You need a business angel if you need some money to invest in your business and if you think you could do with a mentor. Generally Business Angels will not invest in your company if they believe the company has no future and is a bad idea. If however they think your business is an innovative idea and has great marketing potential and selling ability then your are on to a good start. If you have an already established business and are looking to expand over seas for instance then a business angel might be just what you are looking for. They can come up with the finance for your and help with the expansion. Business start ups are also another area where business angels can help.
