Hi Rachel, TWIST has an excellent interview with James Beshara, the CEO of Tilt. Their API powered the Navdy campaign - http://thisweekinstartups.com/james-beshara-tilt/. There's some amazing insight in that interview and he goes into some of the advantages.
I currently consult on crowdfunding campaigns, and the answer to what's the right venue always comes down to fit. Meaning, which platform will perfectly frame your product? If you're selling something that inherently has an artistic value proposition, that an eager hipster & early-adopter can see fitting into their life, Kickstarter is likely right. If it's a new mobile phone with an open-source technology that really sells itself, then Indiegogo can be a great option. These examples are of course stereotyping a bit, but they illustrate the point.
A DIY pre-selling campaign really makes sense if you need a really tight look and feel around the product and already have marketing firepower. For Navdy, this made a ton of sense.
The other DIY advantage the article doesn't mention is being able to track analytics in a comprehensive way. For instance, for the Kabaccha Shoes
campaign I'm currently working with, we have paid FB ads running to the Kickstarter page itself, but measuring conversions is somewhat of a black box. If you set up a campaign using the Tilt API, then you could actually embed scripts to track EVERYTHING. And this is hugely valuable.
