Prosek Partners

In 1990, Jennifer Prosek founded the public relations firm, originally named CJP Communications, which long focused on brand and reputation communications for the financial and professional services industries. A 2026 PRovoke Media profile gives the founding year as 1991, while the firm’s website and its press releases over the years give 1990.⁠[1][2][3][4][5]

In 2011, the firm grew 20%, ranked fifth among U.S. financial public relations firms by revenue in O’Dwyer’s annual survey, and was named to the Inc. 5000 list of fast-growing companies for the third consecutive year; that year it ranked 11th in the United States and 20th globally in mergermarket’s PR adviser rankings. The firm practiced an internal entrepreneurship model called “Army of Entrepreneurs,” encouraging employees to develop business with an “owner’s mindset.”⁠[3][3][3]

On July 13, 2012, CJP Communications was renamed Prosek Partners and adopted the tagline “Unboxed Communications” and a new logo. Jennifer Prosek said that more than 40% of the firm’s U.S. clients needed services outside the United States and 20% of its clients were non-U.S. companies, so it needed a name that could be used globally. At the time, the firm had offices in New York City and Fairfield, Connecticut, and a wholly owned office in London.⁠[3][3][3][3][3][3]
