How to Accurately Scrape Sales Team Size for Lead Lists

Curious how other people are doing this: I'm trying to scrape how many sales people there are at each company for a lead list. So number of SDRs/BDRs etc. Tried a few claygent prompts that got it totally wrong trying to scrape Linkedin. Recently switched from Apollo to Smartlead data which isn't amazing so going the people level data at companies isn't going to work. How else are people doing this?
