How do we create a "Call waiting" option for a VOIP mobile app using Twilio even though Twilio does not have an SDK that supports this function?

I have built two software companies by hiring out the development work. I sold one for a decent sum during the dot com era (circa 1999). I remain a shareholder in the other one. I currently work with amazing development company on behalf of one of my clients. Here are some things to consider. 1. Do you really want to give up equity? If not outsource. 2. How fast do you want to get to market? If sooner than later, outsource. 3. How capitalized are you? If undercapitalized, either outsource offshore (which runs about 20% of US rates), or bring on an equity development partner. I offer a free call to first time clients. Let's chat and I'll give you some great advice from three decades of experience.

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.

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.

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.

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!
