Abstract: Offers are presented to one or more users of a crowdfunding platform based upon information gathered from multiple users' activities across one or more campaigns. An offer may be provided to the fundraiser based on a campaign category, a campaign keyword, a campaign profile, offer profile or user activity history. A user profile may be used to determine an offer by comparing the profile to attributes of one or more offers. The selected offer can be presented to users such as funders, fundraisers and others.

Abstract: A crowdfunding platform can receive an indication that an entity has completed an action. Examples of an entity include a funder, a campaign account owner, a third party and a combination thereof. Examples of actions include making a purchase, subscribing to a service, joining an entity's social network, etc. Upon receiving the indication, an account (e.g., a crowdfund account such as a funder and/or campaign account) can be credited with a value that can correspond to the completion of the action. Value can be transferred from an external account (such as travel rewards program, an external virtual currency account, etc.) to a crowdfund account and vice versa. If the transferor account is denominated in a different unit of value than the transferee account, an exchange rate can be determined and applied to the transaction.
