Marks speaks with Anthoney Lacavara how Magento compliments Amazon and it's various offerings.
Magento was spun out of eBay more than 18 months ago and now commands $50 Billion in transactions, making it the largest SMB commerce platform that is focused 100% on commerce. Mark points out that other platforms have been gobbled up by ERP's or CRM's. Magento remains independant and flexible.
Magento is able to compete against players like Amazon simply because of it's flexibility and ability to update the entire codebase on each instance. This is something that other SaaS platforms can not do.
