Nigeria is home to a growing number of technology companies and young business leaders. Some business leaders have been seeking government help for their startup companies. Recently, several young entrepreneurs competed for a chance to tell President Muhammadu Buhari about their companies. Nigeria’s technology sector is growing, in part, because of ambitious entrepreneurs like Angel Adelaja, a Nigerian American. She is chief executive officer of a company called Fresh Direct Nigeria. It seeks to reduce the country’s dependence on food imports by growing cabbage and other vegetables in containers.
   First Direct Nigeria is designed for the expanding class of health conscious people who live in the city. A business called Grit Systems Engineering manufactures a device for measuring energy use. The company is the idea of Ifedayo Oludapo. " I am the founder of Grit Systems and what we make is a web-enabled multisource energy monitoring device—kind of like a utility meter, but it measures power consumption from all the different power sources you have, which is a big deal in an under-electrified environment like Nigeria. " Emma Okene leads Tracology, another Nigerian company. He and his team created a bar code that is placed on the front gate of a person’s home. By using a device that reads bar code information, waste collection crews will be able to know if the home owner has paid for their services.
   A total of 30 tech entrepreneurs competed for the chance to meet with the Nigerian president and vice president. Three were chosen, including Emma Okene of Tracology. He won a prize of more than $ 8,000. Last week, the Nigerian economy entered into a recession for the first time in more than 20 years. Government revenue is sharply reduced because of the drop in oil prices worldwide. So the government is interested in supporting technology companies, hoping they may be able to fuel the economy. Facebook founder Mark Zuckerberg was at the competition last week. He spoke at the end of his first visit to Nigeria. "You know, this trip has really blown me away by the talent of the entrepreneurs and developers in this country and by the focus on building something that’s gonna make a difference and gonna make a change. I think that if you keep on doing this you’re not only gonna shape Nigeria and all of Africa, but the whole world. " Nigerian government officials hope one of the startup companies can be as successful as Facebook.
