I'm wondering people's approach for contact enrichment & validation. I.e., you have a list of companies (from Grata or other databases), and you then need to 1) identify names of owner(s), 2), get email / linkedin / phone / address for the owners, 3) do validation for the emails / phone numbers.

My VA and I have worked out a decent process for this, but it involves stringing together a lot of random services, and it's quite time intensive. Our process is below, but curious to hear how others are approaching this.

Identify names of owners
- Search LinkedIn (through the company page) and Secretary of State queries in the state the business was incorporated in

Find their:
- Email & Phone - we use Wiza (cheaper than Seamless and ZoomInfo and just as good)
- LinkedIn - search LinkedIn
- Address - generally skip this step. I have not written a lot of letters

Validation:
- Email: run through Emailable, BounceBan and NeverBounce (gotta keep those bounce rates below 1%)
- Phone: phonevalidator.com - not great but free
