Overview
Sir Kensington's is an American condiment brand headquartered in New York City. It developed in the late 2000s as an alternative to conventional mass-market ketchup and expanded into a broader portfolio of sauces and dressings positioned around ingredient transparency, distinctive flavor, and premium presentation. The brand was founded by Mark Ramadan, Scott Norton, Brandon Child, and Win Bennett. Its first product was ketchup, initially developed in 2008 and commercially launched after approximately two years of product development. The founding concept was to create a more characterful and ingredient-conscious condiment. The original ketchup was formulated with less sugar and salt than standard ketchup and without high-fructose corn syrup. It was presented in glass and plastic bottles and sold in classic and spicy varieties. The name refers to a fictional British merchant created as the brand's mascot. The invented character was intended to convey a whimsical, refined, and slightly irreverent personality rather than identify a historical person. Ramadan and Norton became the company's first full-time employees in May 2010. During that year, the company sold approximately 10,000 jars through retailers that included Dean & DeLuca and Williams Sonoma. Early growth was supported by outside financing, including $8.5 million raised from Verlinvest and individual investors, according to the referenced company history. Sir Kensington's subsequently broadened its range from ketchup into mayonnaise, mustard, ranch dressing, and other specialty sauces. The portfolio has included classic and flavored products such as avocado-oil mayonnaise, organic mayonnaise, Sriracha mayonnaise, chipotle mayonnaise, special sauce, dijonnaise, spicy brown mustard, Dijon mustard, yellow mustard, honey mustard, and multiple ranch formats. A notable product-development milestone was the 2016 launch of Fabanaise, a vegan mayonnaise using aquafaba, the cooking liquid associated with chickpeas, as an egg substitute. The product connected the brand's flavor-led positioning with growing consumer interest in plant-based foods. Fabanaise received product-industry recognition in 2017, including a FABI award and a NEXTY award for innovation. Other recognition included a 2015 sofi award for Special Sauce and medals for the brand's spicy brown and yellow mustards at the Worldwide Mustard Competition. Sir Kensington's also used experiential marketing to make condiments culturally distinctive. In November 2014, it created Fries of New York, a temporary exhibition and French-fry museum featuring preserved fries from New York restaurants, historical material, and accompanying sauces. This activation reflected the brand's emphasis on food culture and playful storytelling rather than only conventional packaged-goods advertising. On April 20, 2017, Unilever announced that it had acquired Sir Kensington's for an undisclosed amount. The brand became a wholly owned subsidiary while, according to the referenced material, remaining independently led and managed. The acquisition placed the independent premium condiment label within the portfolio of a global consumer-goods company. Publicly available reference material identifies Sir Kensington's as an active brand, but does not provide a complete current executive roster, detailed international-market breakdown, or current financial disclosure.
History
Sir Kensington's originated with an effort by Mark Ramadan, Scott Norton, Brandon Child, and Win Bennett to create a more distinctive ketchup. The product was first developed in 2008 and commercially introduced after roughly two years of work. Its formulation emphasized reduced sugar and salt compared with standard ketchup and excluded high-fructose corn syrup. The brand's name came from a fictional British merchant created as a mascot, allowing the company to combine a premium visual and verbal identity with a deliberately playful tone. In May 2010, Ramadan and Norton became the company's first full-time employees. The brand sold about 10,000 jars during that year through specialty retailers including Dean & DeLuca and Williams Sonoma. Its early expansion was financed in part by an $8.5 million investment round involving Belgian private-equity firm Verlinvest and individual investors. Sir Kensington's used this base to move beyond ketchup and build a wider condiment portfolio. The company introduced mayonnaise in 2013. Its mayonnaise range developed into several varieties, including classic, avocado oil, organic, Sriracha, chipotle, special sauce, and dijonnaise formats. Mustard became another important category, with spicy brown, Dijon, yellow, and honey mustard varieties. The company also developed ranch dressing in classic, avocado oil, buffalo, and pizza versions. Products were associated with Non-GMO Project verification, and the range also included USDA-certified organic products according to the referenced material. In 2016, Sir Kensington's introduced Fabanaise, a vegan mayonnaise made with aquafaba, the liquid produced when chickpeas are cooked. The product's name combines the aquafaba ingredient with mayonnaise and signals the product's intended functional similarity to conventional mayonnaise. Fabanaise helped distinguish the brand in the growing plant-based condiment segment and received a FABI award at the 2017 National Restaurant Association Show and a NEXTY award at Expo West. Earlier recognition included a 2015 sofi award for Special Sauce, while the brand's mustard products received gold and silver medals at the Worldwide Mustard Competition. The brand also pursued unconventional promotional activity. In November 2014, it presented Fries of New York, a pop-up French-fry museum. The installation displayed 100 fries from New York restaurants preserved in resin, alongside material about French-fry history and a selection of condiments. The project reinforced the brand's connection to food culture and its preference for experiential, humorous marketing. On April 20, 2017, Unilever announced its acquisition of Sir Kensington's. The purchase price was not disclosed in the available reference material. Following the transaction, Sir Kensington's became a wholly owned Unilever subsidiary. The brand was described as continuing to operate with independent leadership and management. Available public references establish its product history, awards, marketing activity, and ownership transition, but do not establish a full current management list, detailed current sales figures, or a complete list of markets outside the United States.
