No observed cheques. Organisations of this type rarely announce deals, so this says nothing about their activity.
From their own site: “We provide comprehensive and bespoke family office services to ultra high net worth families, trusts foundations and investors around the world – we are essentially a series of single-family offices with the scale and reach of a large institution.”
An announcement gives the size of the round, not the size of this investor's cheque. The only rounds that imply a cheque are those where they were the sole named investor.
