Whilst entirely agree with Gregg's approach, I wouldn't use his response rates as a metric to measure your own response rates. Cold approaches like this tend to have significantly higher response rates when you are a company like Stripe.

I would expect that most of the people they are approaching have heard of Stripe and are familiar with their high calibre team. If the same people are approached by a company/startup they have never heard of, the response rate will be very different.

It's still a fantastic approach and arguably the best approach regardless of how well or little known your company is.
