Independent toy invention studio · Portland, Oregon

Keep building. Keep playing. That's the point.

Toy concepts invented, prototyped, and safety-engineered in our own shop, then handed to your team certified, costed, and ready to tool.

01 · What we do

From the first sketch to a concept your factory can tool.

A

Invent

Original play patterns, developed with the retail shelf and the production line in mind from day one.

B

Prototype

Built and rebuilt in our own shop. Working samples, not renderings of a good idea.

C

Safety-engineer

Compliance is designed in house before you see it, so your lab confirms it instead of discovering it.

ASTM F963EN71CPSCISO 8124
D

License

You get the concept, the tech pack, and the person who built it on the phone when your team has questions.

Durable goods built to be played with outside. Not future trash.

02 · The inventor

Jeff Mumford. Inventor, with receipts.

We dream it. We build it. We break it. We fix it. We play outside.

04 · Working with partners

Four steps. No surprises.

01

Intro + NDA

A conversation first. Then a mutual NDA before anything unpublished changes hands.

02

Portal access

You get a login and see only the concepts shared with your company.

03

Prototype + tech pack review

Samples in hand, tech pack and compliance on the table, your questions answered by the builder.

04

License deal

Terms, royalty, and handoff to your factory. We stay on call through tooling.

05 · Request access

The concepts live behind the login.

Everything we've invented is unpublished and IP-pending, so it's shared with partners one concept at a time, under NDA. Tell us who you are and Jeff will review the request personally.

Requests go to a pending list. Nothing is shared until approved.
