This afternoon I spoke to the Stanford class on Creating Engaging Facebook Apps.
As I said at Web 2.0 expo, building big businesses online is hard work. While it isn’t hard to start an app company, especially as a single developer ($250k in revenue) or even to support a small team ($2.5m in revenue), it gets quite hard to scale revenues to $25m/yr.
Assuming a 5% daily active rate and 3 pageviews per visit, an app developer with a $0.50 RPM would need to get to 926m installs to get to $25m run rate. Compare that to the app with the most installs on Facebook – Slide’s Superwall which has around 20-21m installs. Clearly, broad reach app developers need to develop (i) multiple (ii) high engagement apps [ie higher active rates and pageviews/visit than these assumptions] (iii) across multiple social networks to be able to get close to this revenue target. (RPMs will likely be higher for companies with a direct sales force as well, so the target isn’t quite as high, but you get the point).
Under the same activity and pageview assumptions, an app developer with a $10 RPM would need 46m installs to get to $25m in revenue. Apps with endemic advertising opportunities can easily realize this level of RPM but will still need to be in multiple social networks to get to those levels of installs. It doesn’t make sense to limit your world to being a Facebook app. Social network platforms are avenues for distribution, and app developers should be taking advantage of all of them.
I also did a similar analysis for digital goods business models in the presentation. Here is a link: Stanford Facebook Class presentation
