The firm has remained independent throughout its 35-year operating history.
The Founder and the Founding Era
Jen Prosek launched the firm in 1990 with a focus on financial-services communications. The firm built its reputation through the 1990s and 2000s with mid-market financial-services clients including HSB, GE Capital, and Travelers Insurance. The defining moment came in 2015 when Goldman Sachs selected Prosek — then an up-and-comer relative to the established financial-PR firms — to handle communications for its asset-management division. The Goldman win catalyzed a sustained growth cycle that took Prosek from a 230-person operation with around $60 million in revenue in 2020 to roughly 400 people and $120 million in revenue by year-end 2024 — sustained double-digit growth across most of the past decade.
The Abu Dhabi Office and the Middle East Expansion
In 2024, Prosek launched an Abu Dhabi office led by Managing Director Diana Estupinan. The office anchors the firm's emergence in Middle East financial communications and supports clients including Saudi Arabia's Public Investment Fund, the roughly $925 billion sovereign-wealth fund. The Abu Dhabi expansion followed the London office's continued growth and the firm's broader push into global capital-markets communications. In January 2025, a former Blackstone Senior Managing Director joined as Partner in London.
The Roster
Prosek's client list spans the senior tier of United States financial services. Named clients of record have included Goldman Sachs, Bridgewater Associates, Vista Equity Partners, Veritas Capital, HPS Investment Partners, BlackRock, the Public Investment Fund of Saudi Arabia, HSB, GE Capital, and Travelers Insurance. The M&A practice has supported deal sequences across Vista Equity Partners' sale of PowerSchool to Bain Capital, Veritas Capital's recapitalization of Cotiviti, and HPS Investment Partners' acquisition by BlackRock.
Service Offering
The firm delivers financial communications, M&A communications, investor relations, corporate reputation, crisis communications, public affairs, sports-business consulting, and a signature conference concierge offering — a service line that supports client leadership through industry conferences and major events. The firm has invested significantly in data, analytics, and measurement capabilities under the broader brand-strategy banner led by SVP Jen LaFiura, who joined from American Express in December 2021.
Position in the Category
Prosek sits at the top of the independent United States financial-communications category, directly competitive with the largest holding-company-backed financial-PR practices. The peer set includes FGS Global (the WPP-owned market leader), Brunswick Group, Joele Frank, Wilkinson Brimmer Katcher, Sard Verbinnen & Co., Edelman Smithfield, Abernathy MacGregor, H/Advisors, and Gladstone Place Partners. Prosek differentiates on the combination of senior independence, the second-place mergermarket M&A ranking, the Abu Dhabi presence, and the sustained double-digit growth track record.
Reputation Arc and Recognition
Prosek was named PRovoke's 2021 Global Corporate/Financial Agency of the Year and is consistently included on PRovoke's annual list of the Top 80 United States agencies. The 2024 partner-promotion class added three new partners — Alex Jorgensen (investor relations), Katie O'Reilly (conference concierge), and Jim David (public affairs). Jen Prosek was named to the 2025 PRWeek Power List at #41 and the 2026 Observer PR Power List at #11. The firm ranked among the top five advisors on corporate activism in 2024.
