Design Research

We begin with targeted market research as well as a broad spectrum of aesthetic, conceptual, and functional explorations.

Concept Development

Concept is paramount to Castor. Driven by inventive storytelling, we ideate through hand-drawn and digital processes, refining direction in partnership with our clients along the way.


Castor has a breadth of experience across a wide range of prototyping processes, including 3d printing, CNC, and machining, in addition to unique hand-made techniques and fabrication. This allows us to offer prototypes that best communicate the look, feel, and functionality that will inspire the final product.

Market Preparation

Once the design is finalized we follow through to production, including technical drawing packages for manufacturing. Castor has amassed a large vendor base, offering options for a wide variety of material and production processes with partners in North America, China, India, and East Asia.

Branding and Packaging

We offer logo design, branding decks, and graphic assets as well as packaging design services in order to align seamlessly with the finished product. We believe in a unified product and packaging experience for buyers, and put as much thought and innovation into the unboxing as we do the product itself.
