NEW YORK, June 22 (Reuters) - Tammy Kiely, a technology banker and 24-year veteran at Goldman Sachs Group Inc, is leaving the bank, according to an internal memo seen by Reuters.

Kiely will join Evercore Inc, another investment bank, according to two people familiar with the matter who requested anonymity because no official announcement has been made. Details of her new role could not be learned.

Goldman Sachs did not immediately respond to requests for comment. Evercore and Kiely declined to comment.

Kiely, who was co-head of technology investment banking and global semiconductor practice head, joined Goldman in 1999, was named managing director in 2007, and became partner in 2014.

Kiely's exit leaves Ryan Limaye as the sole head of technology investment banking within Goldman's technology, media and telecommunications group.

As technology dealmaking plunged, a number of top bankers have left Goldman and other firms such as Bank of America and Barclays, often for smaller peers such as Moelis & Co, Qatalyst Partners, Evercore, and Jefferies Financial Group. Kiely's professional plans could not be learned.

Goldman has lost several high-ranking technology bankers this year, including Nick Pomponi, former co-head of global software investment banking who left for Evercore, Rob Chisholm, a partner who moved to Qatalyst, and Troy Broderick, who was named chief operating officer of Goldman's M&A business in May only to leave for Perella Weinberg Partners.

Technology was the top sector for mergers and acquisitions for eight consecutive quarters until the second quarter of 2022, when a bout of inflation forced central banks to raise interest rates, weighing on tech stock valuations.

Global deal volumes in the technology sector have dropped by more than half so far this year, according to data from LSEG Deals Intelligence. (Reporting by Greg Roumeliotis, Anirban Sen and Milana Vinn in New York; Editing by Daniel Wallis)
