Big, Bold Designer PowerPoint Templates for Your Next Pitch

These are all nice, but I think the #1 important thing to take away is to focus on big ideas and high-level concepts and communicate them clearly. If the slides confuse the viewer or distract them with overly chic typography, they can't be considered successful.

Ultimately, you have to drill down and ask yourself how you can distill the essence of what you want to pitch into a very brief yet powerful slide. Hopefully these slides can help some to do that!

wonder if there are similar templates for LibreOffice ?

I wouldnt mind paying for something like that
