Koch Disruptive Technologies, a venture capital firm, led a series D funding round in Ibotta, a free cash back rewards and payments app. Financial terms were not disclosed. "While we've reached the point of critical mass awareness when it comes to paying with our phones, there's still one piece missing on the path to true adoption: rewards. Through a shared vision with KDT and our expertise in rewards and consumer psychology, we are best-positioned to transform the emerging $100tn global payments market. The excitement of cash rewards will be the flash point in changing consumer behavior and driving adoption of new forms of mobile payments worldwide," Bryan Leach, Ibotta Founder and CEO.
