Having just had a successful IndieGoGo campaign (which was written up on Forbes Tech - see http://bit.ly/ForbesT410K) - after Kickstarter turned us down (I doubt they grokked what we were doing) I say GoGoGo!
Actually I think Kickstarter is excellent and not losing track. I wrote an article with accompanying case studies on how best to use these sites http://suitcaseentrepreneur.com/marketingandsales/how-to-create-a-kick-ass-crowdfunding-campaign-and-make-your-dreams-come-true/
Depends what you are looking for and where you are based. If you are based in the Northern Europe, Invesdor is the leader in open equity-based crowdfunding services.
I think IndieGoGo is now better than Kickstarter, after the latest KS policy changes.
Kickstarter more powerful tool for funding, of course policies IndieGoGo much better with flexible rates. But i prefer Kickstarter
Kickstarter... by a longshoot.
I'm sure that if you asked 10 people on the street they would be more familiar with Kickstarter versus Indiegogo.
Honestly, if you look at App.net and https://lockitron.com ... Kickstarter is loosing track ... and fast.
And Kickstarter started loosing the moment it did not allow projects from outside US. Sounds kinda hypocritical if you think ... they accept donors from all over the world, but only for US projects.
I have contacts that DO NOT want to have a campaign on Kickstarter. However, they were successful on IndieGoGo.
The platform is irrelevant, crowdfunding campaigns are totally under the control of the project owner since funding is derived directly from promotional efforts using social media. Even on Kickstarter, at least 80% of all funding for a project comes from promotional activities by the creator. The balance comes from Kickstarter traffic. One downside of Kickstarter is they follow the "all or nothing" funding model, so if you don't reach your goal amount, you get zero! Check out - www.fundageek.com which does not follow "all or nothing."
There are 100s of crowdfunding platforms out there. Kickstarter and Indiegogo are the more popular once but some other once could be better if you are in a specific industry. My company crowdsunite.com , aims to categorizing all of these platforms so that you can easily compare them.
When looking to raise money from the crowd, Direct Public Offerings are legal and being used every day. They are flexible and can be used in multiple structures. They are too often overlooked as alternatives to Angel or VC funding or Bank Loans.
We are seeing a big surge in their use at our firm.
I think Kickstarter is also going ahead with numbers. Check out this feature to have an idea how: http://startups.fm/2013/09/04/kickstarter-vs-indiegogo-by-the-numbers.html
