As an independent innovation partner, we work on a ‘fee for service’ basis, providing engineering support as an extension of our clients’ team.

We focus on supporting original equipment manufacturers (OEMs) that aim to scale to volume production, paralleled with our effort to evolve the company from a product engineering firm to a fully integrated manufacturing company. Our ideal customer provides the potential for Gray Optics’ integration into the project at the concept phase, then onto manufacturing scale-up for regulated and non-regulated devices. 



We believe that for our company to be successful, our customers must be successful – therefore, our customers are at the center of everything we do. In support of our mission, we are committed to building a collaborative culture and promoting the strength of our team.

Our core values are:
