Hi there,
I have a feeling that you're asking because you'd like to learn how to create good decks. As such, I've provided an explanation further down. However, if you're looking for actual decks, take a look here:

I recommend that you start to approach pitch decks in this way: boil down good vs bad design into principles, determine the key things to check in a slide, identify what small tweak changes a slide from looking average to awesome. Do this by 1) Getting people to review your slides and note the specific changes thy make and 2) Seeing good slides and asking the person how they did that.
For example:
- Always align items on your slide
- Look to keep even spacing and sizing between multiple items (i.e. if I have 4 icons down the left column, I make them the exact same size, and set them all to be equidistant from each other)
- Use colors to highlight focus areas and draw the eye - but don't overuse colors! (Maybe my first column will be dark blue with white text, if it's asking the key questions we have. Or maybe if I have a "summary" or 3 takeaways on a slide I'll bold + add color to the specific words/phreases that each takeaway is really addressing)
- Identify what you are trying to achieve from the slide and then pick your template - there are probably 5 template I cycle through based on what I need. Coloring + content make them look different from each other, but boiled down, they're all quite simple (i.e. a table slide, a sequence slide, a 3 key takeaways slide, etc. etc.)
The list goes on, but I hope this starts to give you an idea of actionable steps you can take to make your slides better.
