About Us

At THECOO, we're leveraging cutting-edge technology to build Fanicon, an innovative and interactive fan community platform. Launched in December 2017, Fanicon is a subscription-based, premium fan community platform where fans can engage directly with their favorite artists and personalities (“icons”), who are directly involved in content design and creation. Fanicon has experienced continuous growth since its launch. As of December 2024, Fanicon hosts over 3,500 communities and over 350,000 fans.

At THECOO, we foster a culture where engineers can fully focus on building great products. As we scale Fanicon from 10 to 100, we’re seeking someone who can leverage their expertise to help us take the platform to the next level.
