why we exist

1 – Creating hardware today is time consuming and expensive.

2 – This friction constrains the development process, leading to suboptimal products and high barriers for anyone with a new idea.

3 – Smarter design tools and production processes enable more people to invent.

4 – We’re building a world where innovation is radically accelerated and everyone feels empowered to create and improve our lives.


Plethora streamlines product development.

We start with the design phase: our CAD Add-in & Web Platform provide instant information on manufacturability and price. This avoids the usual back-and-forth – letting you focus on making parts, not managing suppliers.

Next is purchasing: if your design is manufacturable, you’ll receive a quote with turnaround, quantity, and pricing flexibility. Once you optimize your quote, you can share it with your team or check out on the spot.

After placing your order: our automated software converts your design into the instructions our factory uses to produce and inspect your part. Since everything is done in-house, you know you’ll receive your part on time and to spec.

We believe our “full stack” approach is the only way to truly transform the production process into an on-demand system of creation.

The Plethora Guarantee

We will make your parts to spec and ship them on-time – or your money back. We will always be direct and honest in our communications and work hard get you the best outcome.

what’s next

We started with CNC milled parts in our San Francisco factory, but that’s just the first step.

We have a big vision for the future of manufacturing and engineering. A future where engineers are able to make better designs and produce them effortlessly – with the help of powerful interfaces and flexible production technologies.

We’re always learning what’s important from our customers and quickly developing new capabilities. In the near future, look for new production processes, materials, finishing options, and much more.

Plethora will not stop until everyone on Earth has easy access to every tool they need to turn their ideas into reality. It’s going to be an exciting ride.

Flexibility and speed mean I can have exactly what I want as soon as I need it, so I can iterate much faster than before.
