I spend my time doing marketing and bizdevy stuff. However, I'm still really involved in any major development efforts, we regularly at least 3 times a week discuss code, I still contribute code, and we often pair program.
My contracted developer, Henrique, is really not just a "contracted developer". He's a CTO caliber amazing architect and I consider him a partner in the project.
The current codebase is the 3rd-ish iteration on the same theme. The first and second iterations were built primarily by me, so I had a pretty good sense of how I wanted everything built for the future (incidentally, my "pretty good sense" was totally garbage, and if i started over again, it'd be totally different... again...)
Even the early versions of the current iteration were largely a collaborative code effort between me and Henrique, either hitting milestones by "divide and conquer" or by pair programming.
As the product began maturing, I have been slowly shifting away from code to marketing and CEO/CMO-y stuff. Basically, I am not good at being a heavily involved CTO and marketing. My perspective here is that development CAN be outsourced, though it may not be easy, but good marketing and bizdev can NOT. However, we try to be analytics driven, so Henrique is also deeply involved in the marketing and analytics, but we just have a focus on our own individual domains.
2. Looks like you're now making a profit but a really small one... for May 2013: $5660 - $2377.23 - $1808 = ~$1500, is that right?
Correct.
3. Sounds like your revenue vs costs/expenses scale linearly as well, but more business = more margins, is that right?
In principle, I can squeeze out a little more edge once I get to bigger scale, but there's a floor on the cost of reports, so I'm more interested in growing the audience size than optimizing the costs here. I'm also below the threshold where reporting companies really want to cut me breaks, so I'll have to wait a little further before that.
The "cost of reports" component scales linearly, but I expect the fixed costs to be pretty static for very large ranges of total users/applications. It'll be stepwise-ish, but I'll probably flat until at least 10x more sales from here.
