In B2B purchasing, one of the main reasons a product gets bought over the competition is that one product is viewed as a safer bet than other potentially better offerings. A thought captured rather nicely in the phrase "No one ever got fired for buying IBM" but as Tomas Tunguz comments below, to drive growth, you need to do better than just competing on reputation. That's when you're effectively selling the personal advancement of your clients. You need to convince the client that if they buy your product, they are going to look like rockstars.

There’s the risk of a failed deployment, the risk of picking a suboptimal vendor, and the risk of budget overruns.
