Photomath just raised a $6 million funding round from Goodwater Capital, with Learn Capital also participating. Photomath has created a hugely successful mobile app for iOS and Android with 100 million downloads so far.

Photomath first launched at TechCrunch Disrupt London back in 2014. The company was working on text recognition technology. Photomath was just a demo app to promote that technology.
