I would say, it depends on the orientation of your business. If you're targeting cosumers, they may have more time on their hands during the holidays to go play with your service.

If it's targeted towards business, forget it, now is a terrible time to launch. For the same reason, people in business have their head elsewhere, either closing the year, dealing with the retail high season, or going on vacation.

The exception to this would be if your offering is b2b and has to do with a category that is very well allocated to an expenditure item in a budget for which there is generally speaking potential 'use it or lose it' money.

As the saying goes: "Launch as early as possible, but no earlier."

Completely depends on your market and who your targeting. All the movies come out during the holidays and during the summer. The latest trapper keeper comes out in August. I think your question is one only your team can answer themselves.
