Plusman is an engineering company founded on fundamental principles. For us, the purpose of technology is to make dreams possible.

We leverage our organization to deliver and disseminate products that make dreams come true.


Our technology is supported by integrity that comes from the summation of small, steady steps (mathematical integral). Our highest value is integrity in every job we do.

Non-centralized Expertise

Concentrating on strengths is limiting. Plusman constantly strives to explore new frontiers and acquire new expertise.


Excellent products require strong leadership (authority and accountability), and an important contribution to products is necessary to become a leader
