Goldman Sachs Group Inc. unit Petershill is nearing a deal to buy an undisclosed stake in venture capital firm General Catalyst Partners LLC, Bloomberg News reported, citing unnamed sources.

One source said the potential stake buy would be the buyout fund's first investment in a venture capital firm and would be one of the first venture capital stake transactions by any firm focused on partial acquisitions of alternative asset managers.

Terms are still being discussed and the negotiations could end without a deal, said the sources.

A representative for the global investment bank did not comment on the matter, while a representative for the venture capital firm did not respond immediately, according to Bloomberg.
