Andrew Honnor

Andrew Honnor is the founder and Managing Partner of Greenbrook, a strategic-communications and reputation-management advisory firm he launched in 2012 that specialises in the investment industry (private equity, private credit, hedge funds and venture capital). He brings more than 30 years of financial, corporate and political communications experience. He holds a BA in History and Politics from the University of Exeter.

He began his career working on political campaigns in the UK and the United States and served as a UK Government Special Advisor. He went on to become a partner at Brunswick Group, one of the world's leading financial and corporate communications firms. Immediately before founding Greenbrook, Andrew sat on the Executive Committee of News UK (News International), where he advised the company through the high-profile phone-hacking crisis.

At Greenbrook, Andrew advises global investment firms and their founders on the full spectrum of strategic communications and reputation management — including corporate and sovereign debt restructurings, creditor disputes, litigation and judicial inquiries, fundraising, cybersecurity incidents, shareholder activism, partnership disputes, portfolio-company support, tax investigations, and civil/criminal proceedings. He has been named one of the UK's Top 10 Reputation Managers by Spear's magazine in multiple years (2020–2023, 2025 and 2026). Outside the firm he is a Trustee of Rainbow Trust Children's Charity and a Governor of Lambrook School.

• Not a capital allocator. No verifiable evidence exists that Andrew Honnor makes angel or seed investments personally or through Greenbrook. His firm sells advisory services, not capital.
• Where he adds value to investors and founders: communications as a competitive advantage. In his own framing, effective communication creates an *"enabling environment"* for investment firms — building credibility with stakeholders and avoiding being misunderstood.
• Fundraising-heavy practice: roughly 75% of Greenbrook's work supports fundraising — helping firms establish clear differentiation and a compelling investment narrative to compete for LP capital.
• Speed-of-response conviction: he argues the private-capital sector has been transformed such that firms once had days to respond to an issue but now have *"hours at most, if not minutes,"* so successful firms build *"goodwill and understanding"* proactively, before a crisis hits.
