About Us

Investment One Global Advisors Limited (IOGA) is a 100% owned subsidiary of Investment One Financial Services Limited in Nigeria. We were set up as a subsidiary in the UK to develop products for the African diaspora internationally and Pan-African investors and to support the Investment One Group’s growth of its financial services across the value chain. Investment One Global Advisors Limited was incorporated in 2021 as the international subsidiary of the Investment One Group as part of a strategic shift to provide global financial services to our clients.

Once authorised to provide financial services in the UK, we aim to provide sources of growth capital for small to medium-sized entrepreneurial businesses in the impact and development space alongside a wider service offering that supports the investment advisory sector by providing access to attractive, alternative, asset classes.

We have a team of experienced professionals who have charted the path of Investment Banking in the UK for over 30 years and have provided premium quality service in providing portfolio services, private equity and private debt services and other investment management services.

Our mission is to assist Africans in the Diaspora, business owners and the investment community to optimize investment opportunities in the global market, reduce loss-related risks, make informed financial decisions and enhance wealth creation across board. These we intend to achieve by building strategic and sustainable partnerships with our clients in areas of financial services, asset management, transaction advisory and Anglo-Nigerian trade expansion.


Following authorisation, our initial product offering will span:
