While a direct phone number is helpful in terms of getting to talk to who you want to talk to, even more valuable is a 'warm intro' from someone that the person knows. Warm introductions depend on a personal relationship with someone, so that kind of service can't be as easily automated and would be extremely valuable. Because it would inherently be impossible to effectively pull off for the long term at a large scale, you'd have to charge a lot for that service though.

One possible way to make it more scalable is to have a lower priced option which involves a warm intro to a gatekeeper, instead of the final target. Gatekeepers might be easier to befriend, and might even be open to helping occasionally in exchange for a cut of your revenue.

I have several ideas on how you could pull this off in a psuedo-automated way, that would let you quickly implement the idea in a low cost way. If you'd like to discuss it further let me know,

best,
