A high-flying private investment firm known for its prescient bets on technology companies is losing two more of its top executives.

Partners Feroz Dewan and Caleb Watts are leaving Tiger Global Management, the approximately $20 billion New York-based firm led by Chase Coleman, according to a letter sent to investors Monday obtained by CNBC.com. Two other Tiger Global partners, Andrew Bellas and Alexander Captain, left in January.

"We are deeply appreciative to Feroz and Caleb for their contributions as partners of Tiger Global and wish them the best in their respective next chapters," the 39-year-old billionaire Coleman wrote in the letter.
