Investors don't spend more than 3 minutes on pitch decks. They see thousands of them every year. Especially if we are talking about professional venture investors which only invest in 4 companies out of the 1,000 entrepreneurs they meet in person per year per partner at any given VC firm.
For that specific reason I would suggest keeping the pitch deck at a maximum of 15 slides. If you can do less than that even better. Have two sets of slides for this. One with more visuals when you are presenting in person and another one with more texts for email distribution and follow ups.
Moreover, make sure that you nail it on the slides covering the team, the market and its potential growth, and also the summary of the financial projections. According to several studies those 3 slides are where investors spend the most amount of time during their review.

You should be doing most of the communicating. Not your slides. Therefore, 60 slides is about 50-55 too many. You should be able to explain your idea, philosophy, execution, plan, etc, in about 10 minutes. The most you rely on your slides the poorer your delivery. That's my experience at least.
Let me give you a different answer. If your 60 slides is mostly just one images per slide, or an engaging experience that requires you to use 60 slides, GO FOR IT. I use around 30-50 slides too, but thenagain it is so that I create a fun experience. Most of the slides are funny stuff that gets my main point across while giving the investors a fun time.
If it is 60 slides of data and stuff no one is going to read, then do what everyone else is telling you to do.
Sixty slides = the kiss of death.
The purpose of your first pitch is pass the smell test and get a chance to make a more complete pitch. So 60 slides communicates that you are incapable of making a concise presentation that simply and clearly explains an overview in sufficient detail as to allow a "tell me more" or "no, thanks."
60 is around 50 too many. Have pitched many times, usually had 3 - 5 mins and even then been interrupted. What you *should* do though is have a bunch of slides tucked away down the back of the presentation that can help answer likely questions. For example, your revenue slide in the presentation might have a simple chart, but you should then have a detailed numbers one for when someone asks you to support the data in the chart.
Is 60 slides okay? No.
60 slides in 10 minutes means you're spending an average of 10 seconds per slide. That would likely make for a poor presentation. Make the content on your slides concise and avoid putting in too many fancy graphics.
I agree that 10-12 slides is ideal. Having a few additional slides for a Q&A portion is fine but again the actual pitch portion should only be 10-12 slides.
A pitch deck's purpose is to get someone interested in investing in your idea/company and get you a follow up meeting. My guess it that 99% of investors would pass simply on the fact that you had 60 slides.
It starts and ends with story. What story are you trying to tell? Agree with a lot of what's already been written. Leave behind deck should never be more than 12. Standing-in-front-of-a-room deck should be the same with a caveat: IF you're a masterful presenter and can pull off a PechaKucha-type presentation where the slides enhance the story, then that many slides may be warranted. This is a good example of a presentation that has a bunch of visual slides that are part of the performance, not the message. A very fine line of distinction though.
way to many slides...that is a slide every 10 seconds, done at an even pace, with NO questions or comments...can't do it without rushing through and losing your audience in the first 2 mins.
As a general rule of thumb for any presentation I would do 1 slide / minute not including q&a time. The earlier you are in funding rounds, the less actual concrete information you have. VCs will be judging your team and you more.
