No one likes risk. Even early stage investors. A good investor deck should convince the investor that whatever risks are associated with particular investment opportunity are seemingly mitigated.

Team - not your first rodeo, know how to win, subject matter experts. Focus - clearly stated value proposition. Dream - big market, big value. Plan of Attack - clear path to capture market share. Validation/ Traction - customers! Tech - solid, non-obvious, not easily replicable. (i.e. if your successful, someone else can't just hop into the market and eat your lunch). Use of proceeds - not just pay my salary, but grow this business. Next big milestone: profitability? another fund raise?

If you hit on these, then investors will want to put money in their favorite types of companies: the one's that don't look like they need it. ;)
