Company profile
researched Aug 2026Extend provides document processing infrastructure for AI agents and data pipelines. Its APIs parse, extract, and split documents, converting PDFs and other unstructured files into structured, high-quality data that downstream applications and agents can consume. The company states its systems process millions of pages every day.
Beyond core models, Extend ships a toolkit intended to make document pipelines production-ready: confidence scoring backed by a multi-pass review agent that flags uncertain outputs, selectable processing modes trading off latency, cost, and maximum accuracy, a Composer optimization agent that refines extraction schemas from uploaded examples, multi-step document workflows with parsing, splitting, extraction, validation, and routing plus versioning and durability, and a Studio interface for schema iteration, evaluations, and regression testing by domain experts. Developer access is available via Python and TypeScript SDKs and a CLI, distributed through the extend-ai package.
The company publishes benchmark results comparing its parsing against alternatives. On RealDoc-Bench, which it describes as testing production documents where layout, reading order, and field relationships affect answer quality, Extend Parse 2.0 reports 95.7% field-level answer accuracy across 1,359 prompts and 581 documents, ahead of Extend Parse 1.0 (90.4%), Gemini 3.5 Flash (89.04%), Azure DI (88.8%), and AWS Textract (70.5%).
Business model
Extend sells document processing APIs and tooling to engineering and AI teams, offering a free trial entry point alongside demo-led enterprise sales. The product can be consumed as a hosted cloud service or deployed self-hosted on a customer's own infrastructure, which supports customers in regulated industries that must keep sensitive documents in-house.
Traction
Extend states that it processes millions of pages daily. Brex reports Extend powers key document workflows across 30,000 customers; Flatiron Health reports replicating six months of work in two weeks and scaling across a network covering 5 million people with cancer; Vendr reports Extend produced the best results in a competitive evaluation.
Latest developments
Extend announced Parse 2.0, described as a layout-first parsing API, and published accompanying benchmark results on document Q&A, layout, cost, latency, and vertical-specific performance.

Market position
Extend competes in document parsing and extraction against cloud services such as Azure Document Intelligence and AWS Textract, open-source tooling, and general-purpose foundation models. Customer testimonials from Brex, Vendr, and Flatiron Health describe Extend outperforming alternatives in evaluations, and Extend's own benchmark places Parse 2.0 first on its RealDoc-Bench document Q&A test.
Extend positions its accuracy on difficult production documents as its primary differentiator, publishing head-to-head benchmark comparisons against its prior version, foundation models, and cloud document AI services. It also emphasizes surrounding production tooling — confidence scoring, evaluation and schema-iteration interfaces, workflow orchestration, and an optimization agent — rather than models alone, plus self-hosted deployment and compliance certifications for regulated buyers.
Technology
The platform combines parsing, extraction, splitting, and classification APIs with orchestration and evaluation tooling. Features include a layout-first parsing engine (Parse 2.0), a multi-pass review agent for confidence scoring, multiple processing modes for latency-, cost-, or accuracy-optimized runs, the Composer agent for automated schema refinement, durable versioned multi-step workflows, and a Studio environment for evals and regression detection. Security and compliance include SOC 2, HIPAA, and GDPR, regular third-party penetration testing, and self-hosted deployment.
Go-to-market
The company markets through a self-serve free trial and developer documentation with Python, TypeScript, and CLI clients, combined with a book-a-demo motion for enterprise buyers. Customer stories from Brex, Vendr, and Flatiron Health and published benchmark results serve as primary proof points, and prospects are described as running competitive bake-offs against other vendors, open-source tools, and foundation models.
AI and engineering teams building document-driven applications, including companies in finance, real estate, logistics, and healthcare. Named users include Brex, Vendr, and Flatiron Health, and the company says it is trusted by Fortune 500 organizations in regulated industries.
