Boston's startup scene has given birth to several startup accelerator programs over the years, ranging from MassChallenge to Techstars. Now, a new kind of program is debuting — one that's focused on helping consumer-focused product companies launch and run successful crowdfunding campaigns. Boston-based Fortify Accelerator, co-founded by Boston entrepreneur and crowdfunding consultant Trevor Collins, is an eight-week intensive program aimed at helping companies run crowdfunding campaigns on Kickstarter, Indiegogo and Tilt.
