About Us

Cheok ran a creative agency which served mainly higher education institutions in Singapore. He was also a partner in a newly founded language school, Yi Mandarin.

Guus founded yago.sg, Singapore’s #1 website for comparing language schools.

When Cheok approached Guus to take care of digital marketing for Yi Mandarin, it marked the birth of a close partnership.

Eventually, Yi Mandarin grew into Crystal Learning, a language school with top search engine rankings for learning English, Mandarin, Indonesian and Korean in Singapore.

Guus and Cheok discovered they shared many values, and could serve each other’s customers. That’s how Crystal Marketing was born. We’ve grown into a team of 5, based in Singapore, the Netherlands, Philippines and Bangladesh.
