Ask HN: Suggestions for revenue deal with a bigger startup

Hi fellow HNers,

We have a startup with no traction at all. We are having difficulty acquiring users on the consumer side of our service.

However, a large startup wants to use our service. They have millions of users which would give us instant traction.

I need some suggestions on a revenue model for them white-labeling our service.

I really don't want to charge them a monthly fee because it might scare them away. However, I'm concerned that if a large number of their users use our service, it may cost us a lot of money to support them.

All I could think of is to have 50/50 split on advertising.

Any other ideas?

Thanks!
