Product Development expenses also scaled, falling from 9.3% of revenue in Q1’25 to 7.9% in Q1’26. This reflects the deceleration in headcount growth, and the increasing use of AI among our engineers. Gains in productivity mean that we intend to keep engineer headcount broadly stable in 2026

Productivity gains across our technology teams are among the most tangible results of our AI investment. Headcount grew 8% YoY in Q1’26 – a carryover effect of 2025 hiring – but productivity KPIs are growing 7-10x faster. Many of our most senior engineers that were previously spending most of their time reviewing code are now also building code because of the productivity gains enabled by AI tools. Rollbacks – code that is returned to its developer due to errors – are materially lower YoY.

We expect this leverage to be partially offset by the ramp up in our use of third-party AI models. This reflects a deliberate choice to prioritize company-wide adoption over cost optimization at this stage. This investment is contributing to cost efficiency across many other expense lines (customer service, for example) as well as helping us to generate incremental revenue (in Acquiring and Advertising, for example).

We rolled out our first AI-powered search experience in our marketplace in Q1’26, shifting the architecture away from keywords and rebuilding it around LLMs. In Brazil and Mexico, the improvement in product relevance led to uplifts in conversion and click-through-rate for sponsored listings, both of which represent incremental revenue. These are early results, which we believe have the potential to transform how our customers search and discover products on our platform.
