I'm a product manager that oversees several hundred apps over roughly 25 stores on 8 platforms (Android, iOS, BlackBerry/QNX Windows, Symbian, Bada, Brew, J2ME).<p>We are do a steady 2.5 million in sales per year, aiming for 4m next year.<p>The problem is that startups in the Valley are extremely narrow minded and aesthetically snobbish in their mobile approach.<p>1) There are 1 billion feature phone users around the world who have perfectly usable app stores.<p>2) You need to launch in more languages than just english, and on more app stores than just the US market -- Chinese, Hindi, Spanish and Portuguese at a minimum.<p>3) Apps that are not SAAS are throw away, impulse buys. They should be developed with that in mind.<p>4) Apps have a short lifespan and sell based on timeliness.<p>5) If you want guaranteed profit in mobile, build mobile extensions for established brands, don't try to build the next Angry Birds or Apple App clone.<p>6) Design matters, but not that much. Touch interface has made UI far more visceral, but the sale happens long before the user judges the design<p>7) IAP -- its icky but it works<p>8) Try lots of stuff rapidly and fail fast. 2-3 month cycles. You can get up to about 10 apps a month if you have a larger team and a good process.<p>Finally, this is nothing like 1999. Companies were failing with no product, spending 1 year + and not even launching. There were late round fundings for companies that literally had products that were figments of their imagination.<p>Now two guys in their garage can build a hit app with two macs and no funding what-so-ever. Don't confuse a highly active, easy to penetrate market with a bubble.
