RAG & Knowledge Bases in Chicago.
Ground models in your data. Shipped by senior engineers in Chicago, async-first, fixed-price.
IRPR.io builds retrieval-augmented generation systems for Chicago teams that need LLMs grounded in their own documents, contracts, and knowledge bases. We ship RAG pipelines that retrieve the right context, evaluate answers continuously, and stay within cost budgets.
Our RAG stack covers embedding choice, chunking strategy, hybrid search (BM25 + vector), reranking, and guardrail evals. We have shipped production RAG for legal, healthcare, fintech, and enterprise search — every build ships with an eval harness so regressions are caught before users see them.
Chicago sits at the intersection of finance, logistics, and enterprise software. Home to Morningstar, Groupon, and a dense trading/fintech cluster, it's one of the most pragmatic, revenue-focused tech ecosystems in the country.
