We are a small startup of 10 people (web tech in heavy industry). We have a rather peculiar setup since 2 of our founders and 2 devs are situated in one country (call it location A) while the other founder and 4 devs including me are in another country (call it location B). 1 dev is working remotely. We are one company though.
Until two months ago, there were no devs in location A and until one month ago I was alone with the founder in location B. We then had three people working remotely. I am the head of software development.
Ever since the founders in location A decided to also get devs at their place, things have started to become turbulent.
It starts with them all being of nationality A, while we are very mixed here. Before they also got devs (they essentially just hired them), we had the agreement that the technical development was taking place only at location B, and business development would happen at location A.
They plainly said they needed some devs there, too (of nationality A), to get certain government funding from country A, not giving us a chance to try to convince them otherwise since this would make communication quite hard.
We by now at least managed to have those devs develop one separate aspect of the product, so that we have some kind of clean separation of concerns here.
But this is not where it stopped.
They since then hijacked pretty much all Slack channels by simply using their super user powers. They are not just listening but actively taking part, even in the dev channels where we have some heavy dev talk. They just throw in a question or suggestion which to date has always only led to confusion, waste of time and was plain wrong from the beginning in the first place. Also, they tend to joke around in those channels, while it is clear that we have special channels just for that.
Furthermore, they have begun to start watching each and everyone of us. They monitor what everyone is producing and pretty much only talk with all of the devs directly, circumventing my and 'my' founder's authority. They essentially never talk to me directly.
For example they give a junior dev certain instructions which I only realize a few hours later since the dev thinks this is how it is.
Like this, they are heavily undermining our scrum process by practically assigning tasks as they please.
I have talked with 'my' founder here at location B about this. He then told me that one of the junior devs also approached him about this. But at the same time he says he cannot do anything about it, his hands are tied.
Earlier this year he once told me that he had given up arguing with the other two founders since it didn't lead anywhere.
I told him that he would nevertheless have to strengthen his position to oppose the other founders, but he has given up doing that.
So my question now is: Can I do anything about this? How can I make the founders in location A leave our Slack channels at least? My approach would be to set up regular meetings to inform them about everything they wish to know, at the end of every sprint for example or more often. Is this the right way? Telling them that is also costs a whole lot of their time?
Additional information: To my knowledge nothing has gone wrong in the past that would require supervision. I do assume that they kind of are not happy with 'my' founder and therefore decided to do everything by themselves, however not having any clue about software development and its processes.
