Can i start a startup business in U.S if I'm not living in U.S and I'm also not an american citizen?

One word: Royalties This means you generate the idea and develop it enough to look interesting to a larger company who would be willing to pay you a royalty for your idea. This happens all the time. Rock stars, authors and scientists routinely license their creative ideas to other companies who pay them a royalty. Anyone can do it. Your business, therefore, would be a think tank. You (and your team, if you have one) would consider the world's problems, see what kinds of companies are trying to solve those problems, and then develop compelling solutions that they can license from you. You have to be able to sell your idea and develop a nice presentation, a little market research and an understanding of basic trademark and patent law. The nice thing about doing this is that if you develop enough cool ideas you will have royalties coming in from a lot of different sources, this creates a stable, passive revenue stream that requires little or no work to maintain. Start in your spare time and plan on the process taking 3-5 years. Set a goal to have a few products in the market that provide enough revenue (royalties) to cover your basic living expenses. Then you can quit your day job and dedicate more time and increase the momentum. A good idea business should have dozens, if not hundreds of license contracts generating royalties. It's possible to pull this off. And it is a fun job (I'm speaking from experience).

Most of the earnings come from the people you are in contact with. The platform is not that big at the moment but it can be earned. My recommendation is to create content on your private page web, facebook, instagram ... and leave a clarity link through your work. If you need extra help call me for 15 minutes.

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.

10% of the total monthly sales churning on an absolute basis is near fatal. That means that within 5 months, you have 50% absolute churn per year, which reveals fundamental flaws with the service itself. Anything above small single digit churn is telling you and your team that customers are not seeing enough value in your product. I'd start by doing as many exit interviews as you can with those that have churned out, including, offers to reengage at a lower price-point while you fix the issues that matter to them. Happy to talk through this in more detail in a call.

It stands for allowing someone to continue doing or use something that is normally no longer permitted (due to changing regulations, internal rules etc.)
