app for students from Class 6 to 12 in subjects of science and mathematics and also IITJEE and NEET. According to the startup, the fresh funding will be used to expand the question and answer base to state level curriculum in different languages. It also plans to develop more features so that students can take tuition and coaching on the app itself.
