“We are thrilled to welcome Back to the Roots to the Echo portfolio,” said Benjamin Levy, vice-president of Echo. “The company’s core mission to reconnect people back to where food comes from exemplifies the transparency, vision and social justice shared by many of the companies Echo partners with.”

Also based in Oakland is Nona Lim, a manufacturer of non-G.M.O., dairy-free and gluten-free soups, bone broths and portable meals.

“The convenience and accessibility of Nona Lim’s soups and broths appeals to the millennial generation, but so does the variety and boldness of their Asian-inspired flavors,” Mr. Levy said. “We’re seeing the popularity of ethnic foods growing at a steady pace, while consumers steer away from traditional flavors like ‘beef’ or ‘chicken’ and toward bold and exotic flavors from around the world.”

Wilde Brands makes protein snacks and is credited with creating the first non-G.M.O. slow-roasted meat bar made from local grass-fed beef and free-range chicken.
