> It’s also not expected to make any real enterprise sales during Q4 or the beginning of Q1
I've worked at a few enterprise software companies in the US, and Q4 is always the busiest time for sales. Having a deal roll into Q1 is very undesirable, so sales people do what they can do close before the end of the year. Q1 is incredibly quiet.
On the Engineering side, yes - Q4 and Q1 are super quiet as sales is driving the economic machine in Q4, and everyone's doing planning in Q1.
