Pitching an idea to an existing company for their own products
I've got an idea which would work as a standalone product, but would work best with an appservice such as Uber (taxi service company)bolting it on to their existing offering. Assuming I have no contacts within the company (happy to cold call), how would you go about getting the opportunity to pitch it to them. I dont care much for making vast sums of money, just a fair deal (and have no delusions about how low for me, fair could be), and more importantly for me, seeing my idea work and make a difference to the world. I am gainfully employed by one of the big 4, in london, and have no desire to leave my current role, and building this on my own isn't realistic, so anything is better than nothing.
current plan is either to walk into their London office and try my luck there, or harass someone on linkedin until I get a bite.
Anyone can think of anything better, let me know.
thanks in advance.
