The BMCC recommends the use of the business model canvas developed by Alexander Osterwalder & Yves Pigneur. The video below describes how to use the canvas and here is a link to a digital version of the canvas that you can use. You can also download a printable copy of the canvas here. Also check out the StartupToolKit.com for additional business model canvas resources.
To see how to use the canvas in a presentation view the video of Owlet Baby Monitors, the 2013 IBMC champion.
