GIZA Steel

What GIZA Steel does

GIZA Steel is a privately held, St. Louis-based software company that sells automated structural steel connection design software to structural engineers, steel detailers, and structural steel fabricators. Its core product, GIZA, performs connection calculations automatically using ASD or LRFD methods to AISC 14th and 15th editions (including NYC building code) and is differentiated by a native bidirectional integration with Trimble's Tekla Structures (versions 18–2024) and Tekla Structural Designer, allowing users to pull connection data from a Tekla model, run designs, and push results back so the joint is remodeled in real time. The company also offers GIZA Miscellaneous for secondary structural elements such as wall rails, railings, and stairs, and free GIZA Plugins that extend Tekla's own component library.

The business model is a pure software subscription with two published tiers — GIZA Lite at $75/month (standalone, no Tekla required) and GIZA Full at $195/month (bundled with the Tekla interface and plugins) — distributed via a self-serve, product-led growth motion with a 15-day full-feature free trial, direct website download, and lead generation through LinkedIn, YouTube training videos, webinars, and an annual booth at NASCC. Go-to-market is reinforced by an ongoing marketing partnership with Trimble/Tekla, including the Tekla Partner Spotlight webinar series. The company employs 11–50 people, discloses no external funding, and has not publicly reported revenue, suggesting a bootstrapped, founder-led operating profile built around niche domain expertise rather than venture-scale growth.
