Product thinking at scale.

Growth Acquisition Retention

Isadora Serpa is a senior product leader with a track record of building high-impact digital products at scale — from iFood, Latin America's largest food delivery platform, to AB InBev's Zé Delivery, where she led the consumer loyalty strategy that acquired 3 million users in its first year.

She specialises in growth, loyalty ecosystems and rewards platforms — designing the behavioral mechanics and product systems that drive retention, engagement and revenue at consumer scale.

She also writes on Substack about product strategy and leadership for practitioners building complex consumer products.

Consumer Loyalty Ecosystem

Product vision and strategy for Zé Delivery's loyalty platform
AB InBev Zé Delivery

Zé Delivery lacked a retention mechanism — no structural way to increase purchase frequency or consumer lifetime value.

  • Defined and led the end-to-end & product strategy
  • Integrated the loyalty program across AB InBev and partner ecosystems.
  • Structured the rewards program: points system and rewards catalog.

Built loyalty into a strategic growth engine for AB InBev — delivering high-value benefits and fueling retention at scale.

3 million Users acquired — year one
