About
Unstructured is an AI data infrastructure company founded in 2022 that raised $65M in Series B funding to build ETL tooling for large language model applications. The company specializes in processing unstructured data including PDFs, Word documents, HTML pages, images, and presentations, transforming them into clean structured formats suitable for LLM pipelines and retrieval-augmented generation systems. As enterprises adopt RAG and other LLM architectures, the ability to ingest and normalize diverse document types has become critical infrastructure. Unstructured offers both an open-source library and an enterprise SaaS platform with managed connectors to popular data sources including SharePoint, Confluence, Salesforce, and cloud storage providers. The platform handles document parsing, intelligent chunking, metadata extraction, and embedding preparation, serving as the ETL layer for enterprise AI workflows. Unstructured is widely adopted across financial services, legal, healthcare, and technology companies building production RAG systems at scale.
Most cited AI agent framework in 2026; LangGraph has 8,200+ GitHub stars. $25M Series A at $200M valuation. LangSmith observability platform for production agents. Used in majority of enterprise multi-agent deployments; 80K+ GitHub stars total.
About
LangChain was founded in 2022 by Harrison Chase and emerged from the open-source community as the dominant framework for building applications powered by large language models. Originally a Python library, it provided developers with composable building blocks—chains, agents, memory modules, and tool integrations—to connect LLMs with external data sources and APIs. The framework addressed a critical gap: making it practical to build production-grade LLM applications beyond simple prompt-and-response patterns.\n\nLangChain's product portfolio has expanded significantly, with LangGraph serving as its graph-based orchestration layer for stateful, multi-actor AI agent workflows. LangSmith provides observability, debugging, and evaluation tooling for LLM pipelines in production. The commercial LangChain Platform offers hosted deployment and collaboration features for enterprise teams. These products target AI engineers, ML teams at enterprises, and the broader developer community building agent-based systems and RAG pipelines.\n\nWith over 100,000 active developers and LangGraph accumulating 8,200+ GitHub stars, LangChain remains the most cited AI agent framework heading into 2026. The company raised a $25M Series A at a $200M valuation and has become deeply embedded in how enterprises build and deploy AI agents. Its ecosystem of integrations—covering hundreds of LLM providers, vector databases, and tools—makes it a foundational layer of the modern AI application stack.
