There are lots of people obsessing about feeling threatened in what they do by all this. It's an understandable response but not necessarily a productive attitude. It's really just an opportunity to reconsider what it is you do exactly and become better and more efficient at that. Perhaps if you spend most of your time trying to produce slides, designs, etc., freeing up some of that time for more high value activities is not such a bad thing and something that you should have been striving to do anyway. In our case, using our refined pitch to drive sales is what we should be doing. Spending time to refine the pitch is a necessary evil and not the main thing we should do or even want to do. So, this is an enabler not a threat for us.
I'm actually a CTO; so me spending time on sales pitches is not the most obvious use of my time. But in a small startup, if something needs doing, I probably need to be involved. So, anything that makes that more efficient is more than welcome.
