Angel investors? do you have to pay back an angel investor.?

is an angel investor like getting an grant.
where can i find angel investors

No angel investors are definitely NOT grants. They will invest in you because they think they can grow their money based on a certain percentage. Angel investors are not philantropists -- they are investors.

You can treat their investment as loan or equity. If equity, be prepared to set aside 10-15 percent of your company equity to angel investors. If you accept angel investors, be prepared to give up a portion of your business.

Business 2.0 http://money.cnn.com/2006/02/28/magazine... has a very good article on angel investors, what they typically look for, what kind of investments they support, etc.

You may want to go and pitch your ideas where investors gather. Here are some places where angel investors come and those looking for funding can come and pitch their business plans. Be sure to have a strong business plan and describe what makes your business idea stand apart:
