Meet the minds behind Cinter Technology


To deliver high-quality local and global technology solutions that meet our clients’ specific needs and goals.

Our cross-cultural position empowers us to draw on a deep pool of bilingual talent: English, Japanese, Korean, Chinese, and Vietnamese.

Since then, we’ve grown to 9 locations, from New York, California, adding Yokohama, Japan in 2021. Today, Cinter Technology supports our customers with custom information technology solutions that help them grow their business.

It has been a great pleasure working with the staff from Cinter Technology Services since March 2020.

We did not have any IT specialists and resources to deal with our computer systems network and Information Technology needs. The staff from Cinter takes care of all of the computing and technology needs for our company.

In addition, some problems have been resolved within a few minutes. Cinter gives us the peace of mind to stop worrying about our system.

We really appreciate their job.
