I met a billionaire recently. I say billionaire, but I don’t know for sure. He was definitely a paper billionaire at one point before the dot com crash – whether he still is I’m not sure, but it seems like a fair bet. He is a serial entrepreneur who made his money by selling his tech business for >>$1bn (in an all-stock deal), a long time ago. He is now a Euro-elite type, being based on the continent and travelling frequently around Europe.
As it happens, I got into a brief conversation with this chap about how he manages his money. I found it quite interesting. Here are a few snippets as I remember them. Let’s call him David.
David has set up a Family Office which is where the money is managed from. He doesn’t have a ‘day job’ any more, but is clearly a busy guy.

David thinks of his investments in three pots, and takes a specific approach for each:
- Public equities. While David is well aware of the ‘textbook’ investing approach (low fees, diversified assets, don’t try to beat the market, rebalance regularly) he doesn’t directly follow this; he employs some investment professionals to manage the money. I believe he diversifies widely, taking in commodities, hedge funds et al.
- Private equities. David specialises in ‘value-added’ angel investing, mostly (or possibly exclusively) in the tech sector. His investments vary in size from $500k to €10m+. He has 30+ such investments and is reasonably hands-on with several. My impression is he is looking for visionary, ambitious businesses based in Europe, where he can put some serious money to work – and he is not afraid of being the biggest shareholder.
- Real estate. He looks for real estate to ‘double or triple’. I asked ‘so, IRRs of 5-7%?’ and was firmly put in my place – “no; 5% would take 14 years to double; I am talking doubling in 1-2 years”. He is prepared to put in a bit of development/planning / etc effort to create value. He owns at least one large (100+ unit) residential block. Interestingly, he said “if I was simply trying to maximise net worth for least effort/risk, I would invest 100% in real estate”. He doesn’t appear to consider his c.£10m primary residence part of his investment portfolio.

Not David’s actual mansion, but you get the idea
