The analogy with tencent and alibaba seems instructive, but not necessarily in a good way. They are both massive bloated platforms that do lots of different disconnected things not very well. e.g. the wechat messaging app contains subprograms for games, payment, flight bookings, etc you can't turn off. They only continue to exist because of network effects, and because they play nice with the Chinese government.

If Recruit works on the same model then they will have the same problem moving abroad that there is no one thing they are better at than an existing company
