The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at the Trope Launch Pad.

Closest thing right now is Pre-Order Bonus. Since crowdfunding is done pre-release, your pre-order bonus is just proportional to the amount extra you contribute to the crowdfund.

Is there a trope/trivia item out there for people who crowdfund a work getting special perks? It could be anything from early access or name in the credits to full-on exclusive content.
