Q: Along with BaeMin and SmartStudy, Buzzvil is spotlighted as a startup company with an amazing culture. How amazing is it specifically?

The core of our culture is horizontal work environment. We believe that our employee’s growth is directly related to the company’s growth, so we strongly encourage each individual member’s personal improvement.

For example, I would like to introduce the flexible work environment here at Buzzvil. Employees are free to arrive at work at any time between 9am and 10am. Location of work is up to each member as well. We got rid of the Korean appellation system which was rather authoritative. Instead, we use English names, which allows conversations without too much formality. We also have a special CEO talk, which allows our employees to ask questions anonymously to the leaders.

In addition, Buzzvil thinks that employee development leads to company’s development. We try our best to encourage each employee’s personal improvement. For example, we support tuitions for academic programs such as foreign languages programs or coding programs. Employees can buy unlimited amounts of books for free as long as they are self-improvement books.

Employee Satisfaction is another key factor that Buzzvil values. We provide breakfasts every morning. If employees have to work late, we cover costs for their dinner as well. There is unlimited amounts of refreshments and drinks at the office. We fund club societies inside the company which includes the soccer club, cooking club, and the coffee society.

Buzzvil truly believes that employee’s satisfaction and forming positive atmosphere leads to better results.


Q: Could you tell us about future direction of Buzzvil?

Currently, Buzzvil is the biggest lockscreen advertising network in the country. We aim to become the largest in the world. We want to expand up to 80% of the world’s lockscreens, and provide free mobile experiences through lockscreen.
