Product companies tend to have more product managers and less project managers (they’re usually called something else, like simply software engineering managers or tech leads who have take on the project management duties).
Traditional enterprises and software consultancies tend to be organized around projects rather than user-centric products and their features, so they will more often have project managers instead. The product responsibility in turn tends to become more ad hoc, sometimes with someone assigned as a “product owner” outside their regular title.
(My personal view: if a company has project managers and product owners, that’s a sign that it’s probably not the place for me.)
