Infino is an open-source retrieval engine built for AI agents. It embeds functions directly in SQL so an agent can express complex questions in a single query, combining full-text BM25, vector search, and full SQL over one copy of your data in Apache Parquet files on object storage. The company has raised $7.5M from Bessemer to build one retrieval layer for agents.
What it does
Instead of maintaining a separate search index, vector database, and analytics warehouse, Infino runs natively over Parquet in your own storage bucket. Agents query it with SQL table functions such as hybrid_search, which blends keyword and semantic search in one call, and graph functions for linked-record traversal. Under the hood it uses a Rust engine, Apache DataFusion for SQL execution, and small language models to keep costs down.
Key features
- Hybrid search in SQL: keyword + semantic search combined in a single query function.
- Graph search: graph_search and graph_walk for exploring linked records.
- Full SQL over Parquet: complete SQL via Apache DataFusion, no data movement required.
- Open core: Apache-2.0 licensed, installable with pip install infino; deploy on-prem, self-hosted, or on Infino Cloud.
- Security posture: SOC 2 Type II, TLS and AES-256 encryption; data stays in your own bucket.
Who it is for
Infino targets teams building RAG pipelines and agent applications over large structured or semi-structured datasets: logs, incident records, and documents sitting in object storage that agents need to search and analyze without an ETL pipeline into a separate search cluster.
