Since I just got hired by FundRazr, I won't comment on my competition, but I'll tell you a bit more about us:
We're partnered with PayPal and we use them to process all payments, plus we actually helped PayPal develop the Send Money app that they use on Facebook. We're also one of the first 8 companies accredited in the CAPS crowdfunding standards initiative (http://www.crowdsourcing.org/caps
), and our CEO, +Daryl Hatton
, is a CAPS council member.
Like I said, I just got hired so this is info that I've gathered as part of my job research, but I'll be able to tell you more about the company as I learn it. :)
