At Tarro, we empower small brick-and-mortar restaurants by relieving them of the operational burdens of running their business. Our multi-product ecosystem provides AI-powered order taking, delivery enablement, and marketing solutions, creating a seamless connection between restaurants and their customers. By combining cutting-edge technology with a dedicated team, we tackle the real-world challenges faced by small business owners. We are customer-obsessed, working backwards from their needs to ensure their success is our success. The U.S. restaurant industry represents a $1 trillion total addressable market (TAM), yet small restaurants often lack access to affordable technology. While large chains benefit from expensive tech, we believe small restaurant owners deserve the same advantages at a fraction of the cost. With the trust of thousands of restaurants, we're now serving tens of million of customers. We’re proud to have been named one of Built In’s top companies to work for in 2024.
