Crowdfunding platform tips?

I’m vol­un­teer­ing for a young EA-al­igned non­profit and try­ing to put to­gether a crowd­fund­ing cam­paign. For this cam­paign, we’d like to pick a plat­form that’s ap­pro­pri­ate for a global health char­ity try­ing to ex­pand its net­work and at­tract donors. Ease of use, high visi­bil­ity and match­ing funds op­por­tu­ni­ties are also pri­ori­ties. We hope to reach donors and ac­cept dona­tions from around the world—es­pe­cially UK, US and In­dia. There are many fish in this sea, so it’s a lit­tle hard to nar­row our search based on limited in­for­ma­tion.

Does any­one out there have ex­pe­rience (pos­i­tive or nega­tive) with a par­tic­u­lar plat­form that you’d care to share? What have your ex­pe­riences been? Any rea­sons why you would recom­mend a cer­tain plat­form? If any­one has done any kind of stud­ies on any of these plat­forms, that would also be great to know.
