Bring consumer instincts to enterprise AI sales and you will break yourself against a wall you did not know was there. In consumer markets, first-mover advantage is often decisive: capture the user, build the habit, win. In B2B, that logic inverts, and the thing that inverts it is the buying center.
The buying center is the committee that must collectively approve an enterprise purchase, where everyone can say no and only some can say yes. Your champion loves the product. Wonderful, and almost irrelevant on its own, because standing behind the champion is procurement wanting defensible pricing, security wanting to know where the data goes, legal wanting to know who is liable when the model is confidently wrong, and an executive sponsor who mostly wants to not appear in a headline. Any one of them can kill the deal. Your champion's enthusiasm cannot resurrect it.
This is why explainability and audit trails are not features in B2B AI. They are gates. A model that produces brilliant outputs it cannot justify will not clear procurement, because "the AI decided" is not a sentence legal can say out loud when the decision gets challenged. The enterprise buyer is not running your optimistic math. They are minimizing the probability of a catastrophic, career-ending, board-slide-generating failure. In that objective function, a slightly worse product with fully auditable behaviour beats a slightly better black box every single time, and it is not close.
The uncomfortable implication for founders is that the work which wins enterprise deals is the work they least want to do. Improving model performance is intellectually satisfying and endlessly demo-able. The enterprise does not buy the demo. It buys the answer to "what happens when this is wrong, and can I prove to an auditor that we did our diligence." Build for that question first. Performance gets you into the room. The boring machinery of trust, the logs, the citations, the permission controls, the data-residency guarantees, is what gets you the signature. Founders who learn this early close deals. Founders who learn it late write blog posts about how long enterprise sales cycles are.
