Overview

Base64.ai is a document-processing AI company founded in January 2020 by Ozan Bilgen, a former software engineer and manager at Microsoft, Netflix, PayPal, Uber, and Palantir. The Delaware-incorporated company is backed by Sequoia Capital, Long Journey Ventures, and Prime Zero Ventures.

The platform reads documents such as invoices, IDs, tax forms, and contracts through an API or no-code connector, matching fields against more than 2,800 prebuilt models rather than requiring a customer to train a model from scratch for each document type. Add-on modules cover signature verification, PII redaction, and fraud detection for regulated industries.

Base64.ai is built for enterprises processing high document volumes, from insurers to logistics firms. A free tier is available to get started, and per-page OCR extraction begins at roughly one cent per page; exact tiered plan pricing beyond that is not published and requires a sales conversation for volume commitments.
