Let’s review • Cut-outover half the development budget with no back-end • Outsource any server effort with MBaaS • Spend less time programming the plumbing • Spend more time making the app stand out • On-board tons of beta testers prior to launch to receive critical feedback • Generate buzz leading up to launch through influencers and free services • Bring the app to market quickly • Keep overhead to zero until reaching product/market fit • Iterate - learn, tweak, build, test
