Andrew Honnor
Spear’s Review
Andrew Honnor is the founder and managing partner of Greenbrook, a communications agency that specialises in the investment industry. Greenbrook advises on reputation management around mergers, acquisitions and exits, as well as complex debt restructurings. His firm has also carved a successful niche offering clients in the private equity and hedge funds space insight around fundraising.
When dealing with top-tier entrepreneurs and private capital managers across Europe and the US, for whom Honnor offers expertise on crisis management and investor communications, discretion is key.
Honnor cut his teeth in the communications world as a special adviser in the UK government’s Department for Digital, Culture, Media and Sport, and later worked as an associate partner at Brunswick. In 2011, he served as an adviser for News International, helping the publisher deal with the fallout from the phone-hacking scandal.
