We operate a serverless infrastructure (lambda + dynamodb) at secapps.com with a super small team, and we could not be any happier. Mind you, currently, we have over 30 services (not microservices but products we sell to clients) and well over 30 applications.
While you should take my comment with a grain of salt, for me it is a live testament that the serverless development paradigm works.
That being said, I also believe that it depends on how exactly you work and develop products/features. That is probably more important than the technological approach used. We have some very strict mental model about lambda which do not quite fit the mental model used for microservices.
