Warburg Pincus and Goodwater Capital led a $100m Series D round in MoMo, Vietnam’s top payment app, with participation from Kora Management, Macquarie, Affirma Capital and Tybourne Capital Management. According to MoMo, 25% of the new funding will be used to support tech startups in Vietnam through MoMo Innovation Ventures, the company’s new fund. The capital raise is also a much-needed boost for MoMo to continue its fight in a brutal fintech war in the country, where 39 e-wallet providers are battling it out to dominate a market that encompasses nearly 100m people.
