This is me. I‘m Kru Chai. I’m CEO || Science Teacher || Writer || Consultant || Digital Marketer || Speaker

Hey! My name is Chaiyapon Chawanwanitchai (ชัยพนธ์ ชวาลวณิชชัย), or you can call me ‘Kru Chai’ as my first job was a science tutor for students in primary schools. My passion in teaching led me to my success in operating my first business, Big Brain Academy, since I was 19. At that time, I was studying Aviation Management at Kasetsart University (KU68). Then, I started my second business called ‘Skytouch Academy Thailand’ in 2014. Currently, I’m the president of Mind English Language Academy, an English institution specially for adults who want to improve their speaking skills. Now we have 25 branches around Bangkok, Chonburi, and Chiangmai. I’ve been passionate with sharing, so, I’m also a public speaker. Nice to meet you all!

Content Marketing

Content is always the KING!, forever and ever.


Knowing others is intelligence; knowing yourself is true wisdom. Mastering others is strength; mastering yourself is true power.

Professional Public Speaker

You can speak well if your tongue can deliver the message of your heart.


It’s like everyone tells a story about themselves inside their own head. Always. All the time. That story makes you what you are. We build ourselves out of that story


Education is the key to success in life, and teachers make a lasting impact in the lives of their students.
