SaaS typically has the best decks. I used to recommend looking at the Front decks. I have commentary on them. I would look a the LinkedIn s-b deck as there is a lot of commentary to get your thinking a bit more expansively.
List of decks (filter for saas): https://www.alexanderjarvis.com/resources/collections/startu... You can search by slide type (I manually indexed 10k... to update but is a lot of work1): https://www.alexanderjarvis.com/resources/collections/pitch-...
Below: Haje made a list of 100 'teardowns' of blogs. They are available as the TC premium service shut down. I indexed them here in a table you can click on: https://www.alexanderjarvis.com/pitch-deck-reviews-from-tech...
The issue is most of the decks are sht. So you might get an idea of slides, but you will come back to your narrative aka making a good deck.
When I help do decks you do from scratch and the ball ache is figuring out your narrative, business model, what to share etc.
You will look at slides and they might hurt you by distracting you as you see slides and try together rather than thinking about your business...
I made some collections from HFs, mgmt consulting, M&A to help educate.
