Duke’s Mayonnaise is currently owned through its parent company, Sauer Brands Inc. , which itself is owned by the private equity firm Advent International as of early 2025.

Who owns Duke’s Mayo now?

  • Duke’s is a brand of Sauer Brands Inc. , a food company that also owns products like Kernel Season’s and The Spice Hunter.
  • In a deal announced in early 2025, Advent International , a global private equity investor, acquired Sauer Brands, making Advent the ultimate corporate owner of Duke’s Mayo.

Recent ownership changes

  • Before the Advent deal, Sauer Brands (and thus Duke’s) was owned by Falfurrias Capital Partners , a Charlotte-based private equity firm that acquired the business in 2019.
  • The 2025 transaction essentially moved Duke’s from one private equity owner to another, while leaving the Duke’s brand in the Sauer Brands portfolio.

A bit of history

  • Duke’s mayonnaise started in Greenville, South Carolina, when Eugenia Duke began selling sandwiches to soldiers during World War I.
  • As demand grew, she sold the business to the C.F. Sauer Company in 1929, which evolved into today’s Sauer Brands Inc.

What this means for the brand

  • Reports on the acquisition suggest Advent aims to provide more resources for Sauer Brands’ growth, rather than changing Duke’s core recipe or identity.
  • Online discussions show some fans are wary of private equity ownership, worried it could affect quality, while others are cautiously optimistic that the iconic tangy flavor will stay the same.
