About BLACK iz Limited

BLACK iz Limited, which also goes by BLACK iz IT, is a technology company headquartered in Dhanmondi, Dhaka, Bangladesh. The name covers a group of related businesses presented together on one website: web and software services, online marketing, IT training, camera and networking systems, and an interior design arm. The company says it has served more than a thousand clients over the past seven years, and that it works for organisations of all sizes as well as individuals.

Web design, e-commerce and online radio or TV sites

The web team designs and builds websites, e-commerce stores and WordPress sites, and it customises content management setups to suit each client. It also builds online radio and television sites. Overseas customers are among its web clients, alongside those in Bangladesh, according to the company, and its web work is aimed at customers worldwide.

Bespoke programmes and the IT service arm

The software arm builds bespoke programmes and mobile applications, and it runs an IT service management line as well. The IT service arm is presented as ongoing support for organisations that want their systems run reliably, and the company describes its broader IT offer as a service for businesses of all sizes.

Digital marketing and bulk messaging

The marketing arm covers search engine optimisation, social media marketing and total online marketing. It provides bulk SMS through masked sender identities, and it offers short-code numbers and gateways for businesses that message customers at scale. Press release distribution and an e-marketing analyser complete the marketing set.

Interior and exterior design through iNEXTerior

The design company iNEXTerior, which sits within the group, handles interior design and fit-outs for offices, apartments, restaurants and cafes. It also produces exterior design and two-dimensional and three-dimensional building plans. The site describes the company as specialising in modern interior and exterior design, including the construction of offices, apartments, restaurant interiors and cafe interiors.

Security, networking and camera systems

For buildings and sites that need monitoring, the company supplies IP and CCTV camera systems and networking. This work sits alongside its IT service management and software offer, so one provider can cover the systems and the surveillance around them.

Training through the BLACK iz IT Institute

The BLACK iz IT Institute runs courses in search engine optimisation, creative web design, professional graphics design, freelancing and outsourcing, Python, dynamic web development and software development. The company describes the courses as practical training for people who want to earn from online work, and advanced SEO and web design courses are among the listed offers.

One group, several brands

The group presents several brands under one roof, among them the IT arm, the design company, the training institute and a hosting brand, along with an SMS marketing solution, an e-marketing analyser and a security store. Each brand covers a particular part of the group's work, and the company's own website links them together.
