I do agree to some degree with that (I'm the OP not the siblings :)). We just have to define what small means. Netflix or Google are way up there in scale. In relation to them we are small. We also don't actually have microservices vs. what I'm reading about Netflix's architecture. We probably have "macroservices" in comparison with them but we definitely aren't one monolith. We got a bunch of "small monoliths" so to speak.
That said, we're not small either. In our niche, which you might recognize if I said more, we're the top solution customers choose (but I won't go into much more detail than that for obvious reasons).
