Joe Grimes

CEO and Director

Joe Grimes

Joseph Grimes has served as the CEO and Director of Tribal Rides since 2016. I am an accomplished executive and serial entrepreneur with a 25 year track record of success who drives technology based business opportunities from conception through implementation. Experienced in developing high level go- to-market strategies, securing financing, building and executing multi-dimensional operation plans, and, directing and motivating dedicated, goal-oriented teams to function in a coordinated and systematic fashion and accomplish stated business objectives. I graduated from the University of California, Santa Barbara, with a BA in Economics and Environmental Studies and also with a graduate degree focusing on Operations Research and Logistics, with his thesis in deriving “Near-Optimal solutions” to NP-Complete transportation problems by leveraging heuristic solution techniques. During my 12 year tenure at ISERA Group, which I co-founded and was President, I managed 5 teams of software system designers tasked with developing sophisticated Decision Support Software Systems for commercial, military and government sectors for the Department of Defense and National Science Foundation (NSF). I successfully negotiated and managed sophisticated US Government contracts of $20 million including a Phase 3: 5-year Indefinite Quantity/Indefinite Delivery Contract (IQ/IDC) with U.S. Navy (sole source) resulting in five commercial software systems, which improved system through-put, reduced costs, increased overall system capacity, were easy-to-use, and in the case of the Deployment Planner, saved countless lives. From 2015-2018, Joe served as the VP of Sales at Draker Energy, moving over to full time Business Development at Trimart in June of 2018 (his primary role.). He spends 30 hours weekly on Tribal Rides.
