No observed cheques. Organisations of this type rarely announce deals, so this says nothing about their activity.
From their own site: “An award-winning single-family office, Al Zarooni Emirates Investments (ZEI), founded in Dubai, UAE, in 2009, is responsible for structuring and growing a strand of the Al Zarooni family's assets and investments”
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.
