well the investor has a name, Longbow Finance SA. not much detail in the autosport article about the CEO and or other investment holdings they have but i imagine more will come out soon enough.

the team name will remain but Peter Sauber will be retiring/leaving his board seat. both good and sad at the same time but overall seems like a new start for the team!
