You need to look at your startup in stages. If you are getting revenue in your business and have 1400 subscribers, what execution plan do you have in place to GROW, and how much money do you need to do so? Even at this level, I believe you are still considered as early stage seed and still would be looking for small/med Angel to help you boost your existing traction. You are in a good position to look for smart money investor that will have the contacts and network to take you to Series A. Since your company is enjoying good cash flow, take your time to find the right investors that will maximise your evaluation for the next round.
