There is always someone else.
No matter how skilled you are, no matter how wonderful your product is, no matter how supposedly unique your culture is. There is someone else out there offering the exact same thing, covering the exact same spot, addressing the exact same problem.
And you have two things to do to mitigate this problem.
First, understand who someone else is – and by the way, this is a decision of those you are serving.
Second, be as specific as possible in figuring out and expressing what you are.
The alternative is most of B2B marketing nowadays: companies with fantastic products and services playing in broad and fuzzy markets to increase their customers’ productivity. All the same type of better, faster, cheaper.
