At Uber Eats, Sonja developed and launched UberTeach, an innovative brand campaign to drive growth in suburban markets where traditional promotions had fallen short. She strategically piloted a community-centric initiative in San Diego, sponsoring a cooking competition among local high schools. The winning recipe was featured on Uber Eats, with proceeds donated to the school, effectively engaging the local community and restaurant partners. This initiative resulted in a 32% increase in local orders, a 23% lift in partner restaurant sales, and generated impactful press coverage, including 8 press stories and two instances of earned television coverage.

At Kikoff, a fintech startup specializing in credit-building products, Sonja led the CRM strategy, where she redesigned the onboarding Welcome Series without additional design resources. She partnered with Operations to identify key confusion points, strategically shifted messaging from financial jargon to value-driven product education, and conducted rigorous testing of subject lines, layouts, sequencing, and CTAs. Sonja’s approach resulted in a remarkable 300% lift in click-through rates, an 8% increase in first-month user engagement, and notably reduced early churn. Her learnings were subsequently leveraged across broader lifecycle campaigns, paid media, and automation channels.

At Uber Eats, Sonja spearheaded the go-to-market strategy for the largest enterprise partnership in the company's history: The national launch of McDonald's on the Uber Eats platform. She developed an integrated marketing strategy addressing both franchise owners (B2B) and consumers (B2C), balancing consistent branding with regional flexibility. Sonja collaborated across Sales, Legal, Product, Creative, and Customer Experience teams to unify messaging, produce tailored co-marketing collateral, and drive successful execution. Her leadership propelled McDonald's to become the #1 restaurant partner on Uber Eats, significantly increasing user acquisition, order frequency, and adoption rates across franchises nationwide.
