There's some of that but I remember 15 years ago this investor in our startup emailed the founder and misspelled the name of the startup that they had just pumped a significant amount of money into :-)

The founders said it was very 'senior' of him and laughed about it. But it's also kind of indicative of seniority because senior people aren't wasting time looking up the correct spelling of a company name - they get the email out with the salient details with the right amount of time invested into it. You want to be dialed in but also if you're doing lots of stuff at scale it doesn't really matter what the name of the startup is. Ideally you did the right diligence before the decision to invest was made but then at that point only a few key things matter and are worth keeping in hot memory any more - things like where the founders went to college (in case it helps with a future connection), what the market is (in case it helps with a future connection), what they need help with (in case it can be brought up with a connection), etc...
