Neil Craig, who chairs Enterprise Angels, said that most angel groups worldwide had sidecar funds.
"A lot of people want to enter the space, who qualify as wealthy and or experienced, but don't really have the confidence to make individual decisions on these types of investments."
"The sidecar fund gives them a leg up in building a diversified portfolio.
"And it gives the angel group more firepower in terms of funding investments, particularly local ones, so we can bulk up and make a meaningful contribution to an investee company's equity."
Mr Murphy said the fund would give outside investors all of the advantages of the angel group members.
And as managers, the Enterprise Angels board had access to the members, many of whom had a real depth of experience in specific sectors.
"Those outside of Enterprise Angels will be able to benefit from that level of expertise and experience in making investment decisions," he said.
