A 'fund pitch' differs from an 'equity pitch' on BnkToTheFuture in a few ways.  With a fund pitch BnkToTheFuture has already purchased an allocation of equity in the company that is already held in a structure similar to a fund. There is a fee to invest which is added on top of your investment and will be displayed to you at point of investment. This differs from an equity pitch where there is no fee. 

In summary:

The amount invested in the company has already been transacted to the company and we are making exposure to that company available to investors with a fee. With an equity pitch there is no up-front fee to invest.
