It's interesting that the 6-slide pitch deck doesn't have a "team" slide. Maybe was it used in the idea phase?
PS: Thank you. I was looking for something like this.
In practice I use the 6-slide as a first step, akin to a simple sketch, suitable mostly for internal discussion. Then I work with the founders to expand the 6-slide deck into the 12-slide, which gets sent to external people. The 12-slide pitch deck can take a week or so for the first few drafts.
