For revenue systems and operational process, usually not, but sometimes yes and we will say so.
If you have any paying customers and any intention of hiring, there is foundational work worth doing now, whether that is the CRM or the way the team plans its week.
Leadership coaching is the exception, and it has no floor. A solo founder gets as much out of it as a Series C executive, often more, because the habits are cheaper to build before you are managing a team than after. You are never too early for coaching.
If you are still finding product-market fit, most of what we would build in revenue operations or organizational systems would be premature, and we would rather you spend that money elsewhere.
