* Find somebody who already did work with big companies. Make her your test customer.
* I teamed up with an 'old' guy. He is an very experienced businessman and has already a sales infrastructure in some countries. I can focus on development. He makes sure that guys with ties run around and do the selling.
* Prepare to shift from SaaS to shipping hardware.
* Be sure that integration into existing infrastructure is painless.
* Try to talk to the people who would use your software first. With that knowledge go to the person in power to purchase.
* Sort through your friends list and check their companies. Some of my friends are currently calculating how much their boss would save if they could use my product.
* Know your targets. Which person will do the decision? Who reports to and influences this person? (If you would want to sell something technical to my 'old' guy... I would be one of the filters you would go through.)
Unfortunately my landing page is not ready yet. The plan is to divide the information into 'for business people' and 'for technical people'.
Business guys will see how my products saves them money and helps them look good. I will put up some kind of animation to show some use cases.
The technical people can read about the technical concept and how to do integration. As one of the keys in my product is easy integration, I have a ton of examples ready. Although coding is not necessary most of the times, I included some samples in different languages on how to extend the default package.
Hope that helps a bit. Good luck and have fun.
