7. Complicated deal terms: While planning for an investment, keep it simple. Sometimes angel investors will push for complex deals which will give them unusual rights. This is bad for your company as it can haunt back your company in future. And also, future investors will be reluctant to invest because the earlier investor has veto rights. So you should negotiate for a fair deal keeping it in-line with the industry standards.

8. Trying to raise money just for the short term: Many entrepreneurs try to raise money to cover expenses for a period of time which is usually 12 to 24 months, reflecting their short-time thinking. Instead, they should concentrate on raising funds to reach a milestone like signing a big deal or reaching a million downloads of your software. Also, raising a bit more money than you'll need is better than too little. And during the presentation, let the valuation of your company come up naturally instead of putting front your own estimated valuation.
