Rangarajan and four others—Satyam Kandula, Lakshman Kakkirala, Giridhar Murthy, and Aditya Kulkarni—started Little Eye Labs based on the discovery made at developer conferences: Android enthusiasts lack a tool to diagnose apps or test their performance. They built the product in nine months and found an investor, before slowly winning developers over locally, then in London, then Silicon Valley—before Facebook spotted Little Eye and bought it.
