From my experience, defintely yes. I use the Revel framework for creating my APIs to be consumed client side (Angular).
When I make changes, refreshing the browser results in a re-compile which takes less than a second (assuming I have modified several files) on my 2012 Macbook pro.
With Go, unit testing is also blazing fast. My entire test suite (around 30+ tests) takes around 0.2 seconds.
Just for comparision, I used Play 2 (Scala) for a short while before that. Re-compilation would take in the region of 10 seconds. Startup costs are high in the Java/.NET world :(
