That's pretty irrelevant to the point though. They had the funding to hire experts in every critical role, buy a factory and the tooling needed, contract with automotive giants like Magna Steyr, build a global logistic chain including dealer network, run a worldwide marketing campaign (which btw almost certainly leveraged Ineos' existing marketing capabilities), etc.
Actual 'startup' companies do not have that kind of umbrella of safety and financial runway. Lack of in house automotive knowledge was about the easiest challenge to overcome compared to all the rest, and being a part of the Ineos corporation means it was actually feasible. They are hundreds of miles away from being a startup.
