Want to look at a few high profile examples?
* Chris Dixon: needs no intro, coded many lines of code at and before hunch.
* Conway: a salesman in the past, you take this one (although he's seen more startups than you've written LOC)
* Hoffman: has written many LOC
* Thiel: yup
* Andreessen: I've seen it first-hand
* Bezos: yup
* Sacca: business guy, no LOC
* Paul Graham: you're using his LOC to drive traffic to your site
The list goes on. Fact is there are angel investors and VCs that have not written software, but since when does that truly actually matter when they're giving you advice on how to run a business, namely finding out what people want and give it to them? Your comment in this very thread about banning speakers who use office for their slides (who cares?) tells me of your naivety, but here's a final tip: be formulaic all you want, but talk about things you know for a fact.
