The Problem

No one can build the LEGO they actually want.

Custom LEGO has always been a niche hobby for obsessives with spreadsheets and a BrickLink account. Most people who'd love a LEGO version of their dog, their wedding venue, or their startup's office have no way to make one. The few existing services rely on manual designers, take weeks, and cost a fortune.

GET A KIT IN 7 DAYS.

An AI app that turns any photo or prompt into a buildable brick model.
Edit the preview in-app, hit order, kit ships in a week with bricks and printed instructions.

Go-To-Market

Your first 100 customers.

Four channels, in order. None of them cost more than your time.

01
DM 50 LEGO creators on Instagram
Free kit in exchange for a build video. The first 5 yes-es become your first 5 viral posts. Look for AFOL accounts with 10K–100K followers.
02
Drop the demo in r/lego and r/AFOL
Post the magic moment, not the product. "Generated this LEGO version of my dog with AI" beats "Check out my new startup."
03
Soft-launch in Half Baked
125,000 founders in one send. Offer the first 100 readers a free entry-tier kit.
04
ProductHunt with a hook
Don't launch the product. Launch a free tool: "Generate your founder portrait in LEGO."

After 100, the remix marketplace flywheel takes over.
Top creators bring their own audiences and you stop paying for acquisition.
