What Our Clients say

Ministop Co., Ltd.
Manager of the Store Systems Department, Hiroshi Nemoto

“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.”

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.

Yper Inc.
CTO Shimazoe

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.
