I suggest founders start with a low cap and only raise it once they have 1 year of money. A lead can come in later and perhaps set a higher price but I agree with you — dangerous to start high by yourself, as you can exclude investors unnecessarily.
There are ~3 slides I’m missing here, the most important is the title slide, then the raise/ask slide and lastly competition. I prefer competition to come up in the problem and how it works slides, then the Q&A if the investor is diving in deeper. If your competition is so significant it will influence the seed stage raise, then it may belong in the main deck, versus the appendix.
We invested time in building a complete profile of a candidate in advance of the interview. This profile was accessible in advance of the interview day and interviewers were asked to read the documents and ask questions before interviewing. We found this reduced interviewers defaulting to their standard pattern matching.
