A managed service that indexes unstructured data (documents, videos, audio) and connects it to large language models to generate traceable, source-cited answers.

Nuclia, founded in 2019 in Barcelona, Spain, originally built an AI-powered search and indexing platform for unstructured data. In 2025, the company was acquired by Progress Software and rebranded as Progress Agentic RAG, a SaaS product that automatically indexes files and documents to fuel LLM and AI agent use cases. The platform ingests over 60 data formats (PDF, video, audio, spreadsheets, etc.) and provides RAG quality metrics to ensure output traceability.

It supports any major LLM (OpenAI, Anthropic, Google, Mistral, etc.) and offers multilingual capabilities. The product is sold as a managed service with SOC 2 Type II and ISO 27001 certifications. Pricing is consumption-based via AWS Marketplace.

No standalone financials for Nuclia are public; it now operates as a product line within Progress Software, which reported $1.57 billion in revenue for its fiscal Q2 2026 (ending May 2, 2026), up 40% year-over-year. The company claims 80% cost savings versus building RAG in-house and a 95% acceleration in AI readiness. The platform targets enterprise customers in legal, financial services, and media sectors, with specific use cases for generative website search, legal document analysis, and video indexing. The acquisition erased the independent Nuclia brand; all go-to-market now runs through Progress's sales channels.

Who buys this

  • Legal departments processing contracts, case law, and discovery documents
  • Financial services firms needing AI search over regulatory filings and reports
  • Media and publishing companies indexing video and audio archives
  • Enterprise IT teams deploying generative search on public websites

Strengths and what to watch

Strengths

  • Supports ingestion of 60+ file formats including video and audio, which many RAG tools do not handle natively
  • Provides RAG quality metrics and source traceability, addressing the hallucination problem in LLM outputs
  • Certified SOC 2 Type II and ISO 27001, meeting enterprise compliance requirements out of the box

Watch for

  • Nuclia no longer exists as an independent company; it was acquired by Progress Software in 2025 and fully rebranded, meaning customers are now locked into Progress's pricing and roadmap
  • No publicly available revenue or customer count for the Nuclia product line; all financials are rolled into Progress's broader $1.57B quarterly revenue, making it impossible to assess standalone traction
  • The RAG-as-a-service market is crowded with competitors like Vectara, LlamaIndex, and Cohere, and Progress is not a native AI company, raising questions about long-term investment in the product
