Maybe not what you had in mind, but we (TechEmpower, creators of the web framework benchmarks) built a system to randomly shuffle employees among short daily social calls. The calls are not mandatory, but we usually have enough people join for a fun chat. We've found it to be a fun, low-pressure way to keep in touch. It's free to use, if you want to try it for your organization.

We only collect the data we need for the service, and don't use it for any other purpose.
