Where talent meets passion.

Our Core Values

Our Core Values shape our culture and guide everything we do.


We inspire each other.

Without the goals, passions, and dedication of our team members, we would not be at where we are now. At TECO, we inspire each other to grow. 

With us,
do what you love. 

No idea is impossible when you're with us. We always seek creativity and innovation to fuel us forward. 

At TECO, do what you love, not what you're given. 

With us,
don't be held back. 

There's no finish line at TECO. As we accomplish our goals and visions, we are constantly looking to improve and grow. 

With TECO, don't be held back. Look forward! 

"Being able to work with inspirational people everyday is really exciting. At TECO, while everyone is part of their respective departments, I appreciate that our opinions and ideas are respected across the company. Also, the fact that you're able to kick off projects that you want to pursue right away makes TECO a valuable place for those wanting to grow and challenge themselves."

We're like a sports team.

TECO feels like a sports team. We practice together, experience failures and victories together, and hold each other to our collective standard of excellence.

With us,
live for change. 

TECO's roots start in education, a sector highly resistant to change. ​ With our goals to reimagine the future, we're always looking ahead of the curve. 


​At TECO, we live for change, and our culture reflects a desire to be a driving force for what's better.

With us,
dream big. 

Our mission to build prepared students, confident leaders, and successful citizens is broad, vast, and optimistic.


Working towards such a big goal is not without its difficulties, but with our team by our side, nothing is impossible.

"TECO is a place where people can really maximize their potential. Our PO (Product Owner) structure particularly gives people ownership over projects that they get to work on from scratch - with the help of our team. While maximizing responsibility, our meetings are also fun and filled with laughter that make TECO an exciting place to work at."
Sangho Yoon | Chief Product Officer
