I have an idea that would interest LinkedIn , Facebook and Google a social app, I do not have the skills ,resources to build the solutions myself and am afraid to tell them the idea they may not need me anymore. What should I do ?
1) I would suggest you start working on building the skills required to build it or find a co founder who has the skill.
2) approaching a big company as Facebook or google with an NDA expecting them to sign is not the most effective way. You'll have a better chance building the right team and a prototype (some times a prototype isn't even required) but I'll emphasise building the right team. Companies invest in people not ideas.
3) carry out a market survey to back your idea. Companies will be more likely to pay attention if you have actual data to back up product. It's one thing to say you have a good idea it's another for it to be a product people will use. So get out there and get feedback
4) BUSINESS MODEL!!. Pay attention to this as this is the veins for your company. It doesn't have to be bullet proof as the social space is dynamic and your business model will change but it should be scalable.
5) People are under this notion that if I have an Idea I should keep it to my self for the fear of it being stolen. its the most counterproducti approach to entrepreneurship. The probability that you're the only one in your country talkless of the world working on your idea is little to none: from you NDA notion to big companies I'm guessing that you're not sharing your idea openly. I would suggest you share your ideas and it's the only way to get feedback.
Your best chance is getting a co founder and working on initial designs you can use to show case what your idea could be.
In working with startups, I have seen a lot of founders labor under the false impression that they had an original idea. Have you searched sites like Crunchbase and Angel to see if there are already people working on your idea? If there are others working on it, it doesn't mean you can't do it also, but it does mean that it is likely that the big social networks are at least already aware of the idea.
The second thing an idea in the hands of a person that can't execute on it, is not worth much. At a minimum, you will need to find a co-founder or resource who can at least help you build enough of a solution to validate the idea. A lot of "good ideas" break down when put in front of potential users. If you can find someone to help you develop an MVP, you can at least prove that the idea has merit while showing some of your resourcefulness.
If your early work shows signs of product/market fit and validation, then you have something to start to recruit with. Build something before you try to take anything to a big company. If you have not made real progress in showing that the company/idea has value, you won't be able to get them to pay anything.
Validate the market
Get some customers/users/traction
Then decide if you still want to approach a big company or build it yourself.
First of all get a intellectual property patent if it falls under criteria
then approach company with a written communication and sign NC & NDA with the appropriate authority.
Just PM them and let it go.
write short essay of what you wanna do like a 3 pager and send to them
Start with small companies ....have some experience ....find out your negative point and work on them.....and if u feel confident to peach to big companies go for it .....this is the right way of practicing business.....
If after this you have any doubt abt it then search the history of Google or face book...very body started small but now they the giants
First of all, start with some good knowledge about starting a venture. It shows you what options you already have. This position is the best for you at this stage.
Sign NDA(Non Disclosure Agreement) with resources or company.
The way I have approached this in the past is to connect via linkedin with other product people in the target company(s) and start a dialog about them without revealing to much about my idea. most of my relationships with large companies have happened because I got to know someone there and then moved laterally in the org until they trust me, then I ask for an intro to a higher position exec.
