Alexandra Botez and Ruben Mayer-Hirshfeld created the "SuperFan" app while they were students at Stanford University. Now, the recent graduates are working full-time on developing the software that allows influencers and celebrities to categorize fan messages, and create personalized messages with machine learning. The co-founders recently pitched their idea on Apple's "Planet of the Apps." Lightspeed Venture Partners made a $250,000 investment in SuperFan.
