I don’t know whether they’re Unicorns, but at least we have companies like Booking.com, Adyen, you could argue Gitlab has Dutch roots, and smaller ones such as MessageBird, WeTransfer, Usabilla, etc. These are more well known names, but there are plenty and plenty of smaller ones, where “small” can still be around a hundred employees.
Again, I’m not claiming that our startup climate is anything like what your see in SV, but it’s definitely a fairly healthy scene, and it would be an insult to characterize these as grant chasers.
