nope. whie its true facebook ads are the reason behind not only Ravean but most crowdfunding project success, its not as easy as targeting those who share similar interests with Indiegogo, Kickstarter and Gofundme pages.
whats true is the idea of crowdfunding, or what some refer as "pre-order" applies to everyone with everyone who have buying power. for example, my research on tech based project before, the best fb ads setting was to aim for those interested with uncrate, coolmaterial etc. aiming those who interested with the idea of crowdfunding itself doesnt work for you.
you need to aim those who are interested in outdoor sports product (as per your niche) like those who share similar interest with any outdoor activity. search googles for the most famous sites for your niche, line them up, put it in your fb settings and try to run for united states only.
