Subgradient Labs builds AI products and services for ops teams, including Doc AI for intelligent document processing, PDF to JSON, and invoice OCR.
Our conviction
Subgradient Labs pairs research with delivery. We sit with leadership, pick use cases that move revenue or cost, then build and deploy the systems. Doc AI is one example: PDF fields out as CSV or JSON for finance and logistics teams.
Work spans strategy through production: AI operating models, document extraction, and automation with clear ownership. We design for audit trails, safety review, and scale you can measure.
Product
Intelligent document processing for invoice OCR and bill of lading extraction. Export structured data as JSON or CSV via workstation, REST API, or MCP.
Intelligent document processing (IDP) API for PDF to JSON, invoices, and shipping docs
Doc AI is a document processing and PDF data extraction API. Convert PDF to JSON or CSV for invoices (invoice OCR), bills of lading, resumes, bank statements, and contracts. Layout-aware OCR, confidence scores, REST API, and MCP tools for agentic document processing. Zero retention by default.
We invest in safety engineering, interpretability, and compliance because enterprise buyers need systems they can audit and defend.
Red-teaming, operational guardrails, and safety checks ship with every deployment.
Open research, clear architecture docs, and client visibility into how systems handle data.
Oversight, compliance review, and value checks stay in the loop as systems move to production.
Share the workflow or document problem. We bring research, engineering, and a clear plan.
