Is there an ad server that will allow us to integrate sponsor ads into our app?

To answer your questions: 1) Mobile companies at your stage usually raise angel funding at a valuation equivalent of $5,000,000 for US based companies and $4,000,000 to $4,500,000 for Canadian companies. 2) The valuation is a function of how much you raise against that valuation. For instance, selling $50,000 at $5,000,000 means you are selling debt that will convert into shares equal to roughly 1% of your company. 3) I would encourage you to check out my other answers that I've recently written that talk in detail about what to raise and when to raise. Given that you've now launched and your launch is "quiet", most seed investors are going to want to see substantial traction before investing. It's best for you to raise this money on a convertible note instead of actually selling equity, especially if you are intending on raising $50,000 - $100,000. Happy to schedule a call with you to provide more specifics and encourage you to read through the answers I've provided re fundraising advice to early-stage companies as well.

You won't find anyone worth adding to your team willing to work for equity only, no matter how compelling your product and business is. The realities of the talent market for mobile developers anywhere is such that a developer would be foolish to work only for equity unless they are a cofounder and have double digit equity. Happy to talk about hiring and alternatives to full-time hires.

I would suggest launching in a foreign app store only (ex: Canada). That will allow you to get more organic users to continue iterating without a big push. I got this idea from Matt Brezina (Founder of Sincerely, previously Xobni) https://clarity.fm/brezina - he's the man when it comes to testing & iterating mobile apps.

My 2 favourite are: - www.uxpin.com - www.flinto.com Flinto is by far my favorite for mobile. I also us www.balsamiq.com for anything wireframe. Sometimes I jump into Sketch http://www.bohemiancoding.com/sketch/ for more high fidelity mockups using their Mirror feature http://www.bohemiancoding.com/sketch/mirror/ Hope that helps. P.S. There's a tonne of Mobile UX experts on Clarity, many $1/min - call them, you'll learn so much. my2cents.

There are two sides to that question. One is the mobile app itself and the other is the backend. If I misunderstood in any way and you didn't mean "native" app I apologize in advance. On the backend, there is no clear cut answer to which is the "best". It depends solely on the developers you are able to get. We for example use Node.js , mongoDB, redis, elasticsearch and a couple of proprietary tools in the backend. But you have your pick of the litter now both on the backend api and the datastore with the myriad of options available and touted as the "best" currently on the market. Now on the app side again it solely depends on what you need your mobile app to do. Experiencing first-hand "develop once, run anywhere" I can say it's more like "develop once, debug everywhere" to quote a Java saying. We have tried Phonegap and Titanium Appcelerator and we have switched to native (ObjC and Java) after a couple of months of trying to go the hybrid route. The reasons behind the choice are as follows: - anything that breaks the pattern of how those frameworks NEED to operate is just a huge technical debt that keeps accruing a huge interest. - anything that uses css3 accelerated animations on Android is buggy at best and slow as hell at worst on any lower (< 4.1 I think) versions of Android I hope this gives you some insight.
