While platforms such as Kickstarter and Indiegogo do not offer this option themselves, I have seen a lot of cases where creators offer this as a reward tier option and/or create one for a backer upon request.For example, The 1 Million Redwoods Kickstarter campaign (which I backed!), offered a reward tier called u201cSeed to Treeu201d which reads:u201cWe will plant a tree in your name, or in honor of a loved one of your choosing. You will also receive a digital Certificate of Stewardship, and video updates.u201dAnd personally, I had a few requests during my brother and Iu2019s #SavePepe Kickstarter campaign to have something to signify a gift before our product was manufactured. We just handled these on a per-customer request basis and it only amounted to a handful of backers with the request.And Kyle is correct, a platform pre-sale (or fulfillment) platform could handle this if they have a digital delivery system as part of their service. Lucky for me, BackerKit has a super easy digital reward delivery system as part of their service. I was able to create a PDF and deliver it to anyone with the request.Thanks for the question.
