Iron Software Tech Stack

C# libraries for PDF, OCR, Excel, and data extraction across .NET and Java

Software Development Chicago, IL 11–50 employees Founded 2016 Privately Held

Iron Software builds developer-focused libraries for document processing, OCR, barcode scanning, and web scraping—primarily for C# and .NET engineers. The stack reveals a deliberate split: core libraries in C# and C++ paired with infrastructure (Docker, Kubernetes, AWS), plus emerging investments in RAG and LoRA for an internal AI assistant prototype. Hiring is accelerating (4 roles posted in 30 days) with engineering leading, but pain-point data points to marketing execution bottlenecks and capacity constraints on high-impact initiatives—a common pattern in bootstrap-scale component vendors scaling beyond developer adoption.

About Iron Software

Iron Software ships a suite of reusable libraries for C#/.NET developers handling PDFs, OCR, Excel, QR codes, barcodes, and web scraping. The company was founded in 2016 and operates from Chicago with an engineering base in Chiang Mai, Thailand. Libraries have been downloaded over 20 million times on NuGet across 95+ countries and are used by organizations ranging from single developers to enterprises including NASA, Tesla, and the US State Department. The product strategy is component-focused: engineers integrate libraries into their own applications rather than adopting a platform. Current priorities span infrastructure modernization (air-gapped server deployments), marketing funnel efficiency, and exploration of AI-assisted document workflows.
