I am specifically interested in knowing which bodies regulate processes for financial technology companies.
I will go from general to specific.
Generally, the CAC regulates all companies, tech companies inclusive.
The NOTAP (National Office of Technology Acquisition and PROMOTION) regulates issues around technology transfer. Say for example , there is a software licensing agreement between a foreign entity who is the licensor and a Nigerian company who is a licensee.
The National Information Technology Development Agency (NITDA) was formed for the SPECIFIC purpose of implementing the Nigerian IT Policy and coordinating IT development within the country. NITDA is responsible for the development of IT in Nigeria through regulatory policies AND STANDARDS.
In terms of specifics, the nature of your solution will determine what body will regulate you. Finance; CBN. Securities: SEC. Beverages: NAFDAC.
Of course you need to speak with a lawyer and provide details to get a comprehensive overview.
