Plexus Ventures’ Services of particular interest to companies based outside of Japan seeking entry into or assets from the Japanese market:


Plexus Ventures will introduce your asset to potential partners in Japan, which will be identified based on factors such as marketing strength, financial resources and strategic fit. In preparation for licensing negotiations, we will develop a valuation of the compound specific to the Japanese market.  We will actively participate in the licensing negotiations on behalf of the client, and provide post-deal alliance management for a specified period following the transaction.


Plexus Ventures will search for assets of potential interest to our client, contact companies in Japan with the desired assets in order to confirm their availability, and support all aspects of the negotiations and due diligence.


Plexus Ventures will provide assistance to the client who seeks to develop a strategy to acquire strategic capabilities in the Japanese market, as well as alternative methods of achieving the client’s goals.  Based on an agreed strategy, we will support its full execution.
