Vision & Mission
Our Story
The Connex Brothers Consulting Group is an Intelligence Organic Network that grows and evolves based on the experience of carrying out projects in partnership with experts who have success stories in various industries and business areas around the world.
We have developed an innovative business model and system that can grow together continuously by providing solutions that can overcome the limitations of human resources and information possessed by the client company, and solve problems, by discovering and selecting clients as partners who have growth potential and can create synergy.
Connex Brothers Consulting Group aims to provide differentiated and competitive consulting services that organically collaborate like the client’s internal organization based on professionalism and system-based communication and services for the client’s project, and derive responsible results.
For Korean Visitors
In reality, many companies still rely on the experience and intuition of decision-makers for important managerial decisions.
The lack of internal expert human resources, financial constraints, and the absence of accumulated and analyzed data are realities that many companies still fail in various projects because they cannot solve these problems. The development of IT, including AI, is providing a variety of foundations that can solve various issues and problems that companies actually have at a minimum cost today.
Connex Brothers Consulting Group believes that a network composed of partners who can provide more substantial and direct help based on their own success experience in actual excellent corporate sites, rather than human resources staying in consulting companies as consultants, can provide responsible support for solving client’s problems. We firmly believe that we can provide responsible and more competitive services that meet the needs of clients through this human resource network and the advanced technology-based systematic system of Connex Brothers Consulting Group.
We are a company that exists as a medium to systematically connect clients and Intelligent Network, and we are a company that was established to create value as a company that redefines the standard of corporate management consulting by helping this Network evolve and grow.
