And, not sure if you meant it this way, but I wouldn't say business plans and slide decks are something I'm bad at. I actually prefer business over CS, but figured CS was a more worthwhile degree to pursue. I know in general CS majors are probably viewed as just coders that lack business acumen, but there are always exceptions! =]
And yes, thinking about it some more, I agree a slide deck is probably overkill to this type of meeting. Writing the business plan has allowed me to really know my idea in depth, so hopefully this will come through in conversation. Thanks again.
Since the VC has a strong technical background (M.S. in CS), I would guess that they would probably be more interested in the course of a conversation in the "intellectual" / technical side of things rather than the mundane financial boring stuff.
Also, probably better than seed funding would be to connect with this VC, and see if you would like him to mentor you. If you're throwing a business plan and slide deck out it might seem like you are just another opportunistic gold-digger, whereas if you can just show how passionate and energetic you are, as pg suggested, its much more likely to lead to a longer term relationship.
