Idea
Bidding-Aware Retrieval platform improves ad traffic allocation accuracy for online advertisers and ad tech platforms.
Research Paper
Core Innovation
This paper introduces Bidding-Aware Retrieval (BAR), a method that incorporates bid values directly into the retrieval stage scoring to ensure consistency with ranking stages. It uses monotonicity-constrained learning and multi-task distillation to maintain bid influence and employs asynchronous near-line inference for real-time embedding updates. Additionally, a task-attentive refinement module disentangles user interest from commercial signals, improving retrieval relevance and revenue.
Market Size (TAM)
$20–50B TAM, $2–10B SAM; assumption: global online advertising spend and demand for improved ad delivery efficiency.
Potential Customers & Pain Points

Research Paper Overview
Bidding-Aware Retrieval for Multi-Stage Consistency in Online Advertising
Summary
This paper addresses inconsistencies in online advertising cascaded architectures caused by auto-bidding strategies lacking real-time bid access in retrieval stages. It proposes Bidding-Aware Retrieval (BAR), which integrates bid values into retrieval scoring using monotonicity-constrained learning, multi-task distillation, and asynchronous near-line inference for real-time embedding updates. A task-attentive refinement module separates user interest from commercial signals. Deployed at Alibaba, BAR improved platform revenue by 4.32% and impressions by 22.2%.
