FWIW I've worked with "experienced" founders who also had no idea what they were doing (in many but not all ways). There's never a guarantee that you won't be working for people who will make you deal with their mistakes.
Heck, there is no guarantee that you won't be working for someone like that in any type of company, regardless of "maturity" or sector.
Bad managers (and most bad management - from death marches to protoduction - can be boiled down to "makes the people who report to them pay for the manager's mistakes") exist even in supposedly mature companies with good corporate cultures.
