Wow, haha I just created an LLC that is a "<number> Labs" company. I don't plan on raising VC or anything public with it, it's just a name to release apps on the app store under.
I was trying to come up with a name and it was exhausting, everything was taken, I was trying "clever names", eventually after strategizing with ChatGPT it gave me the suggestion along the lines of:
"Many people just use their initials, birthdate, or area code, plus the word 'software', 'tech', or 'labs'"
And I went ahead with that and called it a day!
I got lucky when registering an LLC last year for some contract work because despite having a relatively common first and last name, no one had named an nLLC that in my (very large) city. At some point during the process, I had to pick an officer title for myself for some paperwork, but there didn't seem to be any guidelines or restrictions on them, so I just put down my name for that too; I figured that being Firstname Lastname of Firstname Lastname LLC is probably even more clear than "CEO" since it makes it even more obvious that I'm the only one in it.
