You’ve got a big pitch/demo coming up and an even bigger list of stuff you’d love to fix about the product before then.
One way to decide which stuff to prioritise is to mentally walk through the demo and just fix all the bits you find yourself apologising for. “Oh, yeah, sorry about that… just click over here. No, there. Yeah. We’ll have that fixed in the real version.”
Apologies ruin the tempo of a demo. It’s better to have a zero-apology demo (or trial) than to have some extra features. A polished core gives you a good foundation from which to tell the story of all the exciting new stuff which is still coming up. Shaky features in this context undermine your credibility.
