This may help. Think this way: the recruitment process of these companies is designed to acquire neurons, human thinking power in the same way they need electricity, disks or servers, not personas.
They use puzzles as benchmarks. Why do they should care about you as a person or your feelings?
I think +1000 users is a pretty nice number to find your business model, in your case, what are your customer acquisition cost and your churn rate? is your model sustainable?
So you don't have an idea? Here is mine: what about spending 3 years tracking other startups' evolution, interviewing entrepreneurs, angels, VC's etc..., with all this information and contacts spend 3 months preparing a kickstarter campaign for a book about startups and entrepreneurship, 9 months to write your book, and with all this information/contacts and press you have collected 1 year building something thinking about what the would would need two year later.
I absolutely agree with other comments here. This is not a software startup, is a service and nobody cares about the software that supports it. You should concentrate you efforts on provide the best support you can and not the technical details.
