Reji Eapen, Very inspiring story. I recently left the corporate world took a very similar path (https://medium.com/@mukundmadhugiri/pursuing-my-passion-my-thought-process-789559d05c56#.3oe5xgjwp).
Your statement “My friends, my family, my colleagues were quick to point out that I was out of my mind. I went from a significant salary, to absolutely nothing.” absolutely resonates with me. Keep pushing!
Wishing you much success with the product and the learning that comes with it.
