DEFTA Partners is a leading venture capital firm focusing on innovative technologies in IT and healthcare.

Healthcare Focus

Today, DEFTA Partners foresees new opportunities in the integration of technologies in the IT, biotechnology, pharmaceutical, and other healthcare fields. With a goal to extend people’s healthspan, we are investing in companies developing advanced therapeutics, health IT, and enabling technologies.

IT Focus

In the late 1990s, DEFTA Partners predicted that the fundamental structure of information technology would shift from a computation-centric model to what we call the pervasive ubiquitous communications (PUC) model. Our PUC vision has paved the way for successes of technology companies in fields like embedded devices, digital TV, and online security.

Global Focus

Since the 1980s, DEFTA Partners has invested in more than 100 companies in the U.S., U.K., Israel, Bangladesh, and Japan. We bring hands-on global expertise to our portfolio companies, enabling them to scale up internationally. Sustainable growth in the developing world is also our goal. In Bangladesh, for example, we work with BRAC, the world’s largest NGO, in establishing and operating a joint venture bracNet, an internet service provider.

Working with DEFTA Partners

1World Online is working with DEFTA Partners for almost 3 years, and we recognize George Hara & his team as one of the most valuable investors and advisors. DEFTA is very instrumental and truly helpful during both exciting and difficult times and provides support in all aspects, by continuing to participate across all rounds, introducing 1World to very valuable business prospects such as the Japanese government, regularly reviewing our progress and advising on tactical and strategic matters, and even helping with product development (e.g., localization when we added the Japanese language).

Kyoko Watanabe is on 1World Board of Directors, and she is a tremendous person to work with: knowledgeable, experienced, very delicate in providing recommendations but also very keen in making sure we don't lose opportunities.

Overall, DEFTA Partners is an ideal investor (and a friend) to work with, and we are looking forward to providing back what is expected: a solid return on their investment and trust!
