I have an idea for a new social networking app and from researching and reading posts all around the internet I've come to the conclusion that this will cost upwards of $100k to develop to launch. Somewhere up with Tindr or a Snapchat in terms of complexity and functionality. Lots of features, lots of APIs, lots of code. It's an idea and a function that I am extremely passionate about but I do not know how I would go about getting the funding to do it. As you would expect, I entirely believe that this app could quickly gain a large userbase and generate significant revenue on a daily basis (simply because what the app helps people do and the social nature of what it can do) I've thought about several different options: 1. Kickstarter/Crowdfunding: Kickstarter was the first glimmer of hope I had. It's the type of app that would get great support on a crowdfunding site because of it's power to connect people, however in researching US patent laws I've determined my mobile application would not be eligible for patent protection. I'm afraid that if I crowdfund it and the campaign starts getting noticed some big player could swoop in and develop and launch it themselves. 2. Waiting 2-3 years until I have the funds to cover the development: Sadly this is my most likely course of action. We all know that the mobile app game is extremely fast paced. 2-3 years from now is an eternity, and there's no guarantee that I'll even manage to get the money in that time. Without sounding braggadocios or pretentious, this app idea will be built by someone else if I don't do it. I feel that if I don't start acting now then someone will get this idea sooner than later. It's somewhat of the next logical progression for a future social network platform. Plus 2-3 years from now the mobile app marketplace could be entirely different. The entire landscape could change. 3. Selling the idea: The thought has crossed my mind that if I sit down and create a complete and indepth white paper/blueprint with everything fully detailed I may be able to sell it. But for what? Probably not even a fraction of what it would be worth after launch. My research into selling app ideas hasn't turned up with much information. In my head though I'm thinking best case scenario someone comes along who understands the scope and grand vision of my application and buys it for $1k or something miniscule. My questions: has anyone funded an expensive app development? How did you go about it? Did you self-fund? Is there a market for mobile application ideas? Are there any known devs out there that develop for a fraction of the cost in exchange for a large percentage of the future earnings?
