It sustained a 20% month over month growth in paid subscribers, and was one of Business Insider's top startups of 2011.

While always an active code contributor, much of my time was spent working small groups through challenges, identifying bottlenecks, and setting milestones. Projects included growth drivers like internal funnel tracking, A/B testing frameworks, and social analytics tools.
