Robust Development Process in Video Delivery & DTV Projects


The DTV industry's rapid evolution demands developers with narrow expertise and diverse qualifications to remain competitive.


We swiftly assemble dedicated engineering teams, saving clients 30-50% in costs. The average workload ranges from 2000 to 3000 hours, with potential savings averaging $20,000 to $30,000.

Our solution


Promwad's developers dedicate at least 15% of their time to training and professional growth.


Working with companies from various industries, we solve diverse technological challenges, which enables us to gain versatile experience that benefits our clients.


Our clients can access our core team and tap into the vast knowledge base we've accumulated over the years.

Collaborations with vendors

Our partnerships are another testament to our excellence. By working with top chip vendors, we can employ the best electronic components for your set-top boxes and receive priority technical support to keep your systems up-to-date.

We Build Effective Partnerships with Technological Vendors


Vendors require engineering assistance in the local market, seeking aid in promoting their products and gathering valuable feedback. Consequently, eliminating bugs and delivering high-quality SDKs pose a significant challenge.


Our tailored engineering and management processes allow us to reduce time and labour expenses for projects involving vendor solutions integration by 7-12% compared to the market average. Given an average project volume of $500,000-700,000, the 7% reduction can save our customers $50,000 or more.

Our solution


We integrate various vendor solutions into our customers' products, which enables us to identify bottlenecks and undetected benefits. This firsthand experience enriches our interactions with vendors.


As the users and consumers, we offer transparent and thorough feedback on the vendor products' performance, usability, and quality.
