Yes, You should get a Schengen visa and it can be applied through the Embassies of any of the countries coming under this group. You may approach either German Embassy or French Embassy. They require an invitation from any of the German or French companies and when the visa is stamped on your passport then you can go to any of those countries. There will be single or multiple entry visas. I used to get Schengen visa to France and the Principal Companies in France used send me an invitation to attend some meetings there.
