Ask HN: Sales hiring tips and battle stories?

Dear HN, I have a clear idea of the kind of customer that I would like to work with for developing my next AI product. I even found one good candidate in my own network, but he's locked in a long-term contract with a competitor. So I guess now's the time for me to hire a proper sales person so that they can find potential customers and introduce me. I'm hoping that some of you with successful startups would be willing to share some tips and/or funny battle stories about how you hired your first non-co-founder salesperson. So far I watched this excellent talk: https://businessofsoftware.org/2010/10/paul-kenny-at-business-of-software-2010-selling-sales-to-techies/ Any other talks you can recommend?
