We were in a similar situation a few months ago when Mitro announced that they were shutting down their service.

Mitro's owner being really nice, they open-sourced the browser extensions, server and mobile applications so we used them to run our own: https://passopolis.com/

We plan to keep the code open-source and we're working hard at the moment to introduce the organisation feature useful for start-ups. We plan to make the organisation feature a premium service so we can justify running and improving Passopolis for as long as it stays useful.
