What LETTRIA does
LETTRIA is a French DeepTech company, legally registered as TURFU SAS, that builds document intelligence and natural language processing software for enterprise clients in regulated industries. The platform combines a no-code Knowledge Studio, an API-driven NLP Studio, and the Perseus native graph infrastructure to convert complex documents — including those containing tables, diagrams, and multi-column layouts across 20+ formats — into structured, auditable knowledge graphs. Its differentiated GraphRAG technology, which pairs vector-based retrieval with knowledge-graph reasoning, is positioned to deliver verified, traceable AI outputs with reduced hallucination risk.
The company sells through an expert-led, consultative go-to-market: enterprise prospects enter a structured 12-week Pilot Program during which Lettria's data scientists, linguists, and technical directors scope requirements, build ontologies, and deploy GraphRAG solutions. Pricing is bespoke and contract-based (multi-year), rather than turnkey SaaS, and is anchored on regulated-industry pain points such as auditability, compliance, and document-heavy workflows. Primary verticals include Healthcare (AP-HP, Théradial, Wisecube), Finance (a leading banking group), Legal, Engineering (Alfa Laval), and Retail/Logistics (Leroy Merlin, La Poste, SIA Partners).
LETTRIA is venture-backed, having raised approximately €5M in seed funding from Galion.exe and Jezby Ventures in October 2022 and €4M in R&D funding in January 2025, with an additional ~$1M from Amazon Web Services in 2025. Headcount is in the 11–50 range, and the company operates from Paris and Provins, France, with distribution framed as global though primary commercial activity is concentrated in Western Europe.

LETTRIA competitors and assessment
Company assessmentDirect peers
- Sinequa: Enterprise search and NLP platform that builds knowledge graphs and AI-powered information retrieval for regulated industries (life sciences, finance, manufacturing). Directly comparable to Lettria's GraphRAG-based document intelligence stack.
- PoolParty (Semantic Web Company): Knowledge graph and semantic AI platform providing ontology management, text mining, and graph-based content enrichment — closely overlapping with Lettria's Perseus ontology and text-to-graph pipeline.
- Stardog: Enterprise knowledge graph platform combining graph database, vector search, and LLM-backed reasoning for data fabric and RAG use cases. Competes head-on with Lettria in graph-native enterprise AI.
- LightOn: French enterprise AI/LLM platform offering secure, private GenAI deployments for regulated industries — a direct geographic and product peer to Lettria in the French/European NLP market.
- Rossum: AI document processing platform focused on structured and unstructured enterprise documents, with strong traction in finance and logistics. Comparable in use case (document intelligence for regulated ops) though heavier in OCR/data extraction than graph reasoning.
Broad incumbents
- Neo4j: Leading graph database provider that has built out vector search, GraphRAG, and GenAI tooling on top of its core graph engine. A broader incumbent enabling similar GraphRAG architectures Lettria deploys.
- Cohere: Enterprise-focused LLM and NLP platform with retrieval-augmented generation capabilities. Competes with Lettria for the same regulated enterprise NLP/RAG workloads, though at much broader scale.
- Mistral AI: French frontier AI model developer building enterprise-grade LLMs with EU data residency. A potential partner or competitor depending on whether Lettria is used as the application layer above Mistral models.
- Hugging Face: Open-source NLP/AI platform offering models, datasets, and enterprise inference — provides the underlying NLP ecosystem against which Lettria's proprietary GraphRAG competes and on which it could build.
Emerging players
- Doctrine.fr: French legal-tech platform using NLP to analyze case law and legal documents for legal professionals. A vertical-adjacent peer demonstrating how French NLP startups monetize in regulated verticals.
