The classic formula for a tech startup is that technical founder(s) build an MVP, get funding, and then bring on non-technical staff as required, this leaves the majority of the equity in the hands of the technical founder(s).
However, this is not always the case, Airbnb was founded with Brian Chesky as the CEO and majority shareholder, despite not having a technical background.
I'm currently being offered to join a fintech startup with promise as the CTO and technical co-founder. However, the founder and majority shareholder has no finance or software engineering skills and is not brining any initial cash investment to the table.
Among software engineers, there seems to be a sentiment that ideas aren't worth anything without the skills to bring them into reality, and thus that technical founders bring the most important skillset. However, clearly, this must not be the case otherwise founders like Brian Chesky would not have been kept on as a CEO and majority shareholder.
My question is, how can I evaluate and understand the skillset that my non-technical founder brings to the table that is vital to the success of the startup, and that means he deserves a majority share in the company?
