Our Commitment

"As a business we are committed to bringing leading-edge technologies to the market. Whether that is based on efficiency, cost-savings, or flexibility, we are continually striving to innovate so our customers will benefit.

We understand that our employees are what will move this organization forward. We are committed to creating a work environment that will allow our employees to flourish and succeed while still experiencing balance in their lives.

We are also committed to serving the communities with which we are connected. This means that our corporation and employees dedicate time giving back to and serving those who are most in need. Through our manufacture's rep giving program, we also ensure our outside partners have a chance to make a difference in the communities that they call home.

Finally, and most importantly, we are committed to our customers. We do all we can to service the customer as though they are part of the CUI family. We look to create long-term partnerships, not just short-term transactional relationships. We realize that our customers are what drive our business, so we do everything in our power to see our partners' success through to fruition."

- Matt McKenzie, President of CUI

Core Values


CUI Inc was founded in Beaverton, Oregon in 1989 as a joint venture with a Japanese electronics firm. Over the past three decades, CUI has grown to become a recognized name in electronic components worldwide in the areas of power, interconnect, motion control, and acoustic technologies. In an effort to expand our global footprint, international offices have been added in China, and most recently, in Japan to provide expanded design, manufacturing, and sales support services to our customers.

In 2008, CUI Inc was purchased and incorporated as a wholly owned subsidiary of Waytronx, Inc., a platform company dedicated to the acquisition, development, and commercialization of new, innovative technologies. In January of 2011, Waytronx changed its name to CUI Global, Inc. (NASDAQ: CUI), better reflecting the company’s strategic direction into advanced electronics targeting various markets and industries.

The merge with a public corporation has offered CUI access to new sources of capital, allowing for a more aggressive move toward acquiring new technologies and building our operational resources. We now look to move into a leadership position within the industry by integrating a growing patent portfolio of innovative technologies into our established and successful electro-mechanical product groups.
