Have a read of segment's story on indie hackers, their whole product changed when they actually got an entreprise sales guy. Otherwise you need to do more evangelism work.
Do you have a link to the story?
Also I'm really trying to get some enterprise sales guy, I offered share in the company, but can't find the right person. Also finding a real expert in sales is hard for me as I don't know how to tell who's better in sales. Everyone have similar resumes and they all have sales background, but which one is game changer, that I don't know and can't tell. I'm technical person, no skills or knowledge in sales
