LinkedIn2Username is an OSINT tool that generates username lists from companies on LinkedIn. What’s great about LinkedIn2Username is it’s easy to setup and doesn’t require an API key. You need only supply your LinkedIn username and password to operate it. One disclaimer before we get started is this tool will likely not deliver quality results from a pseudo/alias account unless you’ve built many connections through it. Additionally, LinkedIn will cap search results to 1000 employees so if you’re scrape a very large company, results will vary.
