Well, the assumption is that big companies are not in the business of developing their own wallets. They may be responsive to an opportunity to monetize their existing user base with a turn-key product like our exchange-in-a-box.
So the deal you negotiate is (after studying their business model) some variation on this:
"Our company will provide a service you can link to from your web site that will gradually teach your customers about our features and return you a revenue stream."
That service is what signs up the customers and distributes the revenue stream to three parties according to some negotiated deal.
X% goes to the Big Company as a new revenue stream they didn't have to pay for.
Y% goes to the developer of the drop in app for providing and integrating the software.
Z% goes to the referrer for negotiating the deal and providing the training to make happy quality users.
Sure, a Big Company could theoretically later come along and develop their own app, but they are not in that business. You might as well worry about them developing their own advertising systems and shopping carts instead of integrating the best of breed.
Here's a killer product you might offer:
If they hold their "Amazon Coupon Tokens" they earn "interest" in the form of discounts at Amazon. The 3% discount can be made to look like 3% interest. So they can sell Amazon Discount Tokens that earn a "yield" and can be spent later! The longer you hold them, the better your discount.
Instant Amazon savings account that pays more than your local bank!
No need to even mention that it's Powered by BitShares. No need for Amazon customers to see the full exchange until later when they can follow a funnel into what else they can do with their Amazon Points.
Lots of opportunities for entrepreneurs to build on the BitShares platform in new and novel ways.
