Horizon Capital, a private equity firm, completed the acquisition of Boston Multi Family Office, a trust and fiduciary services business, from Rockpool, a private equity firm. Financial terms were not disclosed. "I'm extremely proud of what Katherine and Alex have managed to achieve at Boston in such a short period of time. The team have not only proven they can scale the business organically and make add-on acquisitions, but they can do this all whilst keeping people and the Boston culture at the heart of the business," Guy Ellis, Rockpool Investments Partner.
