We (I work at a crypto startup with about 100 employees now) finally reached the size where we need both internal and external docs. Before, we lived with whatever crappy confluence page I could write. Or we just relied on word of mouth. And that works when you have fewer employees and clients. But there are more now (of both) than I can keep up with. I think a lot of crypto companies are in a similar position right now. Were actually a bit ahead of schedule

That's why we just hired out first two technical writers.

I cannot comment on EA. Do you mean Electronic Arts? Sorry for my ignorance...
