Estimating, bidding, project controls, and cash flow — built by a fabricator, for fabricators.
Most construction software is built by people who have never priced a job, never chased a mill order, and never had to make payroll on a Friday.
We build from the other side. StructuPath is run out of an AISC-certified fabrication and erection shop in Denver — robotic welder, real tonnage out the door every week. Every tool in this org was built to solve a problem that was costing us money that week, then hardened until it was good enough to hand to someone else.
If it's public here, it runs in production somewhere.
| Product | What it does |
|---|---|
| SteelCFO | Financial command center for steel contractors — job costing, 13-week cash forecasting, AR/AP, risk scoring, AI analysis |
| IronForge | 50-state wizard for ironworkers going independent — LLC formation, licensing, bonding, insurance, union signatory |
| pi-steel | Structural steel estimating as agent skills — AISC takeoffs, BOMs, tonnage roll-ups, vendor RFQs |
| Bid Extractor | Pulls RFQ data out of Gmail, Outlook, BuildingConnected, PlanHub, and Procore, scores it by priority, processes locally |
Our largest build is an operating system a structural steel contractor runs daily work on — model coordination, shop production, quality evidence, field execution, procurement, and project controls. It isn't public, but it's the reason the public repos work the way they do.
Shipping this much software with a small team meant building our own tooling for running coding agents. We open-sourced it.
| Tool | What it does |
|---|---|
| herdr-swarm | Parallel coding agents on one repo, safely — worktree-per-agent fan-out, live change visibility, review-first harvest |
| herdr-browser | Drivable agent-browser pane with live streaming, real interaction, console capture, and recording |
| herdr-guard | Cross-agent command policy — audit, alert, and interrupt dangerous shell commands |
| herdr-conductor | Orchestrate a feature-delivery team as visible agent panes |
| bullpen | Durable agent harness in Rust — resumable sessions, crash recovery, sandboxed execution, hierarchical delegation |
| jig | Local-first software factory — repeatable phased agent workflows across Git repos |
