Extend-AI — AI Document Processing Platform

Extend AI company developing an AI-native document processing platform with specialized LLMs for complex document parsing, extraction, and workflow automation.

Overview

Founded in 2023 by Eli Badgio and Kushal Byatnal, Extend AI is a Y Combinator-backed document processing platform that raised $17 million across seed and Series A rounds led by Innovation Endeavors in June 2025. The Extend AI company differentiates through specialized large language models and vision models built specifically for complex document formats, claiming 95%+ accuracy on tables, handwriting, and checkboxes. Their API-first approach serves technical teams at Chime, Brex, Flatiron Health, Opendoor, and Checkr for production document workflows.

The platform's adaptive learning system creates memory from processed documents to improve accuracy on similar files over time, while autonomous AI agents run experiments to optimize extraction schemas without manual intervention.

How Extend AI processes documents

Extend AI's specialized vision models handle complex layouts including large tables, handwritten content, and form elements through its document API suite covering parsing, classification, data extraction, and document splitting. The adaptive learning system creates memory from processed documents to improve accuracy on similar files, while autonomous optimization agents automatically refine extraction schemas through experimentation. The platform transforms documents into high-quality markdown for LLM ingestion and includes a production validation layer ensuring extracted information meets quality thresholds.

Use Cases

Financial Document Processing

Fintech companies process loan applications, bank statements, and identity documents, extracting account numbers, transaction histories, and personal information from varied formats while handling poor-quality scans and handwritten annotations.

Healthcare Records Extraction

Healthcare organizations automate medical record processing by extracting patient demographics, diagnoses, prescriptions, and lab results from clinical documents with checkboxes, tables, and physician handwriting.

Real Estate Transaction Automation

Real estate platforms process property documents including contracts, disclosures, and inspection reports, with the learning system improving extraction accuracy on similar property types and jurisdictions.
