Tinysponsor is the world’s largest marketplace for sponsorships. A service offered on Tinysponsor is called a Package - think of it as buying and selling sponsored content the way you'd buy or sell anything else online.
Signing up to Tinysponsor is free and can be done here. Only registered users may buy and sell on Tinysponsor.
After successfully signing up, you’ll want to check your registration email for the activation link provided in a welcome email. If you created an account some time ago, the link may not work. You can request a new link while you’re logged in to your account, even if it's not activated yet, or ask Customer Support for assistance.
You can browse sponsorship types or use the search to find a Package you wish to purchase. Once you find a Package, read through the description and deliverables of the services offered and view the Creators work samples, if available. If you would like to make a purchase, just add it to cart, and proceed to checkout. You can pay for the service using a credit card.
As a creator, you can offer services for Sponsors to purchase, the same way you'd offer an item on any ecommerce site (think Etsy). Creators set their own prices for the Packages that they offer on the platform. All Packages are free to post, but please note that Tinysponsor charges 15% marketplace fee + 2.9% credit card processing fee when your Package is purchased by a Sponsor. Be sure to consider this when setting your price.
