Extend
Document processing API from New York that parses, extracts, splits, and classifies hard documents for AI agents and data pipelines, with self-serve credit pricing.
Fintech, health, and real estate engineering teams that process loan files, medical records, or forms at volume and need high field-level accuracy.
Non-technical teams that want a finished vertical app, or buyers processing a handful of documents a month who do not need an API.
Verdict
Extend is a document processing company in New York, New York, founded in 2023 by Kushal Byatnal, an early engineer at Brex, and Eli Badgio. Its APIs parse, extract, split, classify, and fill documents across 35+ file types, with layout models for tables, handwriting, and signatures, a review agent that flags uncertain outputs, and cloud, BYOC, or hybrid hosting. It matters because document errors flow straight into lending, claims, and clinical decisions, and Extend gives engineering teams accuracy plus the evaluation tools to prove it.

Review Excerpts
Below are excerpts from public reviews. Our team scoured public reviews, forums, and chat rooms to get a balanced view of customers' experience with this company. Paid reviews and pay-for-play sites such as Clutch were excluded.
“We were able to replicate 6 months of work in 2 weeks (!) with Extend. We're now scaling this up across all 5 million people with cancer in our network, truly transforming our work against this disease.”
“We tested AWS, foundation models, and newer vendors, and evaluated options on latency, accuracy, and the developer experience. Extend was the only one that could hit our performance bar, with the tooling we needed to scale.”
“We did a bakeoff, and Extend had the best results of any solution on the market. It eliminates an entire class of engineering problems around accuracy that we don't want to worry about.”
Performance-mode extraction costs 5 credits a page including the automatic parse, about $0.63 for a 10-page document on Pay As You Go, roughly four times the Light mode rate, and BYOC hosting is limited to Enterprise.
