What software do you use to create great looking pitch decks?

Niftio is actually a tool for presentations, so they have a lot of templates and some pitch deck templates.

You might be thinking that this isn't quite what you were looking for but Keynote is incredible. A pitch deck should be simple and to the point. My most recent pitch was made using keynote and we kept everything to a minimum. Black text on a white background with each slide only having a title (and a subtitle on one slide). Play around and don't be afraid to ask around either on what looks good. I personally have always found the clean and simple slides most affective as that directs attention to you, the speaker. People invest not in ideas but in the people behind the ideas.

This is an unconventional way to do this, but it is quite efficient and direct in communicating the point across. Check the medium post around this: https://medium.com/swlh/open-let... You can make your own pitch bot at: https://admin.hellotars.com/ Full Disclosure: I am the maker of this Product.

Sketch is great because it is a lot faster to use than Adobe Illustrator for most things and is fairly powerful. Plus, you can just copy and paste into Keynote or Powerpoint. It's not perfect, but it satisfies my desire for more power than either of those two products.

This might sound old school, but even with advancements in Sketch and Keynote, InDesign really is the best tool for typography and refined layouts. It's made for publishing so it's super easy to set up grids, master templates, set type and character styles, baseline grids etc. However, it's not as advanced with video embeds or motion. So I'll often layout all of my decks in InDesign and then export PDFs, drop them into Keynote and add animations, prototypes etc. Other layout tools aren't advanced enough for the level of finesse I'm looking for on the type and layout side of things.
