John Coyle, the global head of JPMorgan Chase & Co's financial sponsor group, has joined Permira.
Coyle will be co-head of the Europe-based firm's New York office together with Tom Lister.
"We are thrilled to bring a person of John's calibre to Permira and simultaneously strengthen and deepen the Permira team in North America," Lister said in a statement.
A JPMorgan spokeswoman declined to comment.
In an earlier report, Coyle was quoted as saying that his departure from JPMorgan had no connection to the financial slowdown.
