Global Uni rankings have a big bias toward research. What the poster is saying is that Germans do more of their research at these institutes than at their Universities so German Universities rate poorly on global lists.
As you can see, in Germany and France, research institutes take the place of what in the US and the UK would be universities like Harvard, MIT, Oxford, and Cambridge. Fraunhofer doesn't even show up, because while they do a lot of amazing stuff, they aren't under publish-or-perish constraints (they instead have contracts to fulfill) and so they publish comparatively little.
This has a number of reasons, some of which are pragmatic. For example, if a French or German university wants to hire a professor, that professor usually has to be able to speak French or German, respectively, at least at a near-native level to be an effective teacher (there are exceptions, but it's still a frequent requirement). Research institutes aren't constrained in this fashion, even though they closely interoperate with universities.
Great looking site, really catches your attention.
My input from a "currently evaluating different controllers" perspective is that the page somewhat lack information about interfaces, possibility for expansion (in our case we have requirements on interfaces not commonly existing out of the box).
I also believe that of your target audience is industrial solutions skip the "BS" (i.e. "Our controller allows you to develop voice controlled devices that are truly beneficial in the real world.") and instead go for specs. Even though your controller is not ready for the world i guess you have a goal or conceptual model?
Looking forward to see where you end up, I signed up for the newsletter :)
