What our customers are saying
One particular capability where they really stand above competitors is project management. This is done in a professional way, and we have quite high complexity involved. They are doing an outstanding job.
Global Commodity Manager / Multi-national Medical Device Company
They’ve been a good partner – good communication and meeting our needs…Open and honest. Good partnership.
Business Unit General Manager / Global Medical Device Company
The Aptyx team did an excellent job converting brass gears to plastic. Because of the design challenges, deep expertise in gears and over-molding was crucial. They also converted an expensive, labor-intensive part with quality issues to two-shot molding, which dramatically reduced cost, improved quality, and easily met the production needs. Apytx came through for us because of very good program management and good technical expertise.
Lead Principal Engineer / Global Medical Device Company
Working with your team has been one of the best contract manufacturing interactions ever. They made the whole thing happen even when it was chaos on our end.
Director of Regulatory Affairs/Product Development Manager / Medical Device Startup
The team at Aptyx is a pleasure to work with. They understand & act like true partners. I routinely hold them up as the model of the type of supplier that we need.
