About Alkali

GPAgent's own fund-neutral profile, written from public information. Updated Oct 5, 2026.

Summary

Alkali builds AI takeoff software for structural steel fabricators. It reads construction bid sets, automatically detects and counts beams, columns, joists, braces, and connections, and outputs a bill of materials with tonnage calculations, 3D model, and nesting plans. It replaces manual quantity takeoff and scope review that estimators previously did by hand across large drawing packages.

Go-to-market

Steel fabricators and estimators are the buyers, and they can start immediately without signing up through a browser-based tool that requires no onboarding.
