Company
Fourteen years, two names, one discipline.
B2B Solver Limited is a digital transformation company working across public health and humanitarian response, government digitisation and commercial platforms — from Dhaka and Cox's Bazar.
B2B Solver Limited is a digital transformation service provider, powered by a team of professionals with over twelve years of collective industry experience. The company addresses complex digital challenges for both profit and non-profit organisations, delivering solutions that optimise operations, enhance productivity and enable sustainable growth.
Our clearest expertise is in public health and nutrition within complex humanitarian contexts — including the Rohingya refugee response in Cox's Bazar, in partnership with UNICEF. We support data-driven programme implementation through digital solutions that strengthen monitoring, reporting and coordination.
From requirement analysis and business architecture design through to full-cycle software development, we deliver end-to-end. Where advanced technologies — machine learning, computer vision, generative AI — solve a real operational problem, we apply them. Where they do not, we say so.
Background
In 2012, a group of graduates from the University of Dhaka and the Bangladesh University of Engineering and Technology came together to build a technology-driven startup. From its early days, Binary Blue Soft earned the trust of international outsourcing clients, particularly in Australia and the United Kingdom.
In the wake of the COVID-19 pandemic, the stakeholders rebranded the organisation in 2022 as B2B Solver Limited. Backed by a renewed sense of purpose and a fresh team, B2B Solver Limited continues the legacy established by Binary Blue while charting a new course in digital transformation.
Mission
To empower organisations through practical software and digital transformation — delivering customised technology that improves operational efficiency, drives growth, and creates durable advantage.
Vision
To be the partner organisations turn to when the system has to work — setting the standard for engineering discipline in the environments where getting it wrong has consequences.
