Yohan Limerta is a co-founder and CTO of Cakap. In 2009 he met Tomy Yunus at the Beijing Chinese Language and Culture Center. Yunus had arrived in Beijing unable to speak Mandarin.
In 2014 the two founded Squline to teach Mandarin online. In 2019 they renamed it Cakap and widened it to English and other languages, with live online tutors.
At the end of 2020 Cakap raised a $3 million Series A+ from Heritas Venture Fund. In December 2021 it raised a $10 million Series B from Centauri Fund, managed by MDI Ventures and KB Investment, with Heritas Capital. Demand grew with pandemic remote learning.
