Bankers who left for startup: Where are you now?

Ignore title. Recently left banking for a BizDev/Ops role at a very early-stage startup. Wanted more ownership, upside, and the opportunity to actually build something.

A couple of weeks in, I'm already questioning the move. The work feels pretty scattered and unstructured, and despite being in an account management role, I spend a surprising amount of time scheduling meetings, coordinating logistics, and handling administrative tasks. Sometimes feel more like an executive assistant than someone driving meaningful business outcomes.

I genuinely miss the analytical work and structure of banking, but can't tell if this is just part of working at an early-stage startup or a sign that the role isn't for me.

For those who made the jump from banking to startups, what was your experience like? Did the work eventually become more meaningful, or did you end up returning to finance?

Also, how long would you recommend sticking it out before calling it quits? Don't want to jump ship prematurely, but also don't want to waste time in a role that isn't developing the skills I want.
