We Raised $50M to Build Composable Vector Search as Core Infrastructure

Today we’re announcing $50 million in Series B funding, led by AVP, with participation from Bosch Ventures, Unusual Ventures, Spark Capital, and 42CAP. Retrieval Is on the Critical Path of Every AI System Every serious AI workload — RAG, agents, multimodal search — depends on retrieving the right information, at the right time, under real constraints. Teams prototype with whatever is convenient, then hit walls in production: indexes that stall under writes, filtering applied after search instead of during it, tail latencies that spike under load.
