The sales vs marketing debate is the wrong debate.
Most companies treat sales and marketing as separate functions with separate budgets, separate targets, and a long history of mutual suspicion. Salespeople complain that marketing generates bad leads. Marketers complain that sales ignores their assets. Both teams compete for credit when things go well and assign blame when they don’t.
This structure is so common it feels inevitable. It isn’t.
Peter Drucker wrote that a business has two — and only two — basic functions: marketing and innovation. Everything else, he said, is a cost. There’s no mention of sales as a distinct function. That’s not an oversight. Drucker’s view was that marketing, properly understood, encompasses the entire organisation seen from the customer’s point of view — not a department, but a way of operating.
Dave Packard made the same point more bluntly: marketing is too important to be left to the marketing department.
The same is true of sales.
I learned this the hard way. Early in my career, working in traditional companies with clear departmental lines, I felt the friction between sales and marketing as a constant background noise. We were in different camps. I was too junior to name it and too busy to question it.
It was only when I joined a startup — small enough that nobody had the luxury of a silo — that I saw what the alternative looked like. Salespeople contributed to content. Marketers sat in on customer calls. Deals were everyone’s problem and everyone’s win.
The companies that grow consistently aren’t the ones with the best sales team or the best marketing team. They’re the ones that stopped treating those as different things.
