Xandex Ventures

Xandex Ventures is the wholly owned investment arm of Xandex Inc., legally organized as Xandex Investments LLC. Like most San Francisco Bay Area tech companies, Xandex Ventures was founded by entrepreneurs. Over the decades of doing business globally, we have striven to be innovative, entrepreneurial, progressive, and ethical in all of our business endeavors. We hope to spread these values as wide and as far as we can with the help of entrepreneurs. Our goal is to fund, support and nurture dynamic, bright and dedicated individuals and teams with a clear vision, and great aspiration to realize that vision through hard work, ingenuity and team spirit.

Xandex Ventures is a venture capital investor in emerging fields which we believe improve commerce and promote the well-being of individuals. Specifically we are seeking investment opportunities in mobile digital technology deployment for commerce, entertainment and digital health care; healthy lifestyles and eco-friendly products, and medical devices. Some past investments (and current portfolio companies) include ventures in Bio-Pharma and Renewables, however, we no longer participate in these investment classes.

Kubi Telepresence Robot

The newest addition to Xandex product lines is Kubi. The Kubi Telepresence Robot is an interactive remote controlled robot that is designed to hold an Apple or Android tablet during live video meetings. Kubi is Japanese for "neck" and Kubi lives up to the name by providing 300 degrees of pan and 90 degrees of tilt movement, allowing a remote user to change viewpoints using simple App based or browser based controls. Kubi enables video meeting attendees to look around the room and truely engage and connect with other attendees in a way not possible before.

In 2015, Xandex Ventures made a significant investment in Revolve Robotics, a San Francisco startup that had developed the Kubi® Telepresence Robot. Kubi is a remote controlled motorized stand designed to hold a tablet computer in order to provide a more engaging and effective video conferencing experience to remote video conference attendees. Xandex completed the acquisition of Revolve Robotics assets and intellectual property in January, 2019. The Kubi team at Xandex built a new online home and store for Kubi at www.kubiconnect.com and implemented new product and software improvements to enhance performance and expand Kubi features.

Working at Xandex

Our vision of being the preferred supplier of innovative technology solutions worldwide requires us to seek out creative solutions in our product design and manufacturing processes as well as our management practices. You will find a spirit of innovation and continuous improvement at the root of everything at Xandex. In our effort to be THE preferred supplier, we seek to exceed our customers' expectations while living by our guiding principles.

Guiding Principles

The guiding principles listed below are the core values that shape our corporate culture.

Xandex practices an "open door" management style that encourages the flow of communication through all levels of the organization. Company meetings are held quarterly so that every employee is well informed of our annual and quarterly goals and progress. Both formal and informal means are available to all employees in the organization for providing input on improving our processes and practices.
Xandex has built its reputation on developing and offering new and creative test solutions. By investigating and investing in the latest developments in electronics, materials science, business practices and computer/software technology, Xandex continues to be a leader in the development of next generation test solutions.
In 1997, Xandex was among the very few small companies who earned certification in ISO 9001 quality standards. In 2003, Xandex was re-certified in the revised ISO 9001:2000 standard. In 2010, Xandex was re-certified to the latest ISO 9001-2008 standard. At our company, Quality is not just the function of the Quality Department. It is ingrained in every aspect of our organization and is the responsibility of each and every employee.
A spirit of cooperation exists at Xandex. It is evident not only in our internal activities, but also in how we interact with our customers and suppliers. Internally, cross-functional teams are the core of our manufacturing, product development and process improvement activities. Externally, we partner with our customers and suppliers in finding unique and cost effective designs and test solutions.
In the competitive and volatile climate of any high tech industry, agility and accuracy (getting it right the first time) are necessities. Our managers are routinely challenged to raise the bar for themselves as well as for their staff. We believe that continuous improvement of individuals in our team benefits the entire organization. We often provide opportunities for advancement and promotions from within, as well as encourage personal and professional development by offering financial and educational assistance to all employees. Our commitment to providing a safe and healthy work environment is demonstrated by our progressive ergonomics program, which has been recognized in safety magazines. We have CPR and First Aid trained Safety Teams who drive our safety practices, which include quarterly site inspections, emergency practice drills, and ergonomics workstation evaluations. Our work environment and safety practices far exceed OSHA standards.
Since the time when Xandex was a small company, we have tried to provide competitive benefits and compensation for our employees. Our salary structure is founded on comparisons with High Technology Surveys, which represent much larger companies (in revenue and employee level). Our benefits, like fully vested 401K, are considered quite generous for the size of our company. We have shared our profits, our savings from process and safety (workers' compensation cost) improvements, and have always matched or offered better annual merit adjustments than national averages. Being a private, family-run business, we give extra care and consideration in looking out for the financial well being of our employees.
We believe that integrity is key in building relationships. Our management practices and policies consistently promote fair and ethical conduct. Xandex has always been highly diverse and passionate about its zero tolerance policy towards ANY form of harassment. Our policy and value system applies not only to our employees, but also extends to our customer and supplier interactions.
Xandex supports many non-profit and charitable organizations in our local community. We encourage participation in volunteer programs such as mentoring in our local schools, or adopt-a-school to promote math and science studies. Our ongoing donations to Sonoma State University, Petaluma Fire Fighters, The Salvation Army, Petaluma People Services, Women's Justice Center and many others are highly appreciated.
