As someone who buys a fair amount of SaaS/Cloud/on-prem software (~$5-10 mil annual spend), the amount of B2B and recruiting spam I get is overwhelming. My public contact info is basically burned at this point - email, LinkedIn, work phone, etc.

I have a second profile that only gets shared with actual people that I have actual relationships with.

I would say about the only way to get past that filter is via some kind of content marketing that gets shared by folks or an actual direct person to person introduction.
