as a german CS-Student it's always interesting to see german companies pop up (i have to work somewhere when this is finished). Nearly every time the stereotype is right. They are always building "pro oriented" specialised physical things, now lenses, a few days ago i stumbled across another one that builds really high performing magnets (i think, not into machine engineering) and is located not far away from where i was born. But i have jet to see the next promising Tinder/Slack/Social-Whatever from Germany. Everything is somehow related to machinery.
