Note that OP didn’t say anything about “close to no developers”, only that they could tell they had become more productive.

I too know I am being more productive. The most concrete examples for my work has come from the ease of prototyping: making a quick quasi-working version of an idea is now insanely easy, so we’ve been able to explore (and adopt) ideas that would not have been worth the effort previously.
