What We Built

Kavanagh Industries designed two custom PCBs simultaneously from scratch — a Micro-ATX Jetson AI carrier board and an extended PCIe AM5 companion card — that together form the RigidStation dual-brain AI workstation. Both boards required original architecture, custom I/O, and bespoke mechanical design.

Side by Side

Every bar represents the same work. The difference is parallelism, AI tooling, and an engineer who knows what matters. Each row is scaled to a 60-month maximum.

The Force Multiplier Effect

AI does not replace the engineer. It amplifies the engineer. Every hour of expert human judgment is multiplied by AI's ability to research, document, generate, and verify — turning one person's focus into a team's output.

"The question is not whether AI replaces engineers. The question is whether the engineers using AI will outcompete the engineers who aren't. One person with the right tools and thirty years of knowledge does not need a team. The team needs to keep up with them."
— Shaun Kavanagh, Founder & CEO, Kavanagh Industries LLC

What This Changes

01
Sovereign Development
Small teams can now develop hardware that previously required large organizations. The gap between a startup and a corporation is closing — fast. IP doesn't have to leave the building.
02
Speed as a Weapon
3–5 year hardware programs become 9-month programs. In defense, in industrial automation, in sovereign computing — the team that can iterate fastest wins. AI collapses the iteration cycle.
03
Expertise × AI
AI doesn't replace thirty years of engineering judgment. It amplifies it. The engineer who knows what to ask, what to verify, and what to build is now armed with an entire research team, a documentation team, and a code generation team — in one tool.

Your Project. Your IP.
Your Timeline.

KI brings this force-multiplier approach to every engagement. Hardware consulting, PCB design, AI integration, sovereign architecture — built by engineers, not committees.
