Rossum vs Double

Rossum reads invoices, purchase orders, bills of lading, and other transactional documents, then extracts, validates, and posts the data to your ERP. AI agents ingest files from email, scanners, PEPPOL, or shared drives, run them through the Aurora Document AI engine, and route exceptions to a human validation screen when needed. The platform supports 276 languages plus handwriting and learns from user corrections over time.

OCR tools that only pull text leave your team to fix errors in spreadsheets. Rossum cross-checks extracted fields against master data, ERP records, and business rules, infers GL codes and tax codes, and triggers approval workflows or vendor emails automatically. Business and Enterprise tiers add duplicate detection, intelligent mailboxes, custom webhooks, and certified connectors for SAP, Coupa, Workday, and Oracle.

Rossum targets finance and operations teams drowning in AP paperwork, logistics companies processing shipping documents, and enterprises facing e-invoicing mandates. More than 450 brands use it, Everest Group named Rossum a Leader in its 2026 IDP PEAK Matrix, and Coupa acquired Rossum to extend its spend management stack.

Double is a lead research and enrichment platform for sales and marketing teams. You upload a prospect list, and Double uses GPT to search the web and answer custom questions about each company or contact. Instead of manually Googling accounts, you define the criteria that matter to your outbound motion and get answers back at scale.

The product focuses on qualifying and enriching leads in bulk. You can ask whether a company is remote-first, SOC II compliant, B2B, building an API product, running a marketplace with payments, or shipping a mobile app as its core offer. Double returns sourced answers you can review alongside LinkedIn and email data in a table view.

Double also finds verified work emails by aggregating more than ten private data sources. The site positions this coverage as broader than tools like Apollo and RocketReach. Teams at Amazon, Indeed, and Gartner are shown on the homepage, and the company is backed by Y Combinator.
