Normally I see things written this way :
Developed by Joe Doe
But I have also seen instances where it says:
Developed by Company Inc.
Now, I know it doesn't make sense to say:
Developed at Joe Doe
But I have sometimes seen it say:
Developed at Company Inc.
What's the difference between saying something was developed by a place versus saying that something was developed at a place?
Is there even any difference between those?
My initial assumption was that maybe someone who isn't part of Company Inc. used their facilities and did their development there, but now I'm not sure.
