A Mortgage PDF Sent Mang-Git Ng on an Eight-Year Detour

Anvil
Anvil is a San Francisco software company that turns paper-heavy back-office processes into programmable digital workflows. Its API-first platform bundles PDF generation and filling, no-code webforms, embedded e-signatures (Etch), and workflow automation so developers and product teams can collect data, generate compliant documents, and get them signed without stitching together multiple tools. Founded in 2018 by Mang-Git Ng and Ben Ogle, Anvil serves customers across insurance, financial services, HR, real estate, healthcare, and education, and has raised $10M in Series A funding.
Artifex Software
Artifex Software is a San Francisco-based developer of document processing and rendering technology best known for Ghostscript, the long-running PostScript and PDF interpreter, and the MuPDF and PyMuPDF families of PDF tools. Operating on a dual-license (open source plus commercial) model for more than three decades, Artifex supplies SDKs, APIs and SaaS that let developers render, convert, extract and manipulate PDF and PostScript documents. Its technology reaches an estimated one billion-plus deployments and is licensed by OEMs and technology companies worldwide; in recent years the company has extended its extraction tools toward AI and RAG/LLM pipelines with products like PyMuPDF4LLM.
