AB testing works well in B2C, but is much harder to make work in B2B.

You can do it, but you can generally only test really large changes, and often if you have good customer communication you can pick up on what the change means with some interviews and showing the customer(s) what the new thing looks like.

This is generally much faster and cheaper (and I say this as someone who adores designing, running and analysing AB tests).
