Maybe use instant data scraper at vc's company list. (Not in clay) It's a Google extension.
Get the company names, then use open ai API
to get the founder's LinkedIn ( get me the names of the founders of <company>) then run another column ( <founder name> LinkedIn)
Then use either full enrich API or any email enrichment to get their email.
Or use Apollo, just add in the founder/co founder in the job title and company keyword tab the VC name or their batch date (techstars2022, YC S24)
Copy the link and use apify Apollo scraper to get the rough list with emails included.
Then import on clay for further enrichment.
