Could you build this?
No Moss is custom, low-latency search infrastructure built in Rust and WebAssembly optimized to deliver sub-10ms semantic search queries for real-time voice and conversational AI.
What it would actually take: Building sub-10ms vector search requires a custom in-memory vector indexing engine (such as HNSW, IVF-PQ) written in Rust, compiled to WebAssembly for edge/client execution or distributed across edge nodes. It requires memory-efficient quantized embedding models, zero-copy deserialization, and custom hybrid search algorithms. This demands low-level systems engineering, vector index algorithmic research, and SIMD hardware optimization expertise.

Same idea, different domain
Nobody's really built a model & infra tool for Fintech yet.
