Mostly agreed, but your section a goes too high. 400$ per month can't just be quietly expensed in most orgs I've worked for. I'd say max $50-$100 per month.
It’s also about platforms. For example, it’s easy for me to spend several thousand a month in AWS because as a company we spend a double digit millions amount for it already. However, if I want to buy a new product oh boy will I be in a procurement process. For any amount at all from a new platform / vendor I will have to have at least three meetings with increasing audience plus fill out a procurement application at least twice (once with my best guess at what should be in there, second with what the last meeting agreed on). Not price, but existing relations is the biggest factor atm.
That said, I’ve also worked at a startup accelerator on rigorous pricing validation for startup business plans. So I have some ideas about the thresholds and know for a fact that they exist. But it’s never as easy as a single number. If anyone’s interested in discussing some data, feel free to hit me up. Only saas targeted at (mainly) small to large business though.
