Campaigns need to reach a minimum of 80% of their funding goal in order to succeed. If they do not reach this minimum before their campaign ends, pledgers will not be charged for their pending pledges and the campaign will not be funded.
Tips to Seed&Spark are typically non-refundable. We wouldn't refund tips if an individual campaign was unsuccessful, as tips go directly to us here at Seed&Spark, which in turn benefits all creators that use our platform.
