+## Sponsors
+
+We've now blazed way past all our goals, with a staggering £30,000 (~$50,000), meaning I'll be in a position to work on the project significantly beyond what we'd originally planned for. I owe a huge debt of gratitude to all the wonderful companies and individuals who have been backing the project so generously, and making this possible.

+
+### Platinum sponsors
+
+Our platinum sponsors have each made a hugely substantial contribution to the future development of Django REST framework, and I simply can't thank them enough.
