Ask HN: How to start traction with a enterprise startup?

Hey Guys, Me and 3 friends started a startup to help business to recruit faster. Our service uses a Vídeo CV in the way to avoid job interviews and have some filters to help the recruiters.

My question is, how do I really dig into the market? A consumer startup is kinda easy, in my opinion, but when I have a B2B solution, how can I make the first step? Sometimes I feel so slow when I have to have 3 meetings in a time span of 3 weeks to start a trial of my service.
