For everyone who wants to develop applications within the Facebook platform. Facebook has launched a fund from where developers can apply for funding of their Facebook projects.

This is the standard answer to any enquiries about the fund program that is sent to the following address: fbfund@facebook.com

"Thank you for your inquiry about the fbFund grant program, and for your
support of the Facebook Platform. Our goal for this program is to
encourage as many developers as possible to write innovative and
engaging new applications on top of Facebook Platform. Additionally, we
hope to enable an even broader class of developers to become
entrepreneurs by giving you the financial resources necessary to pursue
a new venture that relies on Facebook Platform.

It has become clear that we will receive proposals which contain similar
or even identical ideas. As a result, and in order to protect other
developers and us from claims that we or anyone else copied material
without the creator's permission, unless we agree otherwise in writing,
we can't promise that any materials or information you submit here will
be kept confidential, or specifically that we or others might not
develop similar or identical products or services.

To make sure that everyone understands the conditions of submitting a
grant application, we will not review any materials you have sent via
email, and any materials you may have sent have been deleted. If you
would like to submit an application for an fbFund grant or require more
information, please see our website and grant application submission
form at http://www.facebook.com/developers/fbfund.php. We apologize for
the inconvenience, and hope the online information and submission form
will help you develop and structure your proposal. We are accepting
applications from around the world.

Again, we are very excited to be offering this program and wish you the
best of luck whether or not you are an fbFund grant recipient. We can
only give a limited number of grants and not getting one does not mean
that we don't believe in your application nor that it can't be
successful - it simply means that we have a limited amount of resources
and weren't able to give money during this cycle to you. You are
welcome to apply as many times as you like as each funding cycle
represents a new opportunity to receive a grant.

More information is available at
http://www.facebook.com/developers/fbfund.php.

Thank you for your patience -- we apologize for the delay in this
response. We've seen a tremendous response to fbFund, and look forward
to reviewing great proposals.

Cheers,
the fbFund team"
