Should I offer my beta B2B service for free for a major established company which is probably going bankrupt in one year or less?

Find apps that are B2B and go to the review sections. Specifically going to Google's play or Chrome store and look at reviews and follow them to Google+ to engage. I took that same angle for B2C app I was building last year. Check it out. http://blendah.com/post/37331434653/lean-startup-hack

For pure B2B, nothing beats the free and fee offerings at http://www.marketingprofs.com/

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.

Start by getting a doctor to 'sponsor' you - to recommend it to their patients. Give them a few for free so their patients can try it out - which will get the physician sold on it. Meanwhile, also start reaching out to the right people in the appropriate insurance companies through LinkedIn and via email. You may also want to connect with people who have been in Insurance - like Jeff, Daniel, Craig, or Liran here: https://clarity.fm/search/insurance When you reach out to executives in insurance, keep it personal, and tell them you are looking for their advice. I have a 12 step system to walk you through the sales process once you get a call lined up, but to get you started you could read The Little Red Book of Selling (quick read) or The New Strategic Selling (dense but invaluable). SNAP Selling is good too. Remember, this is all about relationships, so start with personal. InMails recently changed to make it easy for you to keep costs down for outreach. As long as you get a high response rate, your cost of $10 per unanswered InMail will go a long way. If you can't use InMails, try sending samples with testimonials and call them to discuss the day after you expect them to receive it. Use FedEx sign on delivery to increase the chance it gets to them instead of a mail room or secretary.

As your targets are SME companies with 3 or more developers you can use LinkedIn premium search for finding the list of top executives of the companies and send them in-mails for partnership! Another great source for you could be outsourcing websites where US development companies are represented and do testing for their clients periodically for various projects! Please call for more detailed information of the best B2B sources for you! I have got also some availability to the actual lead generation job for you with a reasonable hourly rate. I have been working as a sales manager in this industry for over 4 years and have got large databases of B2B clients that you will be interested in!
