(Sorry I'm being vague, but I'm not sure I'm not sure what's public knowledge)
The cap is moderately above the high subscription tiers, and managements/the executives were clearly extremely concerned about how expensive it would be if we all or even mostly came close to hitting it. I heard that they originally wanted to go lower but the developers in the pilot program blew past their planned limit very quickly.
As for the company, its almost entirely B2B SaaS (I think it has some offerings that are used by consumers, but they're mostly/entirely paid for by another business on behalf of their customers), and they have developers all over the world, although the headquarters and biggest group of developers is in silicon valley (my office is in the midwest).
