We can be an extension of your team supporting specific development activities, or manage the entire tech transfer process from cradle to grave.
Business Meeting at Small Table


Our team was trained by the National Science Foundation to develop business models based on evidence, not intuition. We conduct interviews and surveys with key stakeholders, then use our proprietary framework to make go-to-market decisions based on data.

Printing Plastic Skull

Human Centered Design and Engineering

Our team is comprised of experienced engineers who employ Design Thinking principles to empathize with end-users, innovate the most elegant solutions, then translate concepts into specifications. The latest CAD and 3D printing tools help accelerate iterations.

Metal Drills

Prototyping and Scale-up

With a wide range of 3D printing, metalworking, and polymer forming equipment, AMI Brilliant has the facilities to create prototypes from low-volume representations to pilot scale production-intent products. We can even accommodate your needs for clean-room production.
