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

Apple will allow a developer to register 100 UDID devices per 12 month cycle to test via TestFlight or HockeyApp. Having started with TestFlight, I would really encourage you NOT to use it, and go directly to HockeyApp. HockeyApp is a much better product. There is also enterprise distribution which allows you far more UDID's but whether you qualify for enterprise distribution is difficult to say. As part of your testing, I'd encourage to explicitly ask your testers to only register one device. One of the things we experienced was some testers registering 3 devices but only used one, essentially wasting those UDID's where we could have given to other testers. Who you invite to be a tester should be selective as well. I think you should have no more than 10 non-user users. These people should be people who have either built successful mobile apps or who are just such huge consumers of similar mobile apps to what you're building, that they can give you great product feedback even though they aren't your user. Specifically, they can help point out non obvious UI problems and better ways to implement particular features. The rest of your users should be highly qualified as actually wanting what you're building. If they can't articulate why they should be the first to use what you're building, they are likely the wrong tester. The more you can do to make them "beg" to be a tester, the higher the sign that the feedback you're getting from them can be considered "high-signal." In a limited beta test, you're really looking to understand the biggest UX pain-points. For example, are people not registering and providing you the additional permissions you are requiring? Are they not completing an action that could trigger virality? How far are they getting in their first user session? How much time are they spending per user session? Obviously, you'll be doing your fair share of bug squashing, but the core of it is around improving the core flows to minimize friction as much as possible. Lastly, keep in mind that even with highly motivated users, their attention spans and patience for early builds is limited, so make sure that each of your builds really make significant improvements. Happy to talk through any of this and more about mobile app testing.

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.

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. If you need/want to ask me anything feel free to contact me. Mihai

Apps are difficult to fund on IndieGoGo as few are successful, and we rarely take them on as clients. Websites like http://appsfunder.com/ are made for that very reason, but again, difficult to build enough of a following willing to pay top dollar for an app that could very well be free, already existing in the marketplace. A site that is gaining more traction you may want to look into would be http://appsplit.com/. Again, Appsplit Is Crowdfunding For Apps specifically.

I developed and published mobile apps as an individual for several years, and only formed a corporation later as things grew and it made sense. As far as Apple's App Store and Google Play are concerned, you can register as an individual developer without having a corporation. I'd be happy to help further over a call if you have any additional questions. Best of luck with your mobile app!
