What is Kactus?


The name of Kactus originated from Cactus, a very robust plant thriving in dry desert with Y shape like antibody IgG. Meanwhile, we attach special meanings to Kactus based on our values and principles to run this company:

   ● K:Key things, we are a very focused company

   ● Act:talk is cheap, we walk the walk

   ● US: we value teamwork

Our values and principles


  •    ● Our winning formula = goals + focus + learning

  •    ● We respect people in the company and take people’s development as our mission in Kactus.

  •    ● We value direct and open communication.

  •    ● We like people who are ambitious and independent, rather than being obedient. We value people with strong desire for success, self-development, and even material returns.

  •    ● We work together as a TEAM toward our common goals: we are not a family. We are here to achieve our goals, not for having fun. Don’t worry about looking good — worry about achieving your goals.

  •    ● Mistakes are part of life. But, it is unacceptable when you miss opportunities to learn from the mistakes. Problems are the fuel for improvement.

  •    ● When criticizing, try to make helpful suggestions. Understand that the ability to deal with not knowing is far more powerful than knowing.
