Every user can invite up to 100 people who each get $10 if they sign up (thats a max of $1000 for 100 users). Hope that clarifies it a bit :)

Even PayPal with millions in funding only gave away $5/referral. $150,000 there brings you 30,000 users, but "SwipeGood is giving every user who enrolls on the service $1000 that they can give away to charity." That's 150 users or am I missing something?

It looks like $10/referral up to 100 referrals. If they make $20/user/mo this is a no brainer.

I think they only get 5% of that $20/user/month. That being said, here are two options for how to use $150,000:

1. Hire an engineer for a year

2. Sign up 15,000 users and generate $15,000/month in revenue. Hire an engineer permanently and net an extra $30,000/year in profit.

I know which I'd choose.
