Hey Anirudh, sorry for the delay! Well, I'd definitely start by generating that list of companies with the LinkedIn option. From there, we have the web traffic enrichments to collect some data. Semrush is still in the process of being integrated but if you have an API, you could use HTTP API in the meantime.
You can then filter the results you're looking for by running a few formulas and evaluations, then finding people for those companies that meet your criteria...
