StackMob, a backend service provider for mobile, is today publicly launching its mobile app platform, after having been in private beta for a good part of the year. The company, often described as a “Heroku for mobile” is a fully hosted platform that allows developers to address all the backend needs for their mobile apps including OAuth and social service integration (e.g., Twitter, Facebook), storage solutions, advertising, push notifications, analytics, API creation and more.

The company closed its Series A round of $7.5 million this spring, led by Trinity Ventures with StackMob’s existing investors, Harrison Metal and Baseline Ventures, participating. With the additional funding in tow, StackMob was able to expand to a second platform beyond iOS this October, when it launched its Android SDK. But at the time, StackMob was still in private beta testing.

Since its Series A, StackMob has seen 60% month-over-month grow in apps created using the platforms. Customers now include Fortune 50 hotels, banks and consumer products companies. StackMob has also signed up a top 20 mobile game which makes over 3 million API calls per day.

Now available publicly, StackMob is introducing two categories of pricing, with three subcategories each. The “Starter” category, meant for smaller app makers, ranges from free to $29. Pro pricing packages, meanwhile, go from $399 to $2,999. Pro packages have access to all StackMob features, including advanced REST API creation and management, push notifications, social integration, custom code and analytics. Custom packages are also available.
