Having some marketing experience, I would say that most marketers would not be able to do this. That is, if their experience is working within marketing departments. What you really need is people who have done exactly what OP asks about, and in that role done some tasks that could be classified as marketing. But a lot of marketers have never launched a new tone side project or startup zero to one, so they don't know how to do it. Modern marketing is unfortunately siloed with a very narrow purview that is not at all close to covering the 4Ps, which is what marketing really should be about.
