While I’m sure the question is a joke or half-joke, there’s an important variant of this question that is worth exploring.
Yes, founders need to sell a vision and sell ahead. Investors want to see that. But …
There’s nothing that kills a financing faster than something in the pitch that is outright wrong. Especially something that is important.
As a small example, there have two recent start-ups where I really wanted to invest and the founders said they had closed $X0,000 in revenue with their first few customers.
In both cases, I called these customers and … well … it turned out they weren’t actually customers. Not yet, at least. In one case, they were all unpaid pilots with draft contracts for the $$$ amount the founders claimed. In the other case, the deals were again pilots, this time paid, but only one-off deals.
To me at least, this is a stretch too far.
Other examples include claiming management team and/or key team members … that aren’t actually signed up yet. Or are really just advisors, or part-timers.
Another, more subtle example is complete misunderstanding of the competition. If I know your competition and you state something that is completely wrong about the space or them … I’m out.
My “favorite” are fake and pseudo metrics like “QRR” where founders combine three months of revenue into one Quarterly Recurring Revenue number to conflate their revenues. Enough.
