Overview: What Prosek Partners Does
Prosek Partners is an independent financial communications firm founded in 1990 by Jennifer Prosek. The firm has grown over three and a half decades from a niche financial communications boutique into a global operation specializing in financial services, M&A communications, investor relations, corporate reputation, public affairs, and sports business consulting. Prosek is a fixture on the mergermarket rankings of North American M&A advisors and is among the top advisors on corporate activism.
Why It Matters
For readers researching Prosek Partners, three facts shape how the firm operates today. First, Prosek grew 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 over much of the past decade. Second, the firm's 2nd-place ranking in mergermarket's 2024 North American M&A advisor table by deal volume (behind global giant FGS) places it directly competitive with the largest PR firms in financial services. Third, the 2024 Abu Dhabi office launch — including Saudi Arabia's $925 billion Public Investment Fund as a client — marked Prosek's emergence in Middle East financial communications. The firm's "conference concierge" offering is a distinctive service-line approach in the category.
Why M&A Communications Is Different
M&A communications operates under regulatory constraints, market-sensitivity rules, and stakeholder dynamics that distinguish it from most consumer or corporate PR work. Successful M&A communications requires fluency across several specialized capabilities.
Securities law and disclosure timing. M&A announcements are timed to filings with securities regulators (the SEC in the US, the FCA in the UK, equivalent regulators elsewhere). Public companies have strict disclosure rules about material non-public information; deal communications must align with regulatory filings, proxy statements, and earnings call cycles. Mistakes — pre-announcement leaks, asymmetric disclosure to selective audiences, off-script executive comments — can trigger regulatory inquiries and shareholder lawsuits.
Multi-stakeholder audiences. An M&A announcement has to land simultaneously with multiple distinct audiences: buy-side and sell-side analysts, institutional shareholders, retail shareholders, employees of both companies, customers, regulators, the trade and business press, and increasingly social media and AI-driven discovery. Each audience reads the same announcement differently. Effective M&A communications anticipates each audience's questions and prepares specific message frameworks for each.
Deal sequence and choreography. Major deals unfold over weeks or months: rumor management, deal announcement, regulatory filing, shareholder approval, antitrust review, integration planning, day-one communications, and post-close integration. Each stage has its own communications requirements. Prosek's M&A practice has supported deal sequences across Vista Equity Partners' acquisition of PowerSchool (sold to Bain Capital), Veritas Capital's recapitalization of Cotiviti, and HPS Investment Partners' acquisition by BlackRock.
Activist and contested situations. Hostile bids, activist campaigns, and contested deals operate on compressed news cycles where messaging timing can move stock prices. These situations require crisis-response calibration and proxy advisory engagement (ISS, Glass Lewis). Prosek ranked among the top five advisors on corporate activism in 2024.
History and Ownership
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 Partners — then an "up-and-comer" relative to the established financial PR firms — to promote its asset management division. The Goldman win catalyzed a sustained period of growth, with the firm expanding from a 230-person operation in 2020 to ~400 people by end of 2024. Prosek has remained independent throughout its history.
