What Our Clients Are Saying

Aliya Leekong
Creator of Issa’s Edible Adventures
Zco’s creative team helped me bring to life this child and her fantastical and educational adventures. Their technical team made sure the game played well and had a smooth launch.

Rajia Abdelaziz
CEO of invisawear
Zco helped us create an app that integrates directly with our proprietary hardware. Through every phase of the project, their team worked with us to create a product that will help protect people.

Kendrick Delaney
Senior Business Development Manager at Aliv
One thing that Zco did very well was management. They had a meeting at the beginning of the week to review functional requirements with the client. They made sure that we all agreed upon what they would be working on. Then, later that week, they had another meeting to articulate what they’d built, and they walked us through that bit-by-bit.

Charlie Hoertz
Global Project Manager at ASK Chemicals L.P.
We’ve worked with multiple software engineering firms on many internal enterprise applications throughout the years. There is a major difference with Zco Corporation, though. Their production quality is first rate, and their pricing is transparent. With other companies we’ve experienced poorly estimated work that ultimately results in additional costs. Zco, on-the-other-hand, gives thorough estimates that reflect true final costs.

Rick and Maria
Creators of Zentangle
Zco provided what we asked them for, and that grew out of lengthy meetings with them. Our team would go up oftentimes, four or five of us, and we’d sit in the conference room for hours, or they would come down and see us. Many whiteboards and many user interface documents later, we hit upon the basic format. The user interface was over 100 pages. It’s a fairly sophisticated app right out of the gate.

Areej El-Jawahri
Areej El-Jawahri, Associate Director of the Massachusetts General Hospital Cancer Outcomes Research and Education Program (CORE)
Our research team has successfully worked with Zco Corporation over the past several years to develop cutting-edge supportive care interventions mobile application to address the needs of patients with Cancer. We are grateful for our collaboration with Zco and are looking forward to continue to work with them to improve the lives of our patients and their families.

- As a first step a NDA is signed, guaranteeing that you and you alone own the project’s intellectual property.
- Through building our relationship we provide you our perspective on the user experience, design, what functionalities can be moved to a phase two or even how you can transition your product into a more business-oriented structure.
- We take your comments into consideration throughout the development process to ensure we are working towards your desired result. At the projects conclusion, all assets including the source code are signed over to you.

Zco’s app development hourly rate is less than $60 per hour. An average app project might cost about $30,000, with features and complexity raising or lowering the price accordingly.
