That said it takes time to build trust. You can establish it over time by building authority and offering social proof in any industry.
Going direct to customers is a good way to start revenue but it's tough to scale. HP sells 80% of its revenue through partners. Instead of going direct to customers you should build a channel sales program and build up partner relationships.
Partners you work with should have clients already, clients you want. Clients that trust these partners because they do a good job.
That's how you get into enterprise quickly and scale.
I have built and sold five companies in the last 7 years. I was CIO at a $50M/year sales organization, now I am starting to take startups through a probono training on how to do sales for enterprise if anyone is interested in joining our sessions. No cost to anyone for as long as I enjoy hosting it. It's over google hangouts. Email me hn (at) strapr (dot) com to get on the list.
