Yes, you can use Pepicon to raise just a proportion of the total amount of funds you are raising. 

In case you are currently in the middle of raising growth capital or in case you for example already secured some investors through other ways, you can simply launch a funding round with Pepicon for the remainder of the total amount.

You can fill in all the relevant details in the Funding target section when launching a funding round and then clarify its only a proportion of total funds (possibly mentioning who and how many was raised already out of Pepicon) in the Investment Memorandum, in “The New Issue” section.
