Depends on a type of company, I work at a mid-sized startup and through lifecycle of this company there were times when we've had architects and there were times when we haven't. Rn we don't have and a lot of decisions is made within teams and we just try to keep communication about what's needed for business tight

Understandable. I worked mainly for 100+ people companies and the tech stack impacts team interoperability, hiring, licenses, life cycle management etcetera.
