From Cash Back to Outcomes: Bryan Leach on Building Ibotta, Going Public, and Betting on Denver

What does it take to walk away from a prestigious legal career, build a technology company from scratch, take it public—and then reinvent the business along the way?In this episode of Signal & Noise, Brett House and Rio Longacre sit down with Bryan Leach, Founder, CEO, President & Chairman of Ibotta, for a wide-ranging conversation about entrepreneurship, commerce media, measurement, AI, and why he chose Denver as the place to build. Bryan’s path to technology was anything but conventional. After Harvard, Oxford as a Marshall Scholar, Yale Law School, a Supreme Court clerkship, and a successful career at Bartlit Beck, he realized he wanted to build something of his own. The idea that became Ibotta began on an airplane, when Bryan watched another traveler photograph receipts and started thinking about how smartphones could capture purchase data—and eventually make rebates dramatically easier for consumers. What started as a cash-back app has evolved into something much larger: the Ibotta Performance Network (IPN), which distributes digital promotions through major platforms and retailers. Today, much of Ibotta operates behind the scenes, powering offers inside experiences like Walmart and other publisher partners rather than requiring consumers to use the Ibotta app itself. The conversation goes deep on one of advertising’s hardest problems: proving outcomes. Bryan explains why a redemption isn’t enough, why incrementality matters, and how Ibotta is trying to shift CPG promotions away from impressions, clicks, and blanket discounts toward measurable incremental sales and a true cost-per-outcome model. He also explains how persistent retailer IDs and item-level purchase data make it possible to compare exposed and unexposed consumers and measure actual lift. They also dig into:Why Bryan left law even after reaching a career most people would never walk away from—and how one mentor’s decision to invest became a pivotal moment in Ibotta’s creation.How Ibotta grew from roughly 2 million to 20.9 million redeemers, with much of that growth coming through third-party publishers. Why Bryan believes promotions should increasingly be treated as an always-on performance channel, with spending governed by incremental economics rather than fixed annual budgets. How AI is already changing Ibotta’s product, software development, measurement capabilities, and internal workflows.The transition from private company to public company—and the lessons of building one of Colorado’s landmark technology companies.Why Bryan sees Denver’s culture, talent base, quality of life, and civic accessibility as competitive advantages for founders. It’s a conversation about much more than coupons or cash back. It’s about transforming promotions from a century-old marketing tactic into a measurable growth engine—and what Bryan learned from taking Ibotta from an idea to a public technology company along the way.#SignalAndNoise #Ibotta #BryanLeach #CommerceMedia #RetailMedia #CPG #PerformanceMarketing #AdTech #MarTech #Incrementality #MarketingMeasurement #DigitalPromotions #RetailTech #CustomerData #AI #ArtificialIntelligence #Entrepreneurship #Founders #Startups #DenverTech #ColoradoTech #IPO #BusinessLeadership #Innovation #Marketing #Advertising #ConsumerBehavior #FutureOfCommerce
