Our Clients Say About Us

"Our company has a variety of development projects that require accuracy and speed, and we have taken notice of offshore development as a way to achieve these goals. Utilizing offshore vendors can provide cost and speed benefits compared to working with vendors in Japan. If the offshore vendor has excellent communication skills, these benefits can be fully realized.
As part of our search for a suitable offshore vendor, we considered multiple companies and ultimately chose Kaopiz based on their strong reputation as an excellent company. Since engaging them, they have implemented agile development to respond to demands such as testing during core systems replacement. We appreciate their contributions so far and look forward to continuing to work together for the benefit of our company."

Hiroshi Nemoto

Manager

"Our company is a comprehensive education firm that places great emphasis on the integration of education and IT. In order to meet our diverse development needs, we have chosen to utilize offshore development services. Kaopiz has proven to be a strong partner, not only for their ability to attract top talent but also for their sincere approach and consistently high-quality output. We have established a solid relationship of trust through the flexible and responsive support of their bridge SEs who work with us on site and adapt quickly to changing project specifications."

Koichi Nakano

IT Business Unit Manager

"Our company has been conducting offshore development in Vietnam with multiple partners since 2007. Among these partners, Kaopiz stands out for its abundance of knowledgeable and experienced personnel who prioritize thorough team-wide information sharing to maximize organizational strength. Their innovative research and application of unfamiliar services and technologies allows them to solve difficult requirements and enables us to entrust them with our work with complete confidence in their technical capabilities. Despite the inevitable language barriers that come with working across different countries, Kaopiz provides detailed information sharing which completely eliminates any concerns regarding communication. As a result, they have become an indispensable partner regardless of project size, providing trusted collaboration and exceptional service to our company."

Ogura

CEO

"I was concerned about offshore development for the first time. However, the executives and business analysts displayed excellent communication skills, allowing us to proceed with the project quickly. Despite using technology that Kaopiz had no prior experience with, they were flexible in their approach, resulting in a successful release. During the final stages of the project, I worked alongside the team in Vietnam and was impressed by the company’s vibrant and positive culture."

Shimazoe

CTO

"As technology drives our company to focus on speed, Kaopiz has shown its unique capability of quickly adopting new technologies and creating applications in a short time without sacrificing quality.
Kaopiz offers high-skilled engineers who can communicate in multi-languages. They are extremely flexible, responsive to changes, directly supported from managers who understand the nature of a startup company. These make our collaboration with Kaopiz very pleasant."

Ryan Hsu

Project Leader

"There are many providers of dedicated team model development, and after considering several companies, we have chosen to partner with Kaopiz. This decision was based on Kaopiz’s exceptional capability to recruit skilled professionals from the founders’ university, effective communication skills, and dependable service. Most importantly, being able to directly communicate with the founders enabled us to be flexible in various aspects, which was the biggest factor in our decision.
