Dropbox product reward not cash

Make the referral reward more of the product when the product has obvious marginal value to both sender and friend.

epic tacticlow budget

Why this can grow a startup

Dropbox paid users in storage, not a generic coupon. That mattered because the reward made the product itself more useful. The friend did not arrive to a vague discount. They arrived with extra storage attached, framed as a gift from someone they knew. The sender also got more of the thing they were already using. This keeps the loop close to the product’s core value instead of turning the user into a tiny affiliate. It works best when the marginal product unit is cheap for the company and clearly valuable to the user: storage, credits, seats, usage minutes, templates, bandwidth, listings, or premium access.

Company example

Dropbox gave both the referrer and the invited friend 500MB of bonus storage, with higher caps on referral-earned space for Basic and Plus plans.

When not to use it
