Idea
Semantic search platform delivering sub-second queries over trillion-scale text corpora for faster, scalable data discovery.
Research Paper
Core Innovation
This paper introduces SoftMatcha 2, which combines suffix arrays with a disk-aware design and dynamic corpus-aware pruning to enable fast, soft pattern matching over trillion-token corpora. It suppresses exponential search space growth by leveraging natural language statistics, achieving significantly lower latency than prior methods like infini-gram and the original SoftMatcha.
Why It Matters
Searching massive text corpora quickly and flexibly is critical for research, compliance, and content verification. SoftMatcha 2 reduces search latency drastically while handling semantic variations, enabling real-time insights and contamination detection at scales previously impractical. This transforms workflows by making large-scale text analysis accessible and efficient across industries.
Market Size (TAM)
$10–20B TAM for large-scale semantic search and text analytics; $2–5B SAM from research institutions, legal/compliance, and AI training data providers. Driven by exponential data growth and demand for real-time, flexible search.
