When Attrition Attacks: Yahoo’s Latin America Head Departs

According to sources close to the situation, Guilherme Ribenboim, VP and managing director of Latin America and U.S. Hispanic markets, has left Yahoo for another job at a start-up.

The 12-year Yahoo veteran, who is located in Brazil, is widely respected at the troubled Silicon Valley Internet giant and leads an area that is growing for it.

[UPDATE: A Yahoo spokeswoman confirmed the departure of Ribenboim.]

[UPDATE NO. 2: Also leaving: Connie Lee Schiefer, the well-regarded Yahoo veteran of more than eight years. She was VP of product management at Yahoo’s cloud platform group.]

Sources said that attrition — already a big problem at Yahoo — is about to hit the company hard. While the board and its top leaders try to figure out a strategy — either a sale or whatev — in the wake of the firing of CEO Carol Bartz, Yahoo has yet to put in place a new plan to hold onto talent.

“The people walking out the door is about to become a flood, unless management acts,” said one employee in a common sentiment among people I have interviewed at Yahoo.
