Only if you’re talking “2 pizzas can feed the entire company” stage, really.

Early stage b2b salespeople would, pre covid, spend all their time in between customer meetings in the car on the way to next one. Hard to implement a solid early stage marketing strategy behind the wheel.

Doing marketing or sales well is a full time job. Marketing is long-term focused, sales is short-term, a person doing both gonna be heavily incentivized to do sales because marketing can make 3/6/9 months to show results.

In practice, every person I have ever seen hold a DevOps title would have been called a sysadmin or something to that effect 10 years ago. They’re really not working on product features, even though they know how to code.

Similarly, yes, there’s plenty of people that have a grasp of both sales and marketing to some degree. But there’s only so many hours in a day.
