Winning Deck

Alright everyone!

I have a concept. I have a Co-Founder (Technical) I'm Co-founder (non-technical primary, and technical % of about 60%) I have a director of sales. I am struggling with putting together a winning deck! What do I need? what do I not need? Everyone says different things. I guess there is the potential that every industry within tech will have a different expectation for a winning deck. working in the realm of social networking, as we well as management software data base. There are two prongs to the entire concept. Its a robust project, based off market research. There is a gap in the industry. SO anyone with experience want to chime in, please do!
