Pete and I spent a day at The Vault SF interviewing some of the most promising up and coming startups of Silicon Valley. John Singleton, COO and cofounder of Watchful.io is a charismatic guy that comes across as fearless and fun. He has the entrepreneurial spirit through and through and shared his non linear path from studying biotech at the University of Texas, to founding a Fin-tech startup to moving to India and suffering the blows of startup failure.
