Why should you trust us?

Satisfied customers

Our first project was finished more than ten years ago, in 2008. We have helped a number of major European companies to transition their viewers from analogue to digital broadcasting. Since then, we have successfully created dozens of new devices and applications and become the leaders in STB development. So, the first reason to trust us is our experience and good references.

Robust development process in Video Delivery & DTV projects


The digital TV area is one of the most dynamic: competencies are getting outdated, technologies are developing quickly. That is why the industry seeks narrow expertise and  developers with versatile qualifications.


We form and dedicate our expert teams to targeted tasks as soon as the clients need that. That measure saves 30-50% of the costs. The average volume of these activities can result in 2000-3000 hours. Clients save around $20 000-30 000 on average.

Our solution


At least 15% of the working time all our developers spend on training and professional growth without exception


Due to our business model's specific nature, we continuously face tasks and challenges from different technological areas. That has allowed us to accumulate in-depth experience, which we are always ready to share with our clients and partners


Working with us, clients get access not only to the core team but also to the knowledge base accumulated by Promwad over the years

We build effective relations with technological vendors


Vendors seek support and engineers on the local market. Besides, they struggle while promoting their products and accepting adequate feedback; hence, it is challenging to eliminate bugs and deliver high-quality SDKs.


Through a comprehensive approach and a well-established development & management process, we can reduce time and labor costs on projects that require vendors' solutions integration by 7-12% of the market average. With an average volume of $500 000-700 000, this 7% can save customers $50 000 and more.

Our solution


We integrate various vendors' solutions into our customers' products, so we often see bottlenecks or undetected benefits that add value to our interaction with vendors


Not being a manufacturer, but rather a user or even a consumer, we can form real and honest feedback on performance, usability, and quality of this or that solution
