Zco Corporation was founded by John Olapurath in 1989. He had originally started a software corporation called AimTech, which was bought out by a company owned by Microsoft co-founder Paul Allen. Following the sale, Zco Corporation was created to build custom software solutions for other businesses. With our roots in desktop and backend software, we expanded into the mobile arena as new devices came onto the scene. Now, industry guides like Appindex and Clutch place Zco on their lists of top Boston-area app developers, with Ankit Thakor including Zco on his list of top mobile application development companies in the USA. We celebrated our 25th anniversary in 2014; visit our blog to read and see more.

We have a great open-concept space in the Millyard Technology Park. We’ve played host to numerous networking events as well as presidential candidates. It is not unusual to see Zco employees doing yoga or playing badminton in our downstairs gymnasium or walking by the riverside in the adjacent city park. You may even see us charging up one of our electric cars in our onsite charging station.

Our goal as a company is to always push the state of the art. Our vision is to adapt to changing technology. Our philosophy is that more technology will come and we’ll be there!

Our clients come to us with a project in mind, hire us to custom build that project for them – whether it be enterprise software, mobile app development, or 3D animation – and then they own it outright.

We have successfully completed more than 500 projects across all platforms.

When our clients are successful, they may come back to us for repeat business, or recommend us to a friend, so it is really in our best interest to help them succeed. We do that through strong project management and communication, dedicated teams of quality engineers, and frequent milestone delivery. For consumer-facing projects, our marketing team offers consultation services to help formulate a go-to-market strategy.



We are proud members of the Concord, Nashua and Manchester Chambers of Commerce, and a sponsor of the American Marketing Association Boston chapter. We've offered our services free of charge to the Rotary Nashua West Club, which supports local non-profit organizations.
