Not really sure what the financial situation is but it kinda sounds like they hired you as a contractor or they are just hanger-ons and not really business partners among equals. Lots of people will happily take a big cut of your business without contributing anything.
And I don't know building consumer... but you should get users/customers & get feedback back from them. Thinking you need to pitch to VC's with the perfect deck or app is a trap, what you need to do is build a product and business.
