About Us

What do we do?

Being the link to Africa

The world today is evolving, and so are technologies and businesses that aim to make the world a better place. As those develop, the global village becomes smaller and smaller; however, an entry into the African market can be challenging. 

Nevertheless, where there’s a challenge, there is always a solution. We offer international companies the opportunity to use Sierra Leone as “a beta site” to expand in Africa.

Why Sierra Leone?

Sierra Leone is unique for testing innovations because of its three primary conditions:

  1. Small population 
  2. Teachable HR possibilities
  3. Affordable work power 

With our combined knowledge, we help you to springboard your business on a national level and overcome the challenges of setting up an operation in Africa.

How do we do that?

  • With our rich experience in operating businesses in Sierra Leone, we can create links with targeted audiences, the government, and other institutions to ensure smooth transactions and operations in the country.
  • We make necessary arrangements to ensure soft launching, operation, and achieving business goals.
  • We escort the business throughout the testing process and guide or collect feedback and measure the outcome of the testing. 
  • We locate potential businesses in the country to promote the client’s services or applications while developing a strategy for the client to reach new businesses.
  • We provide legal services for quality representation throughout the process.
