How to Get Started
Discovery Call
Help us understand your engineering needs
and learn if we're a good fit for the project.
Proposal
We'll estimate the scope of work and timeline,
then send you a contract to start.
Project Kickoff
We begin. We work with you to design, test
and build your product, device or machine.
A straightforward process to design and engineer your product at a competitive price.

We design your product with 3D CAD modeling, validate and test with advanced engineering analysis, fabricate a successful, working prototype, and introduce you to manufacturers capable of high-volume production to bring your product to market.
We start with a Discovery Call to learn what your product, device or machine does, why it’s needed, and how it works.
Project Estimation
We quote the scope of the project and the timeline to complete work based off:
1.) Engineering Time Needed
2.) Material Costs
3.) Tooling Costs
Design & Analysis
We create a
(CAD) model
of your product and use the best design and analysis software to
simulate how the product will function in the real world.
We determine the best materials and manufacturing processes to ensure performance requirements are met and
products are designed for manufacturing.
Prototype Fabrication
Prototypes allow you to
see, hold and feel your product
before committing to high-volume manufacturing. We order and assemble the parts needed to
fabricate and deliver your prototype in a timely manner and at a competitive price.
Production
We work with a
network of skilled manufacturers able to handle high-volume production, packaging, and shipping of your product.
This is where we hand the reigns back to you to enjoy the profits of your investment.
