Our Team


Dr. Shan Nair

Dr. Shan Nair is an entrepreneur and consultant on international expansion. He was the first to spot and develop the niche market of International Expansion Services (IES) which was previously fragmented. In the process he has worked with many companies in their early stages who have since become household names such as Tesla Motors, FaceTime and Sonus Networks. His role is to promote the services offered by Nucleus and to work with the management team to ensure a high level of technical excellence and client care is maintained at all times.

Nucleus is unique in that it provides true one stop, multi-disciplinary, multi-country shopping for companies seeking international expansion or with international operations. A single experienced Client Services Director and an Accounting Manager will be your sole points of contact for all of your foreign consulting needs – you will not need to chase multiple accountants, lawyers and HR consultants in different geographies or have a single contact point with little expertise acting simply as a postbox. The Client Services team is backed by staff at senior and mid-management level each having more than a decade of experience in providing IES services.

Shan has a doctorate in nuclear physics from the University of Oxford. He has received multiple recognitions for his contribution to business in the US, UK and India.
