I have been getting repeated emails saying something along the lines of "We have a family office who has a strong interest in making an investment into <MY_COMPANY_NAME> industry. Can we set up a time to discuss this opportunity?". They are signed with different names, always female, and coming from email addresses with a TLD of .help or .shop

It's obviously a scam and I am not replying, but I'm curious what the scam is here.
