What software (API, plugin, etc.) should I use for my website to assist in complying with COPPA policies?

You should retain a lawyer, or another qualified individual, to act as the third party designee for the corporation (if you do not have a partner or co-owner who is a US citizen). The designee should prepare Form SS-4 (Application for Employer Identification Number) and Form 8821 (Tax Information Authorization) for the corporation’s president to sign and return.

Non-disclosure agreements are very common. Know that a non-disclosure agreement goes both ways as well. A contract agreement should also protects you from the other party disclosing any trade secrets or know-hows that they may learn from working with you.

I do not believe you should incorporate your company yet as there is a chance you will scrap the idea or iterate on the assumptions after analysis. I suggest you run your initial testing on a very minimal MVP to see if there is interest. I would go further in saying that you should not even allow people to pay only have them click on the payment option because at that point you know that it would be a conversion. The ONLY thing you are proving with an MVP is validation of an idea. Only make the mousetrap front end and see if you can drive users to where you want and stop. Even if you frustrate some people, it was worth it as you now know for sure people will buy or do what it is you wanted. Schedule a call with me to find out more. God knows I have done this enough times. Good luck Josh

I've discussed ideas with hundreds of startups, I've been involved in about a dozen startups, my business is at $1M+ revenue. The bad news is, there is no good way to protect ideas. The good news is, in the vast majority of cases you don't really need to. If you're talking to people about your idea, you could ask them to sign an NDA ("Non Disclosure Agreement"), but NDAs are notoriously hard to enforce, and a lot of experienced startup people wouldn't sign them. For example, if you asked me to sign an NDA before we discussed your Idea, I'd tell you "thanks, but no thanks". This is probably the right place though to give the FriendDA an honorable mention: http://friendda.org/. Generally, I'd like to encourage you to share your Ideas freely. Even though telling people an idea is not completely without risk, generally the rewards from open discussions greatly outweigh the risks. Most startups fail because they build something nobody wants. Talking to people early, especially people who are the intended users/customers for your idea can be a great way to protect yourself from that risk, which is considerably higher than the risk of someone taking off with your idea. Another general note, is that while ideas matter, I would generally advise you to get into startup for which you can generate a lot of value beyond the idea. One indicator for a good match between a founder and a startup is the answer to the question: "why is that founder uniquely positioned to execute the idea well". The best way to protect yourself from competition is to build a product that other people would have a hard time building, even if they had 'the idea'. These are usually startups which contain lots of hard challenges on the way from the idea to the business, and if you can convincingly explain why you can probably solve those challenges while others would have a hard time, you're on the right path. If you have any further questions, I'd be happy to set up a call. Good luck.

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!
