As a start up company you probably don't have much money to spend in advertizing, entertainment etc. so having been in this position before I would advise to connect with resources you have within your organization to quickly get in front of the right people (Owners/publishers). Someone should know someone who can get someone in to see these people. If I didn't know somebody I always dissected my contacts to call in a favor for an introduction.
Now if you have money to allocate to this task, I would hire someone like myself to get you in front of the decision maker on the first meeting and pitch the pitch leaving it up to your best guy/girl to close.
Best of luck, I hope it helped!
Do you have a "business plan" or "road map" on where you are now & where you'd like to be? If not, it will be VERY difficult in scaling your business, or even maintaining it at it's present level. Do you have the resources (financial, manpower, opportunities, etc.) to grow your business, or support the growth you think you want? Do you have partners, or joint-venture affiliates?
I'm not sure I know exactly what you mean by "scale up"? If you mean ger more business then you need to evaluate your value proposition vis-a-vis other firms providing the same knid of content. In other words - what is faster, better , cheaper about your content than theirs?
You can scale up your business through solid marketing practices, sales systems, and operational systems. Once those are in place then you can grow the business as fast as you would like without any trouble.
