If I can look at a deck, then I can do two things that I can't do during a pitch. First, I can close my eyes and take a deep breath for a minute without missing anything. And second, I can see right away that, for example, this company is in a sector that I am not focused on (because I don't know anything about it) and so I am not going to invest in it even if it looks like a great opportunity. I am an individual investor with a very narrow focus (I look for companies in particular technical niches) so I can eliminate 80-90% of opportunities just by knowing the market segment they're in. A company might be well positioned to revolutionize (say) fashion design, but I'm not going to invest in it because I know absolutely nothing about fashion design, and I don't invest in things I don't understand. With a deck I can figure this out an order of magnitude faster than if I have to sit through a whole pitch.
I just sent u an email. Any feedback appreciated
Two suggestions:
1. Post this as an ASK HN so that you can get feedback from people who are a better fit for this sector
2. Just build the damn thing. How hard can it be? (And if the answer is "really hard", then your deck should explain why, and why you are uniquely qualified to do it.)
