About Us

Who We Are

J.H. Whitney Data Services (JHWDS) specializes in providing analysis of the global economic domain to enable its clients to address geostrategic risk challenges. The JHWDS team includes experienced financial, legal, and former US Government (USG) intelligence professionals who provide data-driven insights by applying their experience and expertise in global macroeconomics, public policy, and capital markets. These insights enable the continuous assessment of nation-state competition and other geopolitical factors affecting security, supply chains, and other business operations. Key members of our team bring a unique combination of experience from leading financial institutions, as well as experience in private equity/venture capital and USG entities.



As increasingly incongruent political, economic, and national security objectives drive reduced economic co-dependency between nation-states, countries and companies will require alternative tools that enable them to navigate a new global economic order.

Digital Transformation

Adoption of Industry 4.0, which drives continuous advancement in industrial activity, will require the development and leveraging of new technologies such as Cloud computing, 5G, the Internet of Things, artificial intelligence, and autonomous systems.


The gradual global shift away from fossil fuel combustion toward renewable energy will require the transformation of supply chains, manufacturing, and production to meet net-zero targets.

Emerging Technologies

Emerging technologies include AI, biotechnology, cyber, and microelectronics, among others. Such technologies are critical to all areas of scientific advancement, industrial innovation, economic competition, and national security.
