I wonder if NOT providing a separate, exclusive account/card/sim etc to a developer is a common trope in fintech. I avoided linking my personal things like hell, and they avoided giving me a damn immutable plastic that would work/get paid for more than a few days. So much friction just because something stopped working or had to get back into oven and they had no replacement at hand. I even had to maintain a separate table for tracking personal balance-replenishing expenses cause no one’s gonna do it immediately. The same people who were chirping about the importance of experimenting, prototyping and not minding any expenses under $$$ or something all day.
