What Greenbrookmmunications does

Greenbrook Communications is an independent strategic communications advisory firm founded in 2012 by Andrew Honnor and headquartered in London. The firm provides reputation management, transaction communications, crisis advisory, and digital strategy services exclusively through a professional services / fee-for-engagement model, targeting enterprise clients across the investment industry — primarily private equity, hedge funds, credit, infrastructure, real estate, and other alternative asset managers — alongside corporates, entrepreneurs, and sovereign/financial institutions in special situations. Its service portfolio spans ten discrete practice areas: Strategic Communications & Brand Positioning, Crisis Management & Special Situations, Digital Strategy, Specialist Credit Advisory, Shareholder Activism, Litigation & Disputes, Cybersecurity Preparedness & Response, Mergers & Acquisitions, ESG Marketing, and Investor Advisory.

The firm's primary proprietary asset is its Digital Performance Score (DPS) methodology — a framework for benchmarking the digital presence of private markets firms across reach, cadence, engagement, content quality, senior leadership visibility, and paid campaign effectiveness. In its 2026 edition, the DPS report expanded its dataset from 130 to 300 firms and analysed more than 22,000 posts, producing the publicly cited figure that clients collectively reach over 13 million stakeholders via LinkedIn and deliver average digital audience growth of 33% over 12 months. Apart from DPS, Greenbrook has no platform technology, SaaS product, or software offering; delivery is human-led advisory via a team of approximately 35 staff in London.

Commercially, Greenbrook operates a sales-led, relationship-driven enterprise field-sales motion with senior partners directly engaging clients. The firm is founder-owned with no disclosed institutional capital, no parent company, no subsidiaries, and no funding rounds. It is carbon neutral-certified, claims global operating geographies (EMEA, Europe, USA, Asia-Pacific), and is externally validated by Mergermarket (Top 10 M&A advisor in Europe/UK/Nordics; Top 15 globally) and Bloomberg (#1 in the Activism League Tables for five consecutive years).
