Helios Investment Partners has exceeded its $1 billion target for its third flagship fund, which ranks as the largest vehicle dedicated to private equity in sub-Saharan Africa.

The London-based firm, which was set up in 2004 by Tope Lawani and Babatunde Soyoye, two former dealmakers from global buyout giant TPG Capital, said in a statement on Monday that it will shortly be closing Helios Investors III at its $1.1 billion hard cap. The fund launched in January 2014 and reached a $355 million first closing in March, according to a spokeswoman for the firm.
