Check out the Draknek New Voices Grant
Draknek has been doing grants for developers who make "thinky" puzzle games for a little while now. If you are a developer from an underrepresented background who makes puzzle games, check out this page - you have until September 28th to apply for one of five $15,000 USD grants.
The page also has a list of the project selections they made last year.
If you have money to splash around and want to help with the grants yourself, there's information on this page about making a donation towards their costs or sponsoring a grant in a more substantial way.
