"Founded" can have different meanings, no? I can sit with my flatmate right now and found a label, but if you ask the government when it was founded, they'll say June 2017 as that's when we'll have the paperwork done. Or maybe not until next year if we need to raise capital for it. That means it was both founded today (informally), but officially (formally) not founded until some time from now. The relationship text doesn't give further clarification as to what it means by "founded".
