inventors & startups

HMD offers a comprehensive range of engineering and design services to assist our clients in any or all phases of their product design and manufacturing process.

Our flexible design team will work with you on a personalized approach for your product needs no matter what stage of development your invention is in.


Whether you have just an idea and sketch, or you already have a homemade prototype, HMD's team with a combined 20 years of design and engineering experience can help you develop your concept into a viable and manufacturable product. 


From marketing, finding investors, or crowd funding, a physical proof-of-concept prototype is vital to the success of a new product.  HMD can develop the necessary CAD models to have prototypes made yourself, or using our industry contacts in machining, casting, and 3D printing, HMD can provide you with a working prototype.

product Refinement

New products might require several iterations before they move to a production-ready stage.  HMD will work with you on optimizing your product or invention for the next step.


We have strong relationships with industry providers, from plastics specialists to custom machine shops and foundries, who we can coordinate with to get your new product manufactured and on the market. 

continued development

After your product is manufactured and marketed, you may want to make changes or improvements. HMD can help you implement these changes to your next-generation product.
