Your idea.
A real prototype.
In one session.
Hop on Zoom with Brandon. He builds your invention in CAD while you watch — then prints it. Pay only after you approve the design.
- Live — watch the CAD build itself.
- One sitting — no months of email loops.
- Don't like it? Don't pay.
What others take three months to design,
Brandon does in 2.5 hours.
Three things no firm will offer you.
You're in the room.
It's a Zoom. You watch the model build itself. See something off? He fixes it before the model rotates.
One sitting. Done.
What other firms take three months to design, Brandon does in 2.5 hours. Same Zoom call. Same day. No "FINAL_v47.step."
Pay after you approve.
You only pay after you're happy with the design. Don't love what we built? You don't pay a cent.
From napkin sketch to your invention in hand.
Real client. Real session. Real prototype. This is the format — Zoom, screen-shared CAD, parametric model coming together as the call goes on. Days later, your invention shows up at the door.
Watch it come alive.
Sketch becomes geometry. Geometry becomes an invention. Your invention lands on your desk. Three states. One session.
The napkin sketch
Bring whatever you have. A drawing, a photo, a broken part, a verbal description.
Live CAD model
Brandon builds it on Zoom. Parametric, manufacturable, edited in real time.
Your invention on your desk
The CAD is ready for any 3D printer. Days later, the prototype arrives in the mail.
90+ inventions already shipped.
We can launch the whole product.
After the design, Brandon's network handles everything that comes next — so you're not stitching it together yourself.
Everything you need to take a product from sketch to shelves — from one team that already knows your design inside and out.
If you don't approve it,
you don't pay.
Walk out of the session unhappy with the design — you don't pay a cent. The risk is on us.
Three moves. One session.
Hop on Zoom.
Bring your sketch, your broken prototype, the part it has to fit into. Brandon checks the idea against engineering and manufacturing reality.
He builds. You direct.
Screen-shared CAD. Sketches snap to the grid. Cuts, fillets, bores — happening in front of you. Speak up the moment something looks off.
You hold the invention.
The CAD is ready for any 3D printer. Days later, the prototype is on your desk. You also get a sharable 3D-viewer link.
Engineers, founders, tradesmen.
"I'd been quoted months of work. We had a working CAD file before lunch."
"Complex mechanical features and insufficient documentation. Brandon adapted and designed a workable, clever solution."
"12 years as a federal engineering customer, 13 as Chief Engineer at Lockheed Martin, 7 as a consultant. I wholeheartedly recommend The CAD Guy as a designer, contractor, and partner."
"The 90 minutes with the CAD guy were just what I needed. He led the conversation, answered every question, and built my first part. I was completely satisfied."
"I was clueless. Brandon walked me through every step with professionalism. His skills and creativity helped me put my invention to life. I recommend him to everyone."
"Turned a rough sketch into a working CAD file in one session. Sent it to my manufacturer that same week."
"Sat on this idea for three years. One day and a 3D-printed part later, I'm finally moving."
One session. No SOWs.

Describe your idea. Brandon tells you if it's a fit. You only pay after you're happy with the design.
Questions before you book.
"Pay only when I approve" — really?+
Yes. You only pay after you're happy with the design. End of the session, if you don't have a CAD file you'd send to a manufacturer, you owe nothing.
How long is the session?+
2.5 hours, live on Zoom. That's it. The reason we can compress what other firms drag out for three months is because Brandon builds the CAD parametrically in front of you — every change happens in seconds, not weeks of email.
Can you also handle manufacturing and shipping?+
Yes. After the design is yours, our network covers manufacturing, logistics, packaging, warehousing, shipping, branding, and online services — so you don't have to stitch a launch together yourself.
Is this for software or apps?+
No. This is for physical products — parts that get made by 3D print, CNC, sheet metal, or injection mold. Mechanical, consumer, medical, industrial. Not for UI design or PCB layout.
What if my idea is just a sketch?+
That's the most common starting point. About 70% of clients walk in with a hand-drawn sketch or a verbal description. Brandon's job is translating it into engineering geometry.
Do I need to know CAD?+
No. You bring the idea. He brings the CAD, manufacturing knowledge, and DFM instincts.
Who owns the file?+
You do. Full transfer on delivery. NDA available. Take it to any manufacturer, anywhere.
Bring the napkin.
Leave with the invention.
One Zoom. One session. You only pay after you're happy with the design.
