NEW YORK — Carlos Altschul has been named president and chief executive officer of Icelandic-style yogurt maker siggi’s. He replaces Bart Adlam, who has left the company to pursue another opportunity.

Mr. Altschul joins the company from organic yogurt brand Stonyfield, where he was vice-president of sales, leading field sales, go-to-market strategies and shopper marketing across the portfolio. Previously, he held senior roles at Danone, overseeing sales strategy and category management under the master brand portfolio.

“I’m very excited to have Carlos join the team,” said Siggi Hilmarsson, founder of siggi's. “I’ve known him for quite some time and know he will be great for siggi’s as we continue to grow. Coming from Stonyfield, Carlos knows firsthand the importance of upholding our brand values of clean ingredient labels and lower sugar, the values which have made our brand so highly relevant today. His strong expertise in the yogurt category, both in natural and more traditional classes of trade, is also a great boon to the siggi’s team.”

At siggi’s, Mr. Altschul will be responsible for bringing forth new and aggressive go-to-market strategies and innovations, expanding distribution and accelerating brand awareness.

“I’ve admired how siggi’s has not only pioneered a new product segment in the category but is also creating the next chapter for the entire yogurt category,” Mr. Altschul said. “I look forward to working closely with the team to establish a clear vision for what is next, and I am thrilled to be part of a company with such a tremendous growth trajectory.”
